John II, Duke of Bavaria

His maternal grandparents were Frederick III of Sicily and Eleanor of Anjou. Her parents were Charles II of Naples and Maria Arpad of Hungary.

Maria was a daughter of Stephen V of Hungary and his wife, queen Elisabeth, who was daughter of Zayhan of Kuni, a chief of the Cuman tribe and had been a pagan before her marriage.

Stephen V was a son of Béla IV of Hungary and Maria Laskarina. Maria Laskarina was a daughter of Theodore I Lascaris and Anna Angelina. Anna was a daughter of Eastern Roman Emperor Alexius III and Euphrosyne Doukaina Kamaterina.

From 1375 to 1392 John ruled in Bavaria-Landshut with his brothers Stephen III and Frederick. In 1385 John II and his wife inherited a third of County of Gorizia with Lienz, but already in 1392 he sold his part to the Habsburgs. In 1392 John initiated a new partition of Bavaria since he refused to finance the Italian adventures of his brothers who were both married with daughters of Bernabò Visconti but also Stephen's expensive holding of court. The duchy of Bavaria-Landshut then was reduced since Bavaria-Ingolstadt and Bavaria-Munich were created. Frederick kept Bavaria-Landshut while Stephen received Bavaria-Ingolstadt which he soon treated as a disadvantage. Therefore, John ruled Bavaria-Munich for three years only until 1395, then he shared his power again with Stephen after an armed conflict between both brothers.

John II was succeeded by his sons Ernest and William III who finally managed to enforce their sole rule over Bavaria-Munich against Stephen III. John is buried in the FrauenkircheinMunich.

John married in 1372 Catherine of Gorizia,^[1] a daughter of Count Meinhard VI of Gorizia and Catharina of Pfannberg. Their children were:

1. Ernest I of Bavaria-Munich (1373–2 July 1438, Munich)^[1]
2. William III of Bavaria-Munich (1375, Munich–1435, Munich).
3. Sofia of Bavaria (1376–26 September 1425, Pressburg), married in Prague 2 May 1389 King Wenceslaus.

He also had an illegitimate son, Johann Grünwalder (1393–1452), who was Cardinal and Bishop of Freising.
