Answer
After his father's death, Tipu Sultan fought the Second Anglo-Mysore War (1780-1784) against the British East India Company and its allies. This conflict arose due to Tipu's expansionist policies and his alliance with the French, who were also at war with the British. The war ended with the Treaty of Mangalore, which resulted in Tipu's loss of territory and the payment of a large indemnity to the British.
