Estonians have strong ties to the Nordic countries today stemming from strong cultural and religious influences gained over centuries during Scandinavian colonization and settlement. This highly literate society places strong emphasis upon education, which is free and compulsory until age 16. The first book in Estonian was printed in 1525. About 20% of the population belongs to the following churches registered in Estonia: Estonian Evangelical Lutheran Church, Estonian Apostolic Orthodox Church, Estonian Orthodox Church subordinated to the Moscow Patriarchate, Baptist Church, Roman Catholic Church, and others.

From 1945-1989 the percentage of ethnic Estonians in Estonia dropped from 94% to 61%, caused primarily by the Soviet program promoting mass immigration of urban industrial workers from Russia, Ukraine, and Belarus, as well as by wartime emigration and Soviet premier Josif Stalin's mass deportations and executions.

Written with the Latin alphabet, Estonian is the language of the Estonian people and the official language of the country. One-third of the standard vocabulary is derived from adding suffixes to root words. The oldest known examples of written Estonian originate in 13th century chronicles. During the Soviet era, the Russian language was imposed for official use.
