Margaret of Cleves

Margaret of Cleves (c. 1310 – after 1348) was a daughter of Count Dietrich VIII of Cleves and Margaret of Guelders. In 1332 she married Count Adolf II of the Marck, bearing him seven children, among them Engelbert III and Adolf III.

In 1333 her father issued an inheritance law settling Cleves on Margaret and her sisters, but his brother John had it repealed in 1338. After Adolf and Dietrich both died in 1347, Margaret pressed her claim against John, who prevailed; her son Adolf finally secured the county in 1368.
