Last Feud (1559) was a conflict that ended the independence of Dithmarschen, a self-governing peasant republic in what is now northern Germany. A coalition led by Frederick II of Denmark, Adolf, Duke of Holstein-Gottorp and John II, Duke of Schleswig-Holstein-Haderslev, launched an invasion to bring the region under control. The campaign was led by General Johann Rantzau, whose forces defeated the Dithmarschen militia and captured key towns, including Meldorf and Heide.
