When Britain colonized and expanded in South Asia, why didn't it leave Nepal alone?

First of all, when Britain colonized and expanded in South Asia, it did not let Nepal go at first. After conquering India, Britain also plans to conquer Nepal. 18 14, Britain used the border dispute between India and Nepal as an excuse to launch a large-scale attack on Nepal from east, west and south. In the Battle of Malone at 18 14, the Battle of Kalang at 18 16, and the Battle of Devata, Nepalese soldiers and civilians suffered heavy losses to the British army, with thousands of Nepalese people losing, while the British army lost more than 8,000 people. If we hit Kathmandu, the war will turn into guerrilla warfare, and the British army may give up all its efforts.

The war lasted for two years, and Nepal lost because of the disparity in numbers and equipment. 1865438+On March 4, 2006, Britain forced Nepal to sign the Zagury Treaty, which stipulated that about 1000 square kilometers of land in Terai Plain would be ceded to British India, and Britain set up a representative station of the Governor in Kathmandu, and Britain obtained various privileges in Nepal. ?

Secondly, British colonization was to obtain resources, but Nepal's terrain was high in the north and low in the south, with hilly territory, and the land above 1000 meters accounted for nearly half of the total area. There are many mountains in the east, west and north.

The Himalayan region in northern Nepal is 4877-8844 meters above sea level. There are 14 mountain peaks over 8000m above sea level in the world, 8 of which are in the Himalayan region on the border between China and Nepal. The central mountainous area accounts for 68% of Nepal's land area, and consists of Mahabukhara mountain system with the highest peak of 4,877 meters and relatively short autumn mountain system. ?

Finally, Nepal is a dependent country of China, and Britain does not want to destroy its relations with China for the time being. At that time, Emperor Jiaqing sent Sai Chong A to guard the border during the Qianlong period, but Sai Chong A made a request for mediation to Nepal and Britain without authorization, demanding a truce between the two countries. The British were afraid of interference from the Qing Dynasty. ?
