King Prithvi Narayan Shah, the last Gorkhali monarch, self-proclaimed the newly unified Kingdom of Nepal as Asal Hindustan ("Real Land of Hindus") due to North India being ruled by the Islamic Mughal rulers. The proclamation was done to enforce Hindu social code Dharmashastra over his reign and refer to his country as being inhabitable for Hindus. He also referred Northern India as Mughlan (Country of Mughals) and called the region infiltrated by Muslim foreigners.

After the Gorkhali conquest of Kathmandu valley, King Prithvi Narayan Shah expelled the Christian Capuchin missionaries from Patan and revisioned Nepal as Asal Hindustan ("real land of Hindus"). The Hindu Tagadharis, a Nepalese Hindu socio-religious group, were given the privileged status in the Nepalese capital thereafter. Since then Hinduisation became the significant policy of the Kingdom of Nepal. Professor Harka Gurung speculates that the presence of Islamic Mughal rule and Christian British rule in India had compelled the foundation of Brahmin Orthodoxy in Nepal for the purpose building a haven for Hindus in the Kingdom of Nepal.
