The Duchy of Cleves was a historical territory located in the western part of present-day Germany. It emerged in the late Middle Ages and became a significant political entity in the region. The duchy was known for its strategic location along the Rhine River and its involvement in various regional conflicts and alliances. In the 16th century, the Duchy of Cleves gained prominence due to its connection to the House of Hohenzollern and its role in the Reformation. The duchy eventually became part of the Prussian Empire in the 17th century, marking the end of its independence and influence in European politics.
