European countries made two important peace agreements in Aachen. In 1668, the first treaty (agreement) ended the War of Devolution between France and the alliance of England, Holland and Sweden. The treaty allowed France to keep most of the towns it had captured in Flanders the year before. In 1748, the second treaty ended the War of the Austrian Succession. In this war, France, Prussia, and other nations tried to take territory from the Austrian Empire. The treaty said that Maria Theresa of Austria was the ruler of these territories. It also gave Prussia the territory of Silesia.
