The Estonian Constitution, adopted in 1992, states that “the preservation of the Estonian nation and culture through the ages” is one of the central aims of the Republic. The Constitution guarantees freedom of speech and self-expression, while the incitement of national, racial, religious or political hatred, violence or discrimination is prohibited. As to the cultural rights of national minorities, the Constitution refers to the Law on Cultural Autonomy of National Minorities (see, however, chapter 2.6). Right to education is guaranteed for everyone. An artist is guaranteed the inalienable right to his or her work, and the state has the obligation of protecting the rights of an author.
