Ravensberg

Ravensberg was a county in East Westphalia at the foot of the Teutoburg Forest. In 1337 Count Bernard, the last male of his line, ruled there.

On Bernard's death in 1346 the county passed through his heiress Margaret to Gerhard of Jülich. It was joined with Berg and Jülich-Berg, then with Jülich-Cleves-Berg in 1521. The Treaty of Xanten assigned Ravensberg to Brandenburg in 1614. It formed part of Minden-Ravensberg from 1719, passed to Westphalia in 1807 and returned to Prussia in 1813.
