Family

Louis's first wife, Margaret, was the oldest child of Charles, Margrave of Moravia, and his first wife, Blanche of Valois. Margaret was born in 1335. The exact date of the marriage of Louis and Margaret is unknown, but it occurred between 1342 and 1345. Margaret died childless on 7 September 1349.

According to the Chronicle of Parthénope, the Neapolitan princes whom Louis had imprisoned during his first campaign in Southern Italy proposed him to marry Queen Joanna I's younger sister and heir, Mary. She was the widow of Charles of Durazzo, who had been executed on Louis's orders. During the siege of Aversa in the summer of 1350, Louis met her envoy in the nearby Trentola-Ducenta and the terms of their marriage were accepted. However, Mary was forced to marry Robet of Baux after Louis left Southern Italy.

Louis married his second wife, Elizabeth, around 20 June 1353. Elizabeth was the daughter of Stephen II, Ban of Bosnia, and Stephen's wife, Elizabeth of Kuyavia. Louis and his new wife were within the prohibited degree of kinship, because Louis's mother and his wife's grandmother were cousins, but they applied for a papal dispensation only about four months after their marriage. Historian Iván Bertényi says that this haste suggests that Elizabeth, who had been living in the court of Louis's mother, was pregnant at the time of the marriage. If this theory is valid, Louis's and his wife's first child was stillborn. Their next child, Catherine, was born in 1370 and died in 1378. The next daughter, Mary, who would succeed Louis in Hungary, was born in 1371. Louis's youngest daughter, Jadwiga, who was born in 1373, became queen regnant of Poland.
