Johann II Senn von Münsingen

Johann II Senn von Münsingen (c. 1308–1365), trained in canon law, was elected bishop of Basel by its chapter in 1335. He rebuilt a diocese ruined by his predecessors' wars.

In 1337 he admitted craftsmen to the city council, in a charter that first mentioned Basel's guilds. Charles IV's visit in 1347 ended the interdict on Basel. His rule also saw the plague of 1348 and the great earthquake of 1356, and he died on 30 June 1365 and was buried in Basel Minster.
