public had important role in the unification of Nepal give six agreements to prove this statement

The unification of Nepal officially began in 1743 AD (1799 BS) after King Prithvi Narayan Shah of Gorkha launched an aggressive annexation campaign seeking to broaden his own kingdom's borders. After conquering the Nepal Mandala, which consisted of the three separate city-states of the Kathmandu Valley, Kathmandu, Lalitpur and Bhaktapur, Shah moved his hilly capital in Gorkha to the fertile and wealthy city of Kathmandu and adopted the name Nepal for the entire Gorkha Empire.[1]

The Shah dynasty would go on to unite the various warring kingdoms that once occupied parts of present-day Nepal into a nation-state that stretched up to the Sutlej River in the west and Sikkim-Jalpaiguri in the east.[1][2] Before usage by the Gorkha Empire, the Kathmandu Valley was known as Nepal after the Nepal Mandala, the region's Nepal Bhasa name.
