Lithuanian is the official state language of Lithuania and is recognized as one of the official languages of the European Union. There are about 2.96 million native Lithuanian speakers in Lithuania and about 170,000 abroad. Lithuanian is a Baltic language, closely related to Latvian, although they are not mutually intelligible. It is written in the Roman script.
Lithuanian still retains many of the original features of the nominal morphology found in the common ancestors of the Indo-European languages, and has therefore been the focus of much study in the area of Indo-European linguistics. Studies in the field of comparative linguistics have shown it to be the most conservative living Indo-European language.
Lithuanian and other Baltic languages passed through Proto-Balto-Slavic stage, during which Baltic languages developed numerous exclusive and non-exclusive lexical, morphological, phonological and accentual isoglosses with Slavic languages, which represent their closest living Indo-European relative. Moreover, with Lithuanian being so archaic in phonology, Slavic words can often be deduced from Lithuanian by regular sound laws.
According to some glottochronological speculations the Eastern Baltic languages split from the Western Baltic ones between 400 AD and 600 AD. The differentiation between Lithuanian and Latvian started after 800 AD; for a long period they could be considered dialects of a single language. At a minimum, transitional dialects existed until the 14th or 15th century, and perhaps as late as the 17th century. Also, the 13th- and 14th-century occupation of the western part of the Daugava basin (closely coinciding with the territory of modern Latvia) by the German Sword Brethren had a significant influence on the languages’ independent development.
The earliest surviving written Lithuanian text is a translation dating from about 1503–1525 of the Lord’s Prayer, the Hail Mary and the Nicene Creed written in the Southern Aukštaitijan dialect. Printed books existed after 1547, but the level of literacy among Lithuanians was low through the 18th century and books were not commonly available. In 1864, following the January Uprising, Mikhail Muravyov, the Russian Governor General of Lithuania, banned the language in education and publishing, and barred use of the Latin alphabet altogether, although books printed in Lithuanian continued to be printed across the border in East Prussia and in the United States. Brought into the country by book smugglers despite the threat of stiff prison sentences, they helped fuel a growing nationalist sentiment that finally led to the lifting of the ban in 1904.
