How did the Mysore Wars lead to British control of Mysore?

British control over Mysore was established through four military confrontations known as the Mysore Wars, which gradually eroded the power of the state's rulers, Hyder Ali and his son Tipu Sultan.

• Early Conflicts: Initial wars in the late 18th century saw Mysore successfully resist British expansion, with Hyder Ali dictating peace terms in 1769 and the Treaty of Mangalore concluding the second war in 1784.12
• Third War: In 1792, following the third war, Tipu Sultan was defeated at Seringapatam and forced to cede half of his dominions to the East India Company and its allies.1
• Final Conquest: The fourth war in 1799, initiated by Lord Wellesley under the pretext of countering French influence, resulted in the storming of Seringapatam and the death of Tipu Sultan.13

Following this victory, the British restored a child from the former Hindu royal family as a puppet ruler, effectively placing the state under British control through the subsidiary system, which required states to cede territory and surrender control of their foreign relations in exchange for British military protection.3
