During the 19th and 20th centuries there was a major dispute known as Greek language question, on whether the official language of Greece should be the archaic Katharevousa, created in the 19th century and used as the state and scholarly language, or the Dimotiki, the form of the Greek language which evolved naturally from Byzantine Greek and was the language of the people. The dispute was finally resolved in 1976, when Dimotiki was made the only official variation of the Greek language, and Katharevousa fell to disuse.
