The Indian Army during British rule, also referred to as the British Indian Army, was the main military force of the British Indian Empire until 1947.^[1] It was responsible for the defence of both British India and the princely states, which could also have their own armies. As quoted in the Imperial Gazetteer of India, "The British Government has undertaken to protect the dominions of the Native princes from invasion and even from rebellion within: its army is organized for the defence not merely of British India, but of all possessions under the suzerainty of the King-Emperor."^[2] The Indian Army was an important part of the forces of the British Empire, in India and abroad, particularly during the First World War and the Second World War.

The term Indian Army appears to have been first used informally, as a collective description of the Presidency armies, which collectively comprised the Bengal Army, the Madras Army and the Bombay Army, of the Presidencies of British India, particularly after the Indian Rebellion. The first army officially called the Indian Army was raised by the government of India in 1895, existing alongside the three long-established presidency armies. In 1903 the Indian Army absorbed the three armies. The Indian Army should not be confused with the Army of India (1903–1947) which was the Indian Army plus the British Army in India (British units sent to India), which was later split into the Indian Army and the Pakistan Army.
