The Punjab Regiment is an infantry regiment of the Pakistan Army. The regiment takes its name from the historic Punjab region, which is now divided into the Punjab province of Pakistan and the Indian states of Punjab, Haryana and Himachal Pradesh. It was raised in its current form in 1956, following the amalgamation of the 1st, 14th, 15th and 16th Punjab regiments that were inherited by the Dominion of Pakistan from the British Indian Army upon the Partition of India. Since then, the regiment has expanded in size to 63 battalions. It is the oldest regiment in the Pakistan Army, tracing its lineage to as far back as 1751, during the reign of the Mughal Empire. The regiment's battalions have a distinguished record of military service, spanning the rise and decline of British colonial rule in South Asia, both World War I and World War II, as well as post-independence Pakistan. Early history The Punjab Regiment of Pakistan traces its origins back to the Madras Army of the British East India Company. The senior-most battalion of the 1st Punjab Regiment (which existed separately before 1956) was raised in 1759 as the 3rd Battalion of Coast Sepoys, and became the oldest-surviving infantry battalion of the erstwhile British Indian Army. Their first major engagement saw a decisive victory at the Battle of Wandiwash in 1760, when the British East India Company, led by Sir Eyre Coote, effectively ended French colonial ambitions in South Asia. All of the regiment's battalions subsequently played an important role in the early military campaigns of the East India Company and were actively engaged in the wars against the French, the Kingdom of Mysore and the Maratha Empire. The numbers and titles of the battalions changed during the successive reorganizations of the Madras Presidency Army, the British Indian Army and the Indian Army during the 18th, 19th and 20th centuries. The names changed from Coast Sepoys to Carnatic Infantry, Madras Native Infantry, Punjabis and finally to the Punjab Regiment. After the Indian Rebellion of 1857, the new colonial administration applied the martial races concept, following which north Indian soldiers overwhelmingly supplanted the south Indians. The regiment was eventually renamed to the Punjab Regiment. British Raj Following the British Crown's takeover of rule over British India from the East India Company in 1858, the Punjab regiments played a role in numerous conflicts across the world involving the British Empire.
