First Anglo-Mysore War: Background, Changing Alliances, Course of Conflict, and the Concluding Treaty of Madras ()

This clash between British ambitions and local Indian rulers made Southern India a center for heavy political fighting and military actions.

    • (i) The English East India Company, feeling confident after winning power in Bengal, believed its army could easily control other parts of India.
    • (ii) A major cause of the war was the agreement made in with the Nizam of Hyderabad. The Nizam gave the Northern Circars region to the English if they helped him fight Haidar Ali.
    • (iii) Haidar Ali was already dealing with other big political problems, including older fights with the nearby Nawab of Arcot and ongoing land disagreements with the powerful Marathas.
