Swabian League
In 1377 Reutlingen was the scene of a victory by the Swabian League, formed in the previous year by 14 Swabian cities, led by Ulm, over the Count of Württemberg. In 1519, a later Swabian League came to Reutlingen's help when Ulrich, Duke of Württemberg attempted to seize the city; the League landed a crushing blow, conquering Württemberg and selling it to Charles V.
