Starting the first century CE, the district was part of the Kushan empire for at least 150 years. In the fourth century, Samudragupta conquered the region and the Guptas held it for the next two centuries. After the downfall of the Kingdom of Brahmapura, the Katyuris from Joshimath established their rule over most of Kumaon including the Bhabhar parts. Starting in the middle of the 10th century, however, their power began to decline and they were eclipsed by the Chand kings of Champawat. The Chand kings generally had friendly relations with the empires to their south, but were never under their direct political control. The Chand rulers fought many wars with the Garhwal kingdom to their west. In 1790, the Gorkhas overran Kumaon including Nainital district and held it for 24 years, until the British took it in 1814 during the Anglo-Nepalese War. The region came under direct British rule and was organised into Nainital district in 1891 as part of the United Provinces. In 1916, Govind Ballabh Pant and Har Govind Pant established the Kumaon Parishad to fight for the grassroots of Kumaoni people. After Independence, Nanital district became part of the state of Uttar Pradesh. In 2000, Nainital district was one of the districts separated to form the new state of Uttarakhand.
