He was Prince of Beira, Duke of Braganza, Prince of Brazil and heir apparent to the throne of Portugal as the oldest son of Queen Maria I of Portugal and her husband and uncle King consort Pedro III. On February 21, 1777, when he was 15 years old, he married his 30-year-old aunt the Infanta Benedita of Portugal. Benedita was an attractive woman and the main candidate for the wife of José.

Three days after their wedding, José's grandfather and Benedita's father the old king José died, and his mother succeeded as queen regnant.
