Rudolph van Coevorden

Rudolph van Coevorden was a thirteenth century feudal lord who led a rebellion against Otto II of Lippe Bishop of Utrecht, defeating and killing Otto at the Battle of Ane in 1228. Rudolph was later murdered by Otto's successor, Wilbrand van Oldenburg, leading to the inconclusive Friso-Drentic War from 1230-1233.
