Q. When did the Treaty of Aix-la-Chapelle signed? Answer:
1748
Notes: The First Carnatic (1744-48) war was fought between Britishers and the French due to Austrian war of succession in Europe. The French forces under Dupleix defeated the English and captured Madras. Then, in 1748 AD, the peace treaty of Aix-la-Chapelle was signed and Madras was restored to the British and the exchange of war prisoners took place.
