Life

Isabella was the sixth of ten children, her siblings included Alfonso IV of Aragon and Maria of Aragon.

Her paternal grandparents were Peter III of Aragon and Constance of Sicily. Her maternal grandparents were Charles II of Naples and Maria Arpad of Hungary.

Isabella was originally betrothed to Oshin, King of Armenia, son of Leo II, King of Armenia and his wife Queen Keran. Her father planned her betrothal to Oshin of Armenia in exchange for religious relics of St Thecla, located at Sis in Armenia, which he was anxious to acquire for the cathedral of Tarragona. Negotiations for the marriage broke down in the face of Armenian opposition to increased close ties with the Catholic western powers.

On 11 May 1315, Isabella married Frederick I of Austria, King of Germany in Ravensburg. From then onwards, Isabella was known as Elisabeth in Germany and Austria. Her husband had been elected as one of two rival Kings of Germany in October, 1314. His rival was Louis IV of Bavaria. With her marriage, Isabel became one of two Queens of Germany with Beatrix von Silesia-Glogau, wife of Louis IV.

It is said that Isabella was blind in the last six years of her life.

Isabel and Frederick had at least three children:

• Frederick of Austria (1316–1322).
• Elisabeth of Austria (1317 – 23 October 1336).
• Anna of Austria (1318 – 14 December 1343). Married first Henry XV, Duke of Bavaria and secondly John Henry, Count of Gorizia.

On 5 September 1325, Frederick I and Louis IV resolved their conflict by agreeing to serve as co-rulers. However Frederick soon became the junior co-ruler and retired to Austria until his death on 13 January 1330. Isabella survived him by almost six months. She was buried in Vienna.
