The Gorkha Kingdom was a member of the Chaubisi rajya, a confederation of 24 states, located at the intersection of Himalayas and the Indian subcontinent. In 1743 CE, the kingdom began a campaign of military expansion, annexing several neighbors and becoming present-day Nepal. The Gorkha Kingdom extended to the Marshyangdi River in the west, forming its border with the Kingdom of Lamjung. To the east, the kingdom extended to the Trishuli River, forming its border with the Nepal Mandala. The Gorkha Kingdom was established in 1559 CE by Prince Dravya Shah, the second son of King Yasho Brahma Shah of Lamjung. The prince replaced the King Mansingh Khadka Magar who previously ruled the region.
