The British Indian Army was the main military force in India until 1947. It was created in 1895 by merging the Bengal, Madras, and Bombay armies. Its job was to defend British India and the princely states. Sometimes it was called the Army of the Indian Empire.

Before 1858, the three Presidency armies were separate and tied to the East India Company. After the 1857 rebellion, the Crown took direct control. In the early 1900s the army was reorganized under Lord Kitchener. The three presidency armies were united into a single Indian Army, organized in four commands and later restructured into different “armies” and corps. The aim was to have a single, centralized force trained to fight on the North‑West Frontier, with internal security as a secondary duty.

The Indian Army fought in many major wars and campaigns. In World War I about 1.5 million Indian soldiers served, with units on the Western Front, in Africa, the Middle East, Mesopotamia, and elsewhere. Twelve Indian soldiers won the Victoria Cross in that war. Imperial Service Troops from Indian princely states also fought in places like the Sinai and Palestine.

During the interwar years, the army began to modernize and Indian officers started to take higher roles. The Indian Territorial Force was created in the 1920s as a part‑time volunteer reserve, and Indians began to receive full commissions as King’s Commissioned Indian Officers.

World War II saw even larger numbers. About 2.5 million Indian soldiers served, making it the largest all‑volunteer force in history at that time. Six corps and many divisions were formed, and Indian troops fought in every major theater. Roughly 87,000 Indian soldiers were killed, and 31 were awarded the Victoria Cross. Some Indian opponents of the British, including Subhas Chandra Bose’s Indian National Army (INA), fought with Japan against the Allies.

In 1947, when India and Pakistan became independent, the army was divided between the two new nations. Four Gurkha regiments joined the British Army, while the other six Gurkha regiments became part of the Indian Army. The partition reshaped the Indian Army to become the modern Indian Army, which kept much of the old organizational framework but was now under an independent government.

Recruitment over the years drew on many groups from the Indian subcontinent, including Sikhs, Rajputs, Punjabis, Gurkhas, and other communities. British officers and Indian officers shared ranks, with Indian officers gradually taking on more prominent roles.

In short, the British Indian Army grew from regional armies into a unified force that played a crucial role in both world wars and helped shape the military structure that India uses today.
