In the 1990s, efforts were launched in the Republic of Sakha (Yakutia) in the Russian Federation to support the revival of Sakha (Yakut) language education. This interdisciplinary study examines the evolution of school-based Sakha language education in the city of Yakutsk over a 25-year period beginning with the launching of the first reforms in the 1990s. Language education reform in the capital city has been shaped by a dynamic interplay between federal, regional, and local factors. Grassroots social and cultural activism continues to play a key role in school-based language revitalization in Yakutsk, influencing how policies have been received and implemented at the local level. Local community stakeholders are working together to counteract federal education policies, which direct school resources away from minority language education. This case study shows that the Sakha (Yakut) language revival has taken root in the capital city, and it provides important evidence that civic activism continues to develop in urban areas of the republic.
