List of battles involving the Sikh Empire
The Sikh Empire (1799 – 1849 CE) was established by Maharaja Ranjit Singh. Throughout its history, it fought various adversaries including the Durrani Empire of Afghanistan and the British East India Company.
Background
The Sikhs first raised their weapons against the Mughal Empire under Guru Hargobind. Shri Guru Hargobind Ji was son of the 5th Shri Guru Arjan Dev Ji who was executed by the Mughal ruler Jahangir. After his father's death, Shri Guru Hargobind Ji added the martial element to Sikhism which was until then a religion mainly focused on Spirituality. But at this point the need for self defence was felt. Hence Shri Guru Hargobind Ji started recruiting an army which he called "Risaldari", after training his men in cavalry and Sikh Martial Arts. He adopted Royal symbols like wearing "kalgidhari turban" and keeping bodyguards. Along with that he asked his followers to gift him horses and weaponry instead of anything else. So the 6th Guru at one point managed to command 700 cavalry and with this might his Risaldari fought several small scale battles in 1620s and 1630s against Shahjahan's forces and some other warlords in Poadh and Majha. The tenth and the last Guru, Guru Gobind Singh organized Sikhs into a military sect called Khalsa (means "pure"), in 1699, against the Mughal emperor Aurangzeb. Before his death in 1708, he sent Banda Singh Bahadur to lead the Sikhs of Punjab. Banda Singh Bahadur through his outstanding leadership skills weakened the Mughal grasp over India. But he was later captured and beheaded in Delhi in 1716, during the reign of Farrukhsiyar.
Thereafter, Sikhs were divided into Misls. In 1738, Nadir Shah of the Afsharid dynasty attacked India and looted Delhi. The Mughals were never able to recover their power in the Punjab. Later, the Punjab was subject to constant invasions of Ahmad Shah Durrani of Afghanistan.
The Afghans led numerous campaigns to re-capture Lahore but ultimately had to return to Pashtun territories due to internal strife. After Ahmad Shah's final invasion of the Punjab in 1767, he left Lahore which was re-captured by the Sikhs. For more than three decades, Sikhs consolidated their power in areas of the Punjab, though facing repeated invasion attempts from other Afghan emperors such as Timur Shah Durrani, and Zaman Shah Durrani. The decisive moment came in 1790, when Ranjit Singh of Sukerchakia Misl became Misldar. He started uniting Misls and finally took Lahore in 1799. His coronation on 12 April 1801 marked the beginning of the Sikh Empire, which went on to conquer the whole Punjab, Kangra, parts of Kashmir and briefly, the city of Peshawar.
