Second Anglo-Sikh War in the context of "Sikh Empire"

Company rule in India (also known as the Company Raj, from Hindi rāj, lit. 'rule') refers to regions of the Indian subcontinent under the control of the British East India Company (EIC). The EIC, founded in 1600, established its first trading post in India in 1612, and gradually expanded its presence in the region over the following decades. During the Seven Years' War, the East India Company began a process of rapid expansion in India, which resulted in most of the subcontinent falling under its rule by 1857, when the Indian Rebellion of 1857 broke out. After the rebellion was suppressed, the Government of India Act 1858 resulted in the EIC's territories in India being administered by the Crown instead. The India Office managed the EIC's former territories, which became known as the British Raj.

The range of dates is taken to have commenced either in 1757 after the Battle of Plassey, when the Nawab of Bengal Siraj ud-Daulah was defeated and replaced with Mir Jafar, who had the support of the East India Company; or in 1765, when the Company was granted the diwani, or the right to collect revenue, in Bengal and Bihar; or in 1773, when the Company abolished local rule (Nizamat) in Bengal and established a capital in Calcutta, appointed its first Governor-General of Fort William, Warren Hastings, and became directly involved in governance. The East India Company significantly expanded its influence throughout the Indian subcontinent after the Anglo-Mysore Wars, Anglo-Maratha Wars, and Anglo-Sikh Wars. Lord William Bentinck became the first Governor General of India in 1834 under the Government of India Act 1833.

The presidency armies were the armies of the three presidencies of the East India Company's rule in India, later the forces of the British Crown in India, composed primarily of Indian sepoys. The presidency armies were named after the presidencies: the Bengal Army, the Madras Army and the Bombay Army. Initially, only Europeans served as commissioned or non-commissioned officers. In time, Indian Army units were garrisoned from Peshawar in the north, to Sind in the west, and to Rangoon in the east. The army was engaged in the wars to extend British control in India (the Mysore, Maratha and Sikh wars) and beyond (the Burma, Afghan, First and Second Opium Wars, and the Expedition to Abyssinia).

The presidency armies, like the presidencies themselves, belonged to the Company until the Indian Rebellion of 1857, when the Crown took over the Company and its three armies. In 1895, the three presidency armies were merged into a united Indian Army.

The Punjab Province, officially the Province of the Punjab, was a province of British India, with its capital in Lahore and summer capitals in Murree and Simla. At its greatest extent, it stretched from the Khyber Pass to Delhi; and from the Babusar Pass and the borders of Tibet to the borders of Sind. Established in 1849 following Punjab's annexation, the province was partitioned in 1947 into West and East Punjab; and incorporated into Pakistan and India, respectively.

Most of the Punjab region was annexed by the East India Company on 29 March 1849 following the company's victory against the Sikh Empire's army at the battle of Gujrat in northern Punjab, a month prior. The Punjab was the last major region of the Indian subcontinent to fall to British imperialism.

Amb (Urdu, Hindko: امب) was a princely state within the Hazara Tribal Agency of North-West Frontier Province, British India, ruled by the Tanoli tribe. Together with the neighbouring estate of Phulra, the tract was known as "Feudal Tanawal". Its total area was 203 sq mi (530 km) while population was 48,656 in 1951. The Nawab of Amb Muhammad Farid Khan acceded to Pakistan after the independence of Pakistan in 1947. Today Amb is a part of Mansehra District of Hazara Division.

Amb came under the British suzerainty after the Second Anglo-Sikh War, with Mir Jehandad Khan providing much assistance to the East India Company against the Sikhs. The Amb Nawabs also provided military services to the British Empire in the Second Anglo-Afghan War. At the end of December 1947, the Nawab of Amb acceded to Pakistan while retaining internal self-government. Amb continued as a princely state of Pakistan until 1969, when it was incorporated into the North West Frontier Province (now Khyber Pakhtunkhwa).

The Battle of Gujrat was a decisive battle in the Second Anglo-Sikh War, fought on 21 February 1849, between the forces of the East India Company, and a Sikh army in rebellion against the company's control of the Sikh Empire, represented by the child Maharaja Duleep Singh who was in British custody in Lahore. The Sikh army was defeated by the British regular and Bengal Army forces of the British East India Company. After it capitulated a few days later, the Punjab was annexed to the East India Company's territories and Duleep Singh was deposed.

Field Marshal Colin Campbell, 1st Baron Clyde, GCB, KSI (20 October 1792 – 14 August 1863) was a British Army officer. After serving in the Peninsular War and the War of 1812, he commanded the 98th Regiment of Foot during the First Opium War and then commanded a brigade during the Second Anglo-Sikh War. He went on to command the Highland Brigade at the Battle of Alma and with his "thin red line of Highlanders" he repulsed the Russian attack on Balaclava during the Crimean War. At an early stage of the Indian Mutiny, he became Commander-in-Chief, India and, in that role, he relieved and then evacuated Lucknow and, after attacking and decisively defeating Tatya Tope at the Second Battle of Cawnpore, captured Lucknow again. Whilst still commander-in-chief he dealt with the "White Mutiny" among East India Company troops, and organised the army sent east in the Second Opium War.
