The University of Tartu (UT; , ) 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 its biggest and most prestigious university. 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 former student – from age 7 –, King Gustavus Adolphus, shortly before the king's death on 6 November in the Battle of Lützen (1632), during the Thirty Years' War (1618–1648).
