João Manuel, Prince of Portugal (Portuguese pronunciation: [ʒuˈɐ̃w̃ mɐnuˈɛɫ]) (3 June 1537 – 2 January 1554) was a Portuguese infante (prince), the eighth son of King John III of Portugal by his wife Catherine of Austria, daughter of Philip I of Castile and Joanna of Castile. As the heir to the throne he was styled Prince of Portugal.
Early life

João Manuel was born on 3 June 1537 in the Royal Palace of Évora and became the heir to the throne of Portugal in 1539. He survived his four older brothers who died in childhood but was a sickly teenager. The successive inter-marriages between the houses of Spain and Portugal are believed to have some responsibility for his ill health. In 1552 he married Princess Joanna of Spain, his first cousin, through both paternal and maternal line, daughter of his paternal aunt Isabella of Portugal and of his maternal uncle, Emperor Charles V.
Death
João Manuel died of what the sources refer to as consumption, which may refer to tuberculosis, on 2 January 1554, but some historians believe his death occurred as a result of diabetes, a disease he may have inherited from his maternal grandfather Philip I. Eighteen days later, a posthumous son was born from his marriage: the future King Sebastian I of Portugal.
