Mysore Wars — Key Changes

Regulating Act of 1773	1773	This Act was the first major parliamentary intervention to regulate the affairs of the British East India Company in India. It appointed a Governor-General of Bengal (Warren Hastings) and established a Supreme Court in Calcutta.	While not directly an 'amendment' to Mysore's administration, it significantly impacted the British conduct of the Mysore Wars. It centralized British political and military authority under the Governor-General, leading to more coordinated (though not always successful) campaigns, especially during the Second Mysore War. It aimed to curb the independent actions of the Madras Presidency, which often complicated relations with Mysore.
Pitt's India Act of 1784	1784	This Act further strengthened parliamentary control over the Company's administration in India. It established a Board of Control in Britain to oversee the Company's civil, military, and revenue affairs, and subordinated the presidencies of Madras and Bombay to the Governor-General of Bengal.	This Act streamlined British policy-making and military strategy, particularly evident in the Third and Fourth Mysore Wars. It ensured a more unified approach under Governor-Generals like Cornwallis and Wellesley, who pursued aggressive expansionist policies against Mysore with greater central authority and resources. This reduced internal conflicts within the British administration, making them a more formidable and coherent adversary.
Subsidiary Alliance System	1798 (formalized by Wellesley)	Though not a constitutional amendment, it was a significant policy shift. It required Indian rulers to disband their own armies, maintain a British contingent within their territory, and pay for its upkeep. In return, the British promised protection from external and internal threats.	The Subsidiary Alliance was the direct instrument of Mysore's subjugation after the Fourth War. Tipu Sultan's refusal to accept it was the immediate casus belli. After his death, the Wodeyar dynasty was restored to Mysore but under a strict Subsidiary Alliance, effectively making it a British puppet state. This policy became the primary tool for British expansion and control over Indian states in the early 19th century.
