The reputation for justice and benevolence which Kapura enjoyed induced many immigrants to settle in Kot Kapura which soon became a place of considerable importance. During his long life, Kapur Singh had the rare honour of serving Guru Har Rai and Guru Gobind Singh during their travels in his part of the country. It is said that he received the pdhulor rites of Sikh initiation at the hands of Guru Gobind Singh who bestowed upon him a sword and shield, still preserved in the family. In 1708, at the age of eighty, Kapur Singh was treacherously assassinated by his old rival `Isa Khan, a Manjh Rajput, with whom he had a longstanding feud and who, in turn, fell at the hands of his revengeful sons, Sukhia, Sema and Mukhia.
