Henry XIII, Duke of Bavaria

He was the younger son of Otto II and Agnes of Brunswick.

In 1254, he succeeded his father together with his brother Louis II in Bavaria and the Palatinate. The brothers divided their land in 1255 against the law. Henry received Lower Bavaria and Louis Upper Bavaria and the Palatinate. It was the first of many divisions of the duchy. Henry resided in Landshut and, in 1255, the work for the main castle of Burghausen Castle was begun.

As the division of the duchy was against the law, it caused anger of the Bishops in Bavaria who allied with Ottokar II of Bohemia in 1257. In August 1257, Ottokar invaded Bavaria, but Henry and Louis managed to repulse the attack. It was one of the rare concerted and harmonious actions of both brothers who often argued. Henry was also later several times at war against the Archbishopric of Salzburg and the Bishop of Passau. During the conflict of King Rudolph I of Germany with Ottokar II, Duke Henry repeatedly changed allegiance.

During Duke Henry's reign, the Bavarian Peace Ordinances were put into place in his domains, stating, "Anyone out of doors at night without a lantern is violating the peace and is suspect of crime." The ordinances extend further for the city of Landshut that anyone carrying a sword or dagger by day or night was liable to heavy penalties.[1]

Henry XIII was succeeded by his oldest son Otto III, who also became King of Hungary. Henry's branch died out in 1340 and was inherited by Louis' son Emperor Louis IV.
