Military history of India

The earliest known reference to armies in what today is India are millennia ago in the Vedas and the epics Ramayana and Mahabaratha. From the ancient period to the 19th century, a succession of powerful dynasties and empires came to be and some were challenged by lesser Indian rulers who also struggled for land and power through warring. The British colonised India during the 19th century.

The predecessors to the contemporary Army of India were many: the sepoy regiments, native cavalry, irregular horse and Indian sapper and miner companies raised by the three British presidencies. The Army of India was raised under the British Raj in the 19th century by taking the erstwhile presidency armies, merging them, and bringing them under the Crown. The British Indian Army fought in both World Wars.

The armed forces succeeded the military of British India following India's independence in 1947. After World War II, many of the wartime troops were discharged and units disbanded. The reduced armed forces were partitioned between India and Pakistan. The Indian armed forces fought in all three wars against Pakistan and a war with the People's Republic of China. India also fought in the Kargil War with Pakistan in 1999, the highest altitude mountain warfare in history. The Indian Armed Forces have participated in several United Nations peacekeeping operations and are presently the second largest contributor of troops to the peacekeeping force.
