Kempten
Kempten was a Benedictine princely abbey in the Allgäu. In 1337 its lands surrounded the rival Free Imperial City of Kempten, which had separated in 1289.
The city turned Protestant in 1527, while the abbey joined the Catholic League. Swedish troops burned the monastery in 1632, and the abbey held the Holy Roman Empire's last witch trial in 1775. Secularised to Bavaria in 1803, the abbey's territory was united with the city in 1819.
