The 1748 Treaty of Aix-la-Chapelle, sometimes called the Treaty of Aachen, ended the War of the Austrian Succession, following a congress assembled on 24 April 1748 at the Free Imperial City of Aachen. The two main antagonists in the war, Britain and France, opened peace talks in the Dutch city of Breda in 1746.
