the Gorkhali language became the court language, and Newar was replaced as the language of administration. However, Newar continued to remain in official use for a time as shown by the 1775 treaty with Tibet which was written in it. A few of the new rulers cultivated the language. Kings Prithvi Narayan Shah, Rana Bahadur and Rajendra Bikram Shah composed poetry and wrote plays in it. Newar suffered heavily under the repressive policy of the Rana dynasty (1846–1951 AD) when the regime attempted to wipe it out. In 1906, legal documents written in Newar were declared unenforceable, and any evidence in the language was declared null and void. The rulers forbade literature in Newar, and writers were sent to jail. In 1944, Buddhist monks who wrote in the language were expelled from the country. Moreover, hostility towards the language from neighbours grew following massive migration into the Kathmandu Valley leading to the indigenous Newars becoming a minority. During the period 1952 to 1991, the percentage of the valley population speaking Newar dropped from 74.95% to 43.93%. The Nepal Bhasa movement arose as an effort to save the language. Nepal Bhasa movement Newars have been fighting to save their language in the face of opposition from the government and hostile neighbours from the time of the repressive Rana regime till today. The movement arose against the suppression of the language that began with the rise of the Shah dynasty in 1768 AD, and intensified during the Rana regime (1846–1951) and Panchayat system (1960–1990). At various times, the government has forbidden literature in Newar, banned the official use and removed it from the media and the educational system. Opponents have even petitioned the Supreme Court to have its use barred. Activism has taken the form of publication of books and periodicals to public meets and protest rallies. Writers and language workers have been jailed or expelled from the country, and they have continued the movement abroad. The struggle for linguistic rights has sometimes combined with the movement for religious and political freedom in Nepal. Renaissance era The period between 1909 and 1941 is considered as the renaissance era of Newar. During this period, a few authors braved official disapproval and started writing, translating, educating and restructuring the language. Writers Nisthananda Bajracharya, Siddhidas Mahaju, Jagat Sundar Malla and Yogbir Singh Kansakar are honored as the Four Pillars of Nepal Bhasa. Shukraraj Shastri and
