Gorkha Kingdom

Gorkhā was a former kingdom in the confederation of 24 states known as Chaubisi rajya located in present-day western Nepal. The Kingdom of Gorkha extended from the Marshyangdi River in the west to the Trishuli River in the east, which separated it from the kingdoms of Lamjung and Nepal respectively. The inhabitants of Gorkha were known as Gorkhali.

Shah/Jha/Khan controlled whole area of Ganges and Brahmaputra basin or simply whole land between Himalayas and Vindhyas. Soon the empire divided into several kingdoms. Mughal Empire, Bengal and Gorakhpur formed after division.

From 1736, the Gorkhalis engaged in a campaign of expansion begun by King Nara Bhupal Shah, which was continued by his son, King Prithvi Narayan Shah and grandson Prince Bahadur Shah. Over the years, they conquered huge tracts of land to the east and west of Gorkha.

Among their conquests, the most important and valuable acquisition was the wealthy Newar confederacy of Nepal Mandala centered in the Kathmandu Valley. Starting in 1745, the Gorkhalis mounted a blockade in a bid to starve the population into submission, but the inhabitants held out.

The Newars appealed to the British East India Company for help, and in 1767, it sent an expedition under Captain Kinloch which ended in failure. The three Newar capitals of Kathmandu, Lalitpur and Bhaktapur fell to the Gorkhalis between 1768 and 1769. The Gorkhali king subsequently moved his capital to Kathmandu.

In 1788, the Gorkhalis turned their attention north and invaded Tibet. They seized the border towns of Kyirong and Kuti, and forced the Tibetans to pay an annual tribute. When the Tibetans stopped paying it, the Gorkhalis invaded Tibet again in 1791 and plundered the Tashilhunpo Monastery in Shigatse. This time the Chinese army came to Tibet's defence and advanced close to Kathmandu. The alarmed Gorkhalis appealed to the British East India Company for help, but they got none. Eventually, the Gorkhalis were forced to sign a peace treaty under which they had to pay tribute to Beijing every five years.
