Explanation:

Nainital has historically been a part of the Kumaon region. After the fall of Katyuri Dynasty in 10th century, Kumaon was divided into several small princely states, and the region around Nainital was under various branches of a Khasiya family. The first dynasty to achieve consolidated dominance over Kumaon after the Katyuris was the Chand dynasty, but it took many centuries and Nainital and its surroundings were one of the last areas to be absorbed. Trilok Chand had built a fort at Bhimtal in the thirteenth century, But at that time, Nainital itself was not under the Chand rule, and was situated near the western border of the Kingdom. During the reign of Udyan Chand, the western boundary of the Chand kingdom extended upto the Koshi and Suyal rivers, but Ramgarh and Kota were still under the former Khasia rule. Kirat Chand, who ruled from 1488 to 1503 was finally able to establish authority over Nainital and the surrounding region. The Khasia chiefs made an attempt to regain their independence in 1560, when they enjoyed a brief moment of success under the leadership of a Khasiya of Ramgarh, but were later subdued with ruthlessness by Balo Kalyan Chand.
