The Indian Rebellion of 1857 was a major uprising in India in 1857–58 against the rule of the British East India Company, which functioned as a sovereign power on behalf of the British Crown. The names of the rebellion are contested, as it can variously be described as the Sepoy Mutiny, the Indian Mutiny, the Great Rebellion, the Revolt of 1857, the Indian Insurrection, and the First War of Independence. The rebellion began on 10 May 1857 in the form of a mutiny of sepoys of the Company's army in the garrison town of Meerut, 40 mi (64 km) northeast of Delhi. It then erupted into other mutinies and civilian rebellions chiefly in the upper Gangetic plain and central India, though incidents of revolt also occurred farther north and east. The rebellion posed a military threat to British power in that region, and was contained only with the rebels' defeat in Gwalior on 20 June 1858. On 1 November 1858, the British granted amnesty to all rebels not involved in murder, though they did not declare the hostilities to have formally ended until 8 July 1859.
The Second Anglo-Sikh War was a military conflict between the Sikh Empire and the East India Company that took place in 1848 and 1849.

The 21st Lancers (Empress of India's) was a cavalry regiment of the British Army, raised in 1858 and amalgamated with the 17th Lancers in 1922 to form the 17th/21st Lancers. Perhaps its most famous engagement was the Battle of Omdurman, where Winston Churchill (then an officer of the 4th Hussars), rode with the unit.
The Battle of Chillianwala was fought in January 1849 during the Second Anglo-Sikh War in the Chillianwala region of Punjab, now part of modern-day Pakistan. The battle was one of the bloodiest fought by the British East India Company. Both armies held their positions at the end of the battle and both sides claimed victory. The battle was a strategic check to immediate British ambitions in India and a shock to British military prestige.
The Central India Campaign was one of the last series of actions in the Indian rebellion of 1857. The British Army and Bombay Army overcame a disunited collection of states in a single rapid campaign, although determined rebels continued a guerrilla campaign until the spring of 1859.

The regiment was raised in India in 1652 by the East India Company as the company's first non-native infantry regiment. Over the following two centuries, the regiment was involved in nearly all of the East India Company's conflicts which consolidated British rule over India. The Royal Bengal Fusiliers was transferred to the command of the British Army in 1862 following the Indian Mutiny of 1857 and the end of Company rule in India. Under the Childers Reforms it amalgamated with the 104th Regiment of Foot (Bengal Fusiliers) to form the Royal Munster Fusiliers in 1881.

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.
The 20th Lancers is an armoured regiment in the Armoured Corps of the Pakistan Army. It is considered to be the successor of the old 20th Lancers of the British Indian Army.

The 45th Rattray's Sikhs was an infantry regiment of the British Indian Army. They could trace their origins to the 1st Bengal Military Police Battalion raised in April 1856, at Lahore, by Captain Thomas Rattray originally consisting of a troop of 100 cavalry and 500 infantry. The initial class composition of the troops was 50% Sikhs and 50% Dogras, Rajputs and Mussulmans (Muslims) from the Punjab and the North-West Frontier. It is said that he went through the villages challenging men to wrestle with him on the condition that they had to join up. Whatever the case, the regiment was raised and trained and developed as an elite corps, which soon saw action in Bihar in the Sonthal 'parganas'. After sterling service in Bihar, Bengal and Assam, and during the 1857 Mutiny, the cavalry portion was eventually disbanded in 1864 and the infantry section was taken into the line of Bengal Native Infantry as the '45th Native Regiment of Infantry'.
