Input: Question: Which group ruled the longest? Passage:In the decline and fall of the Mughal supremacy and the rise of the Sikh power this district saw its most stirring scenes. Some of the Sikh Gurus have been closely associated with the district. Guru Nanak, born in 1469 in the Lahore district, married in 1485 with Sulkhani, daughter of Mool Chand, a Khatri of Pakhoke (Dera Baba Nanak) in the Batala Tehsil. There is still a wall known as Jhoolana Mahal which swings in Gurdaspur. The Sikh Guru Hargobind refounded Sri Hargobindpur which had been formerly known by the name of Rahila. Banda Singh Bahadur, the disciple of Guru Gobind Singh used this district as a base to raid the country up to Lahore, the emperor Bahadur Shah conducted an expedition against him in 1711 but with only temporary effect. Banda Bahadar fought his last battle with the Mughal at Gurdas Nangal in the district and was captured. The history of the district then degenerates into an account of their struggles with the rival Ramgarhia Misl and Kanhaiya Misls for supremacy in this part of the Doab, the power of the former was broken in 1808 and of the latter in 1811.
