John I of Bavaria

John I of Bavaria (1329–1340), called John the Child, was the only son of Duke Henry XIV of Lower Bavaria and Margaret of Bohemia, daughter of King John the Blind. In 1339 he married Anna, daughter of Emperor Louis IV, in Munich, sealing peace between the Wittelsbach branches. When Henry died that September, the emperor became his guardian.

John ruled Lower Bavaria only a year, dying at Landshut aged eleven; with him the Lower Bavarian line ended and Louis IV reunited the duchy divided in 1255.
