Charles V, Holy Roman Emperor

Charles V (Spanish: Carlos; French: Charles; German: Karl; Dutch: Karel; Italian: Carlo) (24 February 1500 – 21 September 1558) was ruler of both the Spanish Empire from 1516 and the Holy Roman Empire from 1519, as well as of the Habsburg Netherlands from 1506. He voluntarily stepped down from these and other positions by a series of abdications between 1554 and 1556. Through inheritance, he brought together under his rule extensive territories in western, central, and southern Europe, and the Spanish colonies in the Americas and Asia. As a result, his domains spanned nearly four million square kilometers and were the first to be described as "the empire on which the sun never sets".
Charles was the heir of three of Europe's leading dynasties: the Houses of Valois-Burgundy (Netherlands), Habsburg (Holy Roman Empire), and Trastámara (Spain). He inherited the Burgundian Netherlands and the Franche-Comté as heir of the House of Valois-Burgundy. From his own dynasty, the Habsburgs, he inherited Austria and other lands in central Europe. He was also elected to succeed his Habsburg grandfather, Maximilian I, as Holy Roman Emperor, a title held by the Habsburgs since 1440. From the Spanish House of Trastámara, he inherited the crowns of Castile, which was in the process of developing a nascent empire in the Americas and Asia, and Aragon, which included a Mediterranean empire extending to Southern Italy. Charles was the first king to rule Castile and Aragon simultaneously in his own right, and as a result he is sometimes referred to as the first King of Spain. The personal union, under Charles, of the Holy Roman Empire with the Spanish Empire resulted in the closest Europe would come to a universal monarchy since the death of Louis the Pious.
Because of widespread fears that his vast inheritance would lead to the realization of a universal monarchy and that he was trying to create a European hegemony, Charles was the object of hostility from many enemies. His reign was dominated by war, and particularly by three major simultaneous conflicts: the Habsburg-Valois Wars with France, the struggle to halt the Ottoman advance, and the Protestant Reformation resulting in conflict with the German princes. The wars with France, mainly fought in Italy, resulted in recovery of territory lost at the beginning of his reign and included the decisive defeat and capture of Francis I of France at the Battle of Pavia in 1525. France recovered and the wars continued for the remainder of Charles's reign. Enormously expensive, they led to the development of the first modern professional army in Europe, the Tercios.
The struggle with the Ottoman Empire was fought in Hungary and the Mediterranean. After seizing most of eastern and central Hungary in 1526, the Ottomans’ advance was halted at their failed Siege of Vienna in 1529. A lengthy war of attrition, conducted on his behalf by his younger brother Ferdinand, continued for the rest of Charles's reign. In the Mediterranean, although there were some successes, Charles was unable to prevent the Ottomans’ increasing naval dominance and the piratical activity of the Barbary Corsairs. Charles opposed the Reformation and in Germany he was in conflict with the Protestant Princes of the Schmalkaldic League who were motivated by both religious and political opposition to him. He could not prevent the spread of Protestantism and although he won a decisive victory against the Princes at the Battle of Mühlberg, 1547, he was ultimately forced to concede the Peace of Augsburg of 1555, which divided Germany on confessional lines.
While Charles did not typically concern himself with rebellions, he was quick to put down three particularly dangerous rebellions in the vital territories of Castile, the Frisian lands, and later in his reign in the port city of Ghent. Once the rebellions were quelled the essential Castilian and Burgundian territories remained mostly loyal to Charles throughout his rule.
Charles’s Spanish dominions were the chief source of his power and wealth, and they became increasingly important as his reign progressed. In the Americas, Charles sanctioned the conquest by Castillian conquistadors of the Aztec and Inca empires. Castillian control was extended across much of South and Central America. The resulting vast expansion of territory and the flows of South American silver to Castile had profound long term effects on Spain.
Charles was only 56 when he abdicated, but after 34 years of energetic rule he was physically exhausted and sought the peace of a monastery, where he died at the age of 58. Upon Charles’s abdications, the Holy Roman Empire was inherited by his younger brother Ferdinand, who had already been given the Austrian lands in 1521. The Spanish Empire, including the possessions in the Netherlands and Italy, was inherited by Charles’s son Philip II. The two empires would remain allies until the 18th century.

Charles was born in 1500 as the eldest son of Philip the Handsome and Joanna of Castile in the Flemish city of Ghent, which was part of the Habsburg Netherlands. The culture and courtly life of the Burgundian Low Countries were an important influence in his early life. He was tutored by William de Croÿ (who would later become his first prime minister), and also by Adrian of Utrecht (later Pope Adrian VI). It is said that Charles spoke several vernacular languages: he was fluent in French and Dutch, later adding an acceptable Castilian Spanish (which Charles called the "divine language") required by the Castilian Cortes Generales as a condition for becoming King of Castile. He also gained a decent command of German (in which he was not fluent prior to his election), though he never spoke it as well as French. A witticism sometimes attributed to Charles is: "I speak Spanish to God, Italian to women, French to men and German to my horse." A variant of the quote is attributed to him by Swift in his 1726 Gulliver's Travels, but there are many other variants and it is often attributed instead to Frederick the Great.

From his Burgundian ancestors he inherited an ambiguous relationship with the Kings of France. Charles shared with France his mother tongue and many cultural forms. In his youth he made frequent visits to Paris, then the largest city of Western Europe. In his words: "Paris is not a city, but a universe" (Lutetia non urbs, sed orbis). He was betrothed to both Louise and Charlotte of Valois, daughters of King Francis I of France, but they both died in childhood. Charles also inherited the tradition of political and dynastic enmity between the royal and the Burgundian ducal lines of the Valois dynasty. Charles was very attached to the Burgundian Low Countries where he had been raised. These lands were very rich and contributed significantly to the wealth of the Empire. He also spent much time there, mainly in Brussels. This stands in contrast with the attitude of his son Philip who only visited the Low Countries once.

Until the 1540s, Charles did not spend much time in Germany (apart from the Netherlands). He frequently was in Northern Italy (then part of the Holy Roman Empire). He never actually governed his Austrian dominions and made his brother Ferdinand the ruler of these lands in 1521, as well as his representative in the Holy Roman Empire during his absence. In spite of this, the Emperor had a close relationship with some German families, like the House of Nassau, many of which were represented at his court in Brussels. Some German princes or noblemen accompanied him in his military campaigns against France or the Ottomans, and the bulk of his army was generally composed of German troops, especially the Imperial Landsknechte. Indeed, in 1519, he was elected because he was considered a German prince while his main opponent was French. Nonetheless, in the long term, the growth of Lutheranism and Charles' staunch Catholicism alienated him from various German princes who finally fought against him in the 1540s and the 1550s. It is important to note, though, that other states of the Empire chose to support him in his war, and that he had the constant support of his brother, in spite of their strained personal relationship. Whereas Charles spent much of his final years as a ruler trying to address the issue of religion in the Empire, it would ultimately be Ferdinand, by then much more popular in Germany, who would bring peace to the German lands.

Though Spain was the core of his personal possessions and though he had many Iberian ancestors, in his earlier years Charles felt as if he were viewed as a foreign prince. He became fluent in Spanish late in his life, as it was not his first language. Nonetheless, he spent much of his life in Spain, including his final years in a Spanish monastery, and his heir, later Philip II, was born and raised in Spain. Indeed, Charles's motto, Plus Ultra ('Further Beyond'), became the national motto of Spain. He had many Spanish counselors and, except for the revolt of the comuneros in the 1520s, Spain remained mostly loyal to him. Spain was also his most important military asset, as it provided a great number of generals, as well as the formidable Spanish tercios, considered the best infantry of its time. Many Spaniards, however, believed that their resources were being used to sustain a policy that was not in the country's interest. They usually believed that Charles should have focused on the Mediterranean and North Africa instead of Northern or Central Europe.

In 1506, Charles inherited his father's Burgundian territories, most notably the Low Countries and Franche-Comté. Most of the holdings were fiefs of the German Kingdom (part of the Holy Roman Empire), except his birthplace of Flanders, which was still a French fief, a last remnant of what had been a powerful player in the Hundred Years' War. As he was a minor, his aunt Margaret of Austria (born as Archduchess of Austria and in both her marriages as the Dowager Princess of Asturias and Dowager Duchess of Savoy) acted as regent, as appointed by Emperor Maximilian until 1515. She soon found herself at war with France over the question of Charles' requirement to pay homage to the French king for Flanders, as his father had done. The outcome was that France relinquished its ancient claim on Flanders in 1528.

From 1515 to 1523, Charles's government in the Netherlands also had to contend with the rebellion of Frisian peasants (led by Pier Gerlofs Donia and Wijard Jelckama). The rebels were initially successful but after a series of defeats, the remaining leaders were captured and decapitated in 1523.

Charles extended the Burgundian territory with the annexation of Tournai, Artois, Utrecht, Groningen and Guelders. The Seventeen Provinces had been unified by Charles's Burgundian ancestors, but nominally were fiefs of either France or the Holy Roman Empire. In 1549, Charles issued a Pragmatic Sanction, declaring the Low Countries to be a unified entity of which his family would be the heirs.

The Low Countries held an important place in the Empire. For Charles V personally they were his home, the region where he was born and spent his childhood. Because of trade and industry and the wealth of the region's cities, the Low Countries also represented an important income for the Imperial treasury.

The Burgundian territories were generally loyal to Charles throughout his reign. The important port city of Ghent rebelled in 1539 due to heavy tax payments demanded by Charles. The rebellion did not last long, however, as Charles's military response, with reinforcement from the Duke of Alba, was swift and humiliating to the rebels of Ghent.

Spain

The city of Toledo was the imperial capital and main seat of Charles V, Holy Roman Emperor, and his court.

In the Castilian Cortes of Valladolid in 1506 and of Madrid in 1510, Charles was sworn as the Prince of Asturias, heir-apparent to his mother the Queen Joanna. On the other hand, in 1502, the Aragonese Corts gathered in Saragossa and pledged an oath to Joanna as heiress-presumptive, but the Archbishop of Saragossa expressed firmly that this oath could not establish jurisprudence, that is to say, modify the right of the succession, except by virtue of a formal agreement between the Cortes and the King. So, upon the death of King Ferdinand II of Aragon, on 23 January 1516, Joanna inherited the Crown of Aragon, which consisted of Catalonia, Valencia, Naples, Sicily and Sardinia, while Charles became Governor General. Nevertheless, the Flemings wished Charles to assume the royal title, and this was supported by his grandfather the emperor Maximilian I and Pope Leo X. Thus, after the celebration of Ferdinand II's obsequies on 14 March 1516, Charles was proclaimed king of the crowns of Castile and Aragon jointly with his mother. Finally, when the Castilian regent Cardinal Jiménez de Cisneros accepted the fait accompli, he acceded to Charles's desire to be proclaimed king and imposed his enstatement throughout the kingdom. Charles arrived in his new kingdoms in autumn of 1517. Jiménez de Cisneros came to meet him but fell ill along the way, not without a suspicion of poison, and he died before meeting the King.

Due to the irregularity of Charles assuming the royal title while his mother, the legitimate queen, was alive, the negotiations with the Castilian Cortes in Valladolid (1518) proved difficult. In the end Charles was accepted under the following conditions: he would learn to speak Castilian; he would not appoint foreigners; he was prohibited from taking precious metals from Castile; and he would respect the rights of his mother, Queen Joanna. The Cortes paid homage to him in Valladolid in February 1518. After this, Charles departed to the crown of Aragon. He managed to overcome the resistance of the Aragonese Cortes and Catalan Corts, and he was finally recognized as king of Aragon and count of Barcelona jointly with his mother. The Kingdom of Navarre had been invaded by Ferdinand of Aragon jointly with Castile in 1512, but he pledged a formal oath to respect the kingdom. On Charles's accession to the Spanish throne, the Parliament of Navarre (Cortes) required him to attend the coronation ceremony (to become Charles IV of Navarre), but this demand fell on deaf ears, and the Parliament kept piling up grievances.

Charles was accepted as sovereign, even though the Spanish felt uneasy with the Imperial style. Spanish kingdoms varied in their traditions. Castile was an authoritarian kingdom, where the monarch's own will easily overrode law and the Cortes. By contrast, in the kingdoms of the crown of Aragon, and especially in the Pyrenean kingdom of Navarre, law prevailed, and the monarchy was a contract with the people. This became an inconvenience and a matter of dispute for Charles V and later kings, since realm-specific traditions limited their absolute power. With Charles, government became more absolute, even though until his mother's death in 1555 Charles did not hold the full kingship of the country.

Soon resistance to the Emperor arose because of heavy taxation to support foreign wars in which Castilians had little interest, and because Charles tended to select Flemings for high offices in Spain and America, ignoring Castilian candidates. The resistance culminated in the Revolt of the Comuneros, which Charles suppressed. Immediately after crushing the Castilian revolt, Charles was confronted again with the hot issue of Navarre when King Henry II attempted to reconquer the kingdom. Main military operations lasted until 1524, when Hondarribia surrendered to Charles's forces, but frequent cross-border clashes in the western Pyrenees only stopped in 1528 (Treaties of Madrid and Cambrai).

After these events, Navarre remained a matter of domestic and international litigation still for a century (a French dynastic claim to the throne did not end until the French Revolution in 1789). Charles wanted his son and heir Philip II to marry the heiress of Navarre, Jeanne d'Albret. Jeanne was instead forced to marry William, Duke of Julich-Cleves-Berg, but that childless marriage was annulled after four years. She next married Antoine de Bourbon, and both she and their son would oppose Philip II in the French Wars of Religion.

Castile became integrated into Charles's empire, and provided the bulk of the empire's financial resources as well as its most effective military units. The enormous budget deficit accumulated during Charles's reign resulted in Spain declaring bankruptcy during the reign of Philip II.

Italy

The Crown of Aragon inherited by Charles included the Kingdom of Naples, the Kingdom of Sicily and the Kingdom of Sardinia. Aragon also previously controlled the Duchy of Milan, but a year before Charles ascended to the throne, it was annexed by France after the Battle of Marignano in 1515. Charles succeeded in re-capturing Milan in 1522, when Imperial troops defeated the Franco-Swiss army at Bicocca. Yet in 1524 Francis I of France retook the initiative, crossing into Lombardy where Milan, along with a number of other cities, once again fell to his attack. Pavia alone held out, and on 24 February 1525 (Charles's twenty-fifth birthday), Charles's Spanish forces captured Francis and crushed his army in the Battle of Pavia, yet again retaking Milan and Lombardy. Spain successfully held on to all of its Italian territories, though they were invaded again on multiple occasions during the Italian Wars.

In addition, Habsburg trade in the Mediterranean was consistently disrupted by the Ottoman Empire. In 1538 a Holy League consisting of all the Italian states and Spain was formed to drive the Ottomans back, but it was defeated at the Battle of Preveza. Decisive naval victory eluded Charles; it would not be achieved until after Charles's death, at the Battle of Lepanto in 1571.

America

During Charles's reign, the Spanish territories in the Americas were considerably extended by conquistadores like Hernán Cortés and Francisco Pizarro. They conquered the large Aztec and Inca empires and incorporated them into the Empire as the Viceroyalties of New Spain and Peru between 1519 and 1542. Combined with the circumnavigation of the globe by the Magellan expedition in 1522, these successes convinced Charles of his divine mission to become the leader of Christendom, which still perceived a significant threat from Islam. The conquests also helped solidify Charles's rule by providing the state treasury with enormous amounts of bullion. As the conquistador Bernal Díaz del Castillo observed, "We came to serve God and his Majesty, to give light to those in darkness, and also to acquire that wealth which most men covet."

In 1528 Charles assigned a concession in Venezuela Province to Bartholomeus V. Welser, in compensation for his inability to repay debts owed. The concession, known as Klein-Venedig (little Venice), was revoked in 1546. In 1550, Charles convened a conference at Valladolid in order to consider the morality of the force used against the indigenous populations of the New World, which included figures such as Bartolomé de las Casas.

Charles V is credited with the first idea of constructing an American Isthmus canal in Panama as early as 1520.

Holy Roman Empire

After the death of his paternal grandfather, Maximilian, in 1519, Charles inherited the Habsburg Monarchy. He was also the natural candidate of the electors to succeed his grandfather as Holy Roman Emperor. He defeated the candidacies of Frederick III, Elector of Saxony, Francis I of France, and Henry VIII of England. The electors gave Charles the crown on 28 June 1519. In 1530, he was crowned Holy Roman Emperor by Pope Clement VII in Bologna, the last emperor to receive a papal coronation.

Despite holding the imperial throne, Charles's real authority was limited by the German princes. They gained a strong foothold in the Empire's territories, and Charles was determined not to let this happen in the Netherlands. An inquisition was established as early as 1522. In 1550, the death penalty was introduced for all cases of unrepentant heresy. Political dissent was also firmly controlled, most notably in his place of birth, where Charles, assisted by the Duke of Alba, personally suppressed the Revolt of Ghent in mid-February 1540.

Charles abdicated as emperor in 1556 in favor of his brother Ferdinand; however, due to lengthy debate and bureaucratic procedure, the Imperial Diet did not accept the abdication (and thus make it legally valid) until 24 February 1558. Up to that date, Charles continued to use the title of emperor.

France

Much of Charles's reign was taken up by conflicts with France, which found itself encircled by Charles's empire while it still maintained ambitions in Italy. In 1520, Charles visited England, where his aunt, Catherine of Aragon, urged her husband, Henry VIII, to ally himself with the emperor. In 1508 Charles was nominated by Henry VII to the Order of the Garter. His Garter stall plate survives in Saint George's Chapel.

Francis I and Charles V made peace at the Truce of Nice in 1538. Francis actually refused to meet Charles in person, and the treaty was signed in separate rooms.

The first war with Charles's great nemesis Francis I of France began in 1521. Charles allied with England and Pope Leo X against the French and the Venetians, and was highly successful, driving the French out of Milan and defeating and capturing Francis at the Battle of Pavia in 1525. To gain his freedom, Francis ceded Burgundy to Charles in the Treaty of Madrid, as well as renouncing his support of Henry II's claim over Navarre.

When he was released, however, Francis had the Parliament of Paris denounce the treaty because it had been signed under duress. France then joined the League of Cognac that Pope Clement VII had formed with Henry VIII of England, the Venetians, the Florentines, and the Milanese to resist imperial domination of Italy. In the ensuing war, Charles's sack of Rome (1527) and virtual imprisonment of Pope Clement VII in 1527 prevented the Pope from annulling the marriage of Henry VIII of England and Charles's aunt Catherine of Aragon, so Henry eventually broke with Rome, thus leading to the English Reformation. In other respects, the war was inconclusive. In the Treaty of Cambrai (1529), called the "Ladies' Peace" because it was negotiated between Charles's aunt and Francis' mother, Francis renounced his claims in Italy but retained control of Burgundy.

A third war erupted in 1536. Following the death of the last Sforza Duke of Milan, Charles installed his son Philip in the duchy, despite Francis's claims on it. This war too was inconclusive. Francis failed to conquer Milan, but he succeeded in conquering most of the lands of Charles's ally, the Duke of Savoy, including his capital Turin. A truce at Nice in 1538 on the basis of uti possidetis ended the war but lasted only a short time. War resumed in 1542, with Francis now allied with Ottoman Sultan Suleiman I and Charles once again allied with Henry VIII. Despite the conquest of Nice by a Franco-Ottoman fleet, the French could not advance toward Milan, while a joint Anglo-Imperial invasion of northern France, led by Charles himself, won some successes but was ultimately abandoned, leading to another peace and restoration of the status quo ante bellum in 1544.

A final war erupted with Francis' son and successor, Henry II, in 1551. Henry won early success in Lorraine, where he captured Metz, but French offensives in Italy failed. Charles abdicated midway through this conflict, leaving further conduct of the war to his son, Philip II, and his brother, Ferdinand I, Holy Roman Emperor.

Conflicts with the Ottoman Empire

Charles fought continually with the Ottoman Empire and its sultan, Suleiman the Magnificent. The defeat of Hungary at the Battle of Mohács in 1526 "sent a wave of terror over Europe." The Muslim advance in Central Europe was halted at the Siege of Vienna in 1529.

Suleiman won the contest for mastery of the Mediterranean, in spite of Spanish victories such as the conquest of Tunis in 1535. The regular Ottoman fleet came to dominate the Eastern Mediterranean after its victories at Preveza in 1538 and Djerba in 1560 (shortly after Charles's death), which severely decimated the Spanish marine arm. At the same time, the Muslim Barbary corsairs, acting under the general authority and supervision of the sultan, regularly devastated the Spanish and Italian coasts, crippling Spanish trade and chipping at the foundations of Habsburg power.

In 1536 Francis I of France allied himself with Suleiman against Charles. While Francis was persuaded to sign a peace treaty in 1538, he again allied himself with the Ottomans in 1542 in a Franco-Ottoman alliance. In 1543 Charles allied himself with Henry VIII and forced Francis to sign the Truce of Crépy-en-Laonnois. Later, in 1547, Charles signed a humiliating treaty with the Ottomans to gain himself some respite from the huge expenses of their war.

Charles V made overtures to the Safavid Empire to open a second front against the Ottomans, in an attempt at creating a Habsburg-Persian alliance. Contacts were positive, but rendered difficult by enormous distances. In effect, however, the Safavids did enter in conflict with the Ottoman Empire in the Ottoman-Safavid War, forcing it to split its military resources.

Protestant Reformation

As Holy Roman Emperor, Charles called Martin Luther to the Diet of Worms in 1521, promising him safe conduct if he would appear. Initially dismissing Luther's theses as "an argument between monks", he later outlawed Luther and his followers in that same year but was tied up with other concerns and unable to take action against Protestantism. The Peasants' Revolt in Germany broke out from 1524 to 1526, and in 1531 the Lutheran Schmalkaldic League was formed. Charles delegated increasing responsibility for Germany to his brother Ferdinand while he concentrated on problems elsewhere.

In 1545, the opening of the Council of Trent began the Counter-Reformation, and Charles won to the Catholic cause some of the princes of the Holy Roman Empire. In 1546 (the year of Luther's natural death), he outlawed the Schmalkaldic League (which had occupied the territory of another prince). The next year his forces drove the League's troops out of southern Germany, and defeated John Frederick, Elector of Saxony and Philip of Hesse at the Battle of Mühlberg, capturing both. At the Augsburg Interim in 1548, he created a solution giving certain allowances to Protestants until the Council of Trent would restore unity. However, members of both sides resented the Interim and some actively opposed it. In 1552 Protestant princes, in alliance with Henry II of France, rebelled again, which caused Charles to retreat to the Netherlands.

Charles suffered from an enlarged lower jaw, a deformity that became considerably worse in later Habsburg generations, giving rise to the term Habsburg jaw. This deformity was caused by the family's long history of inbreeding, which was commonly practiced in royal families of that era to maintain dynastic control of territory. He struggled to chew his food properly and consequently experienced bad digestion for much of his life. As a result, he usually ate alone.

He suffered from epilepsy and was seriously afflicted with gout, presumably caused by a diet consisting mainly of red meat. As he aged, his gout progressed from painful to crippling. In his retirement, he was carried around the monastery of St. Yuste in a sedan chair. A ramp was specially constructed to allow him easy access to his rooms.

Charles abdicated the parts of his empire piecemeal. First he abdicated the thrones of Sicily and Naples, both fiefs of the Papacy, and the Duchy of Milan to his son Philip in 1554. Upon Charles's abdication of Naples on 25 July, Philip was invested with the kingdom (officially "Naples and Sicily") on 2 October by Pope Julius III. The abdication of the throne of Sicily, sometimes dated to 16 January 1556, must have taken place before Joanna's death in 1555. There is a record of Philip being invested with this kingdom (officially "Sicily and Jerusalem") on 18 November 1554 by Julius. These resignations are confirmed in Charles's will from the same year. The most famous—and public—abdication of Charles took place a year later, on 25 October 1555, when he announced to the States General of the Netherlands his abdication of those territories and the county of Charolais and his intention to retire to a monastery. He abdicated as ruler of the Spanish Empire in January 1556, with no fanfare, and gave these possessions to Philip. In September 1556, he abdicated as Holy Roman Emperor in favor of his brother Ferdinand, although the abdication was not formally accepted by the Electors of the Empire until 1558. The delay had been at Ferdinand's request who had been concerned about holding a risky election in 1556.

Charles retired to the monastery of Yuste in Extremadura, but continued to correspond widely and kept an interest in the situation of the empire. He suffered from severe gout. Some scholars think Charles decided to abdicate after a gout attack in 1552 forced him to postpone an attempt to recapture the city of Metz, where he was later defeated. He lived alone in a secluded monastery, with clocks lining every wall, which some historians believe were symbols of his reign and his lack of time.

Charles died on 21 September 1558 from malaria. Twenty-six years later, his remains were transferred to the Royal Pantheon of the Monastery of San Lorenzo de El Escorial.

On 10 March 1526, Charles married his first cousin Isabella of Portugal, sister of John III of Portugal, in Seville. They had six children:

Philip II of Spain		21 May 1527 – 13 September 1598	Only surviving son, successor of his father in the Spanish crown.
Maria		21 June 1528 – 26 February 1603	Married her first cousin Maximilian II, Holy Roman Emperor.
Ferdinand		22 November 1529 – 13 July 1530	Died in infancy.

John		19 October 1537 – 20 March 1538	Died in infancy.
Son		21 April 1539	Stillborn.

Isabella often administered Spain while Charles was in other lands. Due to Philip II being a grandson of Manuel I of Portugal through his mother he was in the line of succession to the throne of Portugal, and claimed it after his uncle's death (Henry, the Cardinal-King, in 1580), thus establishing the Iberian Union.

Charles also had four illegitimate children:

• Margaret of Austria (1522 – 1586), daughter of Johanna Maria van der Gheynst, a servant of Charles I de Lalaing, Seigneur de Montigny, daughter of Gilles Johann van der Gheynst and wife Johanna van der Caye van Cocamby. Married firstly with Alessandro de' Medici, Duke of Florence and secondly with Ottavio Farnese, Duke of Parma.
• Joanna of Austria (1522 – 1530), daughter of a noble lady from Nassau.
• Tadea of Austria (1523? – ca. 1562), daughter of Orsolina della Penna. Married with Sinibaldo di Copeschi.
• John of Austria (1547 – 1578), son of Barbara Blomberg, victor of the Battle of Lepanto

Historians suspect he fathered Isabel of Castile, the illegitimate daughter of his step-grandmother Germaine of Foix.

Converesely, in Charles De Coster's masterpiece Thyl Ulenspiegel (1867), after his death Charles V is consigned to Hell as punishment for the acts of the Inquisition under his rule, his punishment being that he would feel the pain of anyone tortured by the Inquisition. De Coster's book also mentions the story on the spectacles in the coat of arms of Oudenaarde, the one about a paysant of Berchem in Het geuzenboek (1979) by Louis Paul Boon, while Abraham Hans (nl) (1882–1939) included both tales in De liefdesavonturen van keizer Karel in Vlaanderen.
