Moers
Moers was a county on the Lower Rhine's left bank, including Moers town and the Krefeld exclave. Count Dietrich of Moers held it in 1337 under the overlordship of Cleves.
In 1399 Frederick III inherited Saarwerden, but Burgundy's Charles the Bold overran Moers in 1473. After the native dynasty died out in 1578, Orange-Nassau and Cleves contested the county. The Orange princes held it from 1600; Prussia took it in 1702, made it a principality in 1705 and regained it after French annexation in 1815.
