Answer
In the Treaty of Seringapatam, Tipu Sultan ceded Malabar and Mangalore to the British East India Company. This loss significantly reduced his territory and weakened his power. The treaty also forced him to pay a large indemnity and surrender several of his forts. The treaty marked a major turning point in the Anglo-Mysore Wars, as it effectively ended Tipu Sultan's resistance to British expansion in South India.
