The Duchy of Cleves was a historical territory located in the western part of present-day Germany. It emerged in the 14th century and became a significant political entity during the late Middle Ages. 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 through its connection to the House of Cleves, which played a role in the politics of the Holy Roman Empire. The duchy eventually became part of the Duchy of Prussia in the 17th century, marking the end of its independent status.
