Four Pillars of Nepal Bhasa (Newar: नेपाल भाषाया प्यंगः थां) are the four leaders who spearheaded the campaign to revive the Newar language and its literature during the repressive Rana regime, and guided its renaissance at the beginning of the 20th century. They produced literature at the risk of personal freedom and laid the foundation for the development of modern Nepal Bhasa. Their work marks the beginning of the Nepal Bhasa movement in Kathmandu, which has led to greater rights in education, the media and official recognition.
