AIX-LA-CHAPELLE, Treaties of Peace Concluded at. The first, 2 May 1668, put an end to the war carried on against Spain by Louis XIV in 1667, after the death of his father-in-law, Philip IV, in support of his claims to a great part of the Spanish Netherlands, which he urged in the name of his queen, the Infanta Maria Theresa, pleading the jus devolutionis prevailing among private persons in Brabant and Namur. The second peace of Aix-la-Chapelle, 18 Oct. 1748, terminated the Austrian War of Succession in which the parties were at first Louis XV of France and the Empress Maria Theresa and, in the sequel, Spain on the one side and Great Britain, Maria Theresa, and Charles Emmanuel, King of Sardinia, on the other.
