The early schools for Alaska Natives were mostly church-run schools of the Russian Orthodox missions in Russian-controlled Alaska (1799–1867), and, after 1890, the Jesuits and Moravians, allowed the use of the Alaska Native languages in instruction in schools. However, in the 1880s, Presbyterian missionary Sheldon Jackson (1834–1909) began a policy of prohibiting Native languages in the mission schools he managed. When he became United States Commissioner of Education, he proposed a policy of prohibition of indigenous language use in all Alaskan schools. This policy came into full force by about 1910. From that time period until the passage of the Bilingual Education Act in 1968, children in Alaskan schools suffered severe treatment for speaking their Native languages in schools.
