Battle of Frankenhausen

The Battle of Frankenhausen was fought on 14 and 15 May 1525. It was an important battle in the German Peasants' War and the final act of the war in Thuringia: joint troops of Landgrave Philip I of Hesse and Duke George of Saxony defeated the peasants under their spiritual leader Thomas Müntzer near Frankenhausen in the County of Schwarzburg.

On April 29, 1525, the struggles in and around Frankenhausen had culminated into an open revolt. Large parts of the citizenry joined the uprising, occupied the town hall, and stormed the castle of the Counts of Schwarzburg. In the following days, a rising number of insurgents gathered around the town, and when Müntzer arrived with 300 fighters from Mühlhausen on May 11, several thousand peasants of the surrounding Thuringian and Saxon estates camped in the fields and pastures.
