Republic of Crimea had the aim to "end the teaching of Ukrainian" by "pressure on school administrations, teachers, parents, and children". Religion In 2013, the majority of the Crimean population adheres to the Orthodox Church, with the Crimean Tatars forming a Sunni Muslim minority, besides smaller Roman Catholic, Ukrainian Greek Catholic, Armenian Apostolic and Jewish minorities.
