Catherine of Hungary

Catherine of Hungary (, ; July 1370 – May 1378), a member of the Capetian House of Anjou, was heir presumptive to the thrones of Hungary and Poland as eldest child of King Louis the Great and his second wife, Elizabeth of Bosnia.

Heir presumptive Catherine's birth was long expected, as her parents, Louis I of Hungary and Elizabeth of Bosnia, were childless for the first seventeen years of their marriage. Her birth also secured the succession to the Holy Crown of Hungary, to which Catherine was heir presumptive all her life.

Being the eldest daughter of the King of Hungary and Poland who had no sons, Catherine was a much wanted bride. When she was only four years old, she was betrothed to Louis, a younger son of King Charles V of France and future Duke of Orléans. Their marriage was supposed to establish a connection between the two branches of the French royal house. Her father made a set of concessions to the Polish noblemen in exchange for recognizing Catherine (or one of her sisters) as sovereign of Poland after his death. This agreement is known as the Privilege of Koszyce.

Thus, Catherine was expected to reign over Hungary and Poland. Her father also planned to leave her his claim to the Crown of Naples and the County of Provence, which were then held by his ailing and childless cousin Joanna I.

Death and aftermath However, Catherine died at the age of seven, predeceasing both her father and her cousin Joanna. The agreement between her father and the noblemen became null and void. Her younger sister Mary, who was betrothed to her fiancé, became heir presumptive and eventually monarch of Hungary. Catherine's youngest sister Jadwiga eventually became monarch of Poland.
