Jassa Singh was born in 1723 at Ichogil near Lahore into a family of Tarkhan carpenters. His father Bhagwan Singh had fought with Banda Singh. As a young man he served Adina Beg, the Mughal faujdar of Jalandhar, but in 1748, when Sikhs were besieged in the Ram Rauni fort at Amritsar, he changed sides and helped save them.
He rebuilt the fort, which was renamed Ramgarh, and his misl became the Ramgarhia misl. He was famous for his daring: in 1783 he raided as far as Delhi and carried off four guns and a slab of stone from the Mughal palace, which is still kept at the Ramgarhia Bunga in Amritsar. The towers of the Ramgarhia Bunga beside the Harmandir Sahib are his work.
He spent years in exile across the Sutlej after quarrels with the Kanhaiya and Ahluwalia misls, but returned and ruled his lands until he died in 1803. His name was taken by the Ramgarhia community of Sikh craftsmen, which spread across the world.
