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 1583, although much of the territory was already Protestant, the Calvinist Elector of Cologne, Gebhard, Truchsess von Waldburg and his wife, Agnes, ordered the destruction of the icons and decorative elements of the churches.
In 1586, the territory was invaded by Martin Schenck and Hermann Cloedt, who caused great damage to the farms and small villages, and were besieged by Claude de Berlaymont, also known as Haultpenne, in the city of Werl.
During the secularization of the ecclesiastical states in 1802–03, also known as the German Mediatisation, the electorate was abolished and Vest Recklinghausen was annexed by the Dukes of Arenberg.
