SINGHPURIA (or FAIZULLAPURIA) MISL was founded by Kapur Singh, a Virk Jatt of the village of Kaleke, now in Sheikhupura district of Pakistan Punjab. The misl got its name from Faizullapur, a village in Amritsar district which Kapur Singh had wrested from its Muslim chief, Faizulla Khan, and, conquering the country around, given it the name of Singhpura. Kapur Singh was eleven years old at the time of Guru Gobind Singh's passing away. His physical courage and warlike spirit were valuable qualities in those days of high adventure. He soon gained a position of eminence among Sikhs then engaged in a desperate sruggle against the Mughal rulers. When in 173P3 Zakriya Khan, the Mughal governor of Lahore, decided to make peace with the Sikhs, he offered them a jagar and title of Nawab for their leader. The Khalsa chose with one voice Kapur Singh to receive the title. Nawab Kapur Singh now proceeded to restructuring the Sikh fighting force. The whole body of the Khalsa was formed into two sections, the Buddha Dal, army of the veterans, and the Taruna Dal, army of the young. The cstentewith the Mughals did not last long and, before the harvest of 1735, Zakariya Khan sent a force and occupied the jagzr. Nawab Kapur Singh and his band were driven away towards the Malva by Lakhpat Rai, the Hindu minister at the Mughal court at Lahore. During his sojourn in the Malva, Nawab Kapur Singh conquered the territory of Sunam and made it over to Ala Singh of Patiala.
He also attacked Sirhind and defeated the Mughal governor. Returning to Amritsar, he successfully routed, in 1736, the force led by Lakhpat Rai, killing two important faujdars, Jamal Khan and Tatar Khan, in the battle. With 2,000 followers Nawab Kapur Singh entered, in disguise, the city of Lahore with a view to capturing the governor, Zakariya Khan. Driven back, Nawab Kapur Singh proceeded towards Delhi, the imperial capital. He overran Faridabad, Balabhgarh and Gurgaon and laid contributions on JhaUar, Dojana and Pataudi. In 1748 at the time of the organization of the Dal Khalsa, a confederation of various misls, Nawab Kapur Singh handed over leadership of the Sikhs to Jassa Singh Ahluvalia and himself continued to guide the destinies of the newly formed Singhpuria house or misl. On his death in 1755, charge of the misl came into the hands of his nephew Khushhal Singh who made further territorial acquisitions. Capturing Jalandhar in 1759, he made it his capital, and seized the parganahs of Haibatpur and Patti from the Pathan chief of Kasur. At the time of the conquest of Sirhind by Sikhs in January 1764, he got Bharatgarh, Machhall, Ghanauli, Manauli and several other villages as his share of the booty. Khushhal Singh and Rija Amar Singh of Patiala took from the Nawab of Raikot 23 villages around Chhat and Banur which remained under their joint control for several years. The Singhpuria territory yielded annually two lakhs in the Bari Doab, one lakh in the Jalandhar Doab and one and a half lakh in the Sirhind province. Khushhal Singh died in 1795 and was succeeded by his son Buddh Singh. But like other sardars, Buddh Singh also succumbed to the rising power of Ranjit Singh who occupied his Bari Doab and Jalandhar Doab territories. He was forced to shift to his estates below the River Sutlej, with Manauli as his new headquarters. Buddh Singh died in 1816 leaving behind seven sons. The cis Sutlej remnants of the Singhpuria misl were eventually annexed by the British.
