The Sikh Empire was an empire mainly based in the Punjab region of the Indian subcontinent. It lasted from 1799, when Maharaja Ranjit Singh captured Lahore, until 1849, when the British East India Company defeated them in the Second Anglo-Sikh War. The empire stretched from Gilgit and Tibet in the north to the deserts of Sindh in the south and from the Khyber Pass in the west to the Sutlej in the east.
The empire had a diverse population of around 4.5 million in 1831, with Muslims being the majority at 70% and Sikhs at 6%. The British Empire annexed it, marking the end of independent Sikh rule in the Indian subcontinent.
The empire's origins trace back to the capture of Lahore from Zaman Shah Durrani, and Ranjit Singh became Maharaja in 1801. Ranjit successfully unified the Sikh misls and expelled much of the Durrani Empire remnants in Punjab. He modernized the Sikh army with European-style tactics and weaponry, and incorporated European officers. However, after his death, internal divisions and political mismanagement weakened the empire. The British East India Company took advantage, and in 1849, the Sikh Empire fell after losing the Second Anglo-Sikh War.

The Sikh Empire officially started in 1801, when Ranjit Singh of the Sukerchakia Misl coronated himself as a Maharaja in his new capital city of Lahore. He would gradually annex all the other rival Misls of the Sikh Confederacy by 1813. The leaders of these Misls (including Ranjit Singh) were usually from established Jat families with a long history in Sikh traditions.
Ranjit also subdued most of the local Punjabi Muslim polities. In some cases, Ranjit incorporated Muslims into his court. However, some discriminatory policies against Muslims were also enforced in parts of the empire.
Hari Singh Nalwa served as the Commander-in-Chief of the Sikh Khalsa Army from 1825 to 1837. He played a key role in conquering various regions and securing the Koh-i-Noor diamond. Nalwa expanded the empire's frontier to the Indus River, and at the time of his death, the western boundary was the Khyber Pass.
Ranjit Singh had modernized the Sikh army according to European standards. The British had recognized this earlier, and thus had chosen to sign the Treaty of Amritsar rather than risk direct confrontation. With the death of Ranjit, the empire significantly weakened due to the Brahmin-Dogra and Sandhawalia factions. Ranjit's successors (Kharak, Nau Nihal, Sher, and Duleep Singh) were all quickly deposed or killed. This division encouraged the British to invade.
Some of the battles of the Anglo-Sikh wars, most famously the Battle of Chillianwala, are seen as pyrrhic victories for the British, enabled primarily by betrayals from Sikh generals rather than incompetence from the soldiers. Ultimately, the empire was annexed into the British Raj.

It is obvious that their leadership was largely in Jaț hands and eventually it was a Jaț misldār, Raňjīt Siṅgh, who secured total ascendancy. Individual chieftains such as Jassā Siṅgh Kalāl (later known as Jassā Siṅgh Ahlūwālīā) and his namesake Jassā Siṅgh Rāmgaṛhiā represent leadership derived from lower-status groups, but do not disturb the dominant pattern.
In addition to the masjid's use as a site for military storage, stables for the cavalry horses, and barracks for soldiers, parts of it were also used as storage for powder magazines.
TEJ SINGH: After the death of Maharaja Ranjit Singh in 1839 AD, the Sikh empire quickly disintegrated largely because of the palace conspiracies and the role played by Dogra-Brahmins occupying high positions in the court. One of these Dogra-Brahmins was Tej Singh son of Nidhe Misr who had risen to the post of the Commander-in-Chief of the Sikh forces. The first Anglo-Sikh War in 1845-46 AD was lost among other things because Tej Singh deliberately directed the Sikh forces to advance towards those targets where they could easily fall into the enemy's trap. According to J.D Cunningham, he was in league with the British. Tej Singh died in 1862 AD.
