Explanation:

The original capital of the state of Kullu was at Jagatsukh where the early kings ruled for twelve generations. Raja Visudh Pal transferred the capital to Nagar and later Raja Jagat Singh transferred it to Sultanpur. The famous idol of Raghunath was brought from Ayodhya to Kullu during the reign of Raja Jagat Singh to remove a curse which a Brahmin had casted upon Jagat Singh. Jagat Singh put the idol on the throne, proclaimed himself to be merely the first servant of the temple, and the curse was removed. Since then, the Rajas of Kullu ruled the state in the name of Raghunath, who became the principal deity of the Kullu valley. With this incident Vaishnavism established itself in a land where Shaivism and Shaktism were the dominant denominations. During the period of the Mughal rule, Kullu was subject to the suzerainty of the Mughal emperors and used to pay tribute to them.
