During the Indian Rebellion of 1857, and as a part of the Siege of Delhi, the Battle of Najafgarh took place on 25 August 1857 between Indian rebels and British Raj soldiers. Approximately 800 people were killed. After the defeat of the Mughal troops in 1857, Delhi came under the control of the British Empire in 1858. Najafgarh became a part of Delhi district of the Delhi Division of Punjab Province. Delhi was transferred from the North-Western Provinces (later the United Provinces) to Punjab by the British Government in 1859.
