Sepoy Mangal Pandey of the 34th Regiment, Bengal Native Infantry mutinies against the East India Company's rule in India and inspires the protracted Indian Rebellion of 1857, also known as the Sepoy Mutiny.

A sepoy was the designation given to an Indian infantryman armed with a musket in the armies of the the Mughal Empire and the British East India Company.

Mangal Pandey was an Indian soldier who played a key role in the events that led to the Indian Rebellion of 1857, which resulted in the dissolution of the East India Company and the beginning of the British Raj through the Government of India Act 1858. He was a sepoy in the 34th Regiment of the Bengal Native Infantry. In 1984, the Republic of India issued a postage stamp in his memory. His life and actions have also been portrayed in several Indian cinematic productions.

A regiment is a military unit. Its role and size varies markedly, depending on the country, service, or specialisation.

The regiments of Bengal Native Infantry, alongside the regiments of Bengal European Infantry, were the regular infantry components of the East India Company's Bengal Army from the raising of the first Native battalion in 1757 to the passing into law of the Government of India Act 1858. At this latter point control of the East India Company's Bengal Presidency passed to the British Government. The first locally recruited battalion was raised by the East India Company in 1757 and by the start of 1857 there were 74 regiments of Bengal Native Infantry in the Bengal Army. Following the Mutiny the Presidency armies came under the direct control of the United Kingdom Government and there was a widespread reorganisation of the Bengal Army that saw the Bengal Native Infantry regiments reduced to 45.
