Grafschaft Mark
Vest Recklinghausen was an ecclesiastical territory in the Holy Roman Empire, located in the center of today's North Rhine-Westphalia. The rivers Emscher and Lippe formed the border with the County of Mark and Essen Abbey in the south, and to the Bishopric of Münster in the north. In the east, a fortification secured the border with Dortmund and in the west it was bordered by the Duchy of Cleves.
