The conflict with Nepal began in the 17th century when the Gurkhas, a warrior people from Nepal, invaded Sikkim. The Gurkhas were eventually defeated, but the conflict continued for many years. In the 18th century, Sikkim also faced conflict with Bhutan. The Bhutanese invaded Sikkim in 1772 and occupied the country for several years. Sikkim was eventually able to regain its independence, but the conflict with Bhutan continued for many years.

In the 19th century, Sikkim faced conflict with Tibet. The Tibetans invaded Sikkim in 1828 and occupied the country for several years. Sikkim was eventually able to regain its independence, but the conflict with Tibet continued for many years.
