The East Frisian-Gueldrian War of 1531–1534, also known as the Gueldrian Feud was a conflict between Counts Enno II and Johan I of East Frisia on the one hand, and Balthasar von Esens and Duke Charles II of Guelders on the other. In this war, which lasted from 1531 to 1534, East Frisia suffered severe devastation. The war came to an end in 1534 with the Peace of Logum.
