Q. In which Anglo-Mysore war, the Treaty of Manglore signed?
Answer: Second
Notes: Second Anglo-Mysore war (1780-84): The immediate cause of the war was the attack on the French port Mahe by British
troops led by Warren Hastings. Then, Haider Ali led a joint front with Nizam and Marathas and captured Arcot. But, due to
arrival of Sir Eyre Coote, Haider Ali was defeated in the battles of Porto Novo, Palur and Sholingur. During the war, he died  but his son Tipu Sultan continued the struggle. Mean while, French came to his assistance and finally the Treaty of Manglore (1784) was signed.
