Tipu wanted to improve his position by driving the English out of India. Therefore, he sought help from Turkey and France. Cornwallis believed that Tipu having allied with the French would strike against the English. To check Tipu Sultan, the English formed alliances with the Nizam and the Marthas. Tipu attacked Travancore, a friend of the British. So, the English declared war against Tipu Sultan in 1790.
