The University of Tartu (UT; Estonian: Tartu Ülikool, Latin: Universitas Tartuensis) is a university in the city of Tartu in Estonia. It is the national university of Estonia, and the only classical university in the country, and also the biggest and most prestigious university in Estonia. It was founded under the name of Academia Gustaviana in 1632 by Baron Johan Skytte, the Governor- General (1629–1634) of Swedish Livonia, Ingria and Karelia, with the required ratification provided by his long-time friend and student – from age 7 –, King Gustavus Adolphus, briefly before the king's death on 6 November in the Battle of Lützen (1632), during the Thirty Years' War (1618–1648).
