Charles I, also known as
Charles Robert (; ; 128816 July 1342) was
King of Hungary and
Croatia from 1308. He was a member of the
Capetian House of Anjou. His paternal grandmother,
Mary, was a daughter of
Stephen V of Hungary. Charles inherited the claim of his father,
Charles Martel, Prince of Salerno, to the
Kingdom of Hungary in 1295. However, most Hungarian
prelates and lords refused to acknowledge his claim and remained loyal to
Andrew III of Hungary. Charles's paternal grandfather,
Charles II of Naples, made Charles's uncle,
Robert, heir to the
Kingdom of Naples even though Robert was a younger brother of Charles's father.
