The Jagiellonian University (Polish: Uniwersytet Jagielloński, often shortened to UJ; historical names: Latin: Studium Generale, University of Krakow, Kraków Academy, The Main Crown School, Main School of Kraków) was established in 1364 by Casimir III the Great in Kazimierz (now part of Kraków). It is the oldest university in Poland, the second oldest university in Central Europe and one of the oldest universities in the world. In 1817, the university was renamed Jagiellonian University to commemorate Poland's Jagiellonian dynasty, which revived the University of Krakow after it fell upon hard times in the 17th and 18th centuries. In 2006, The Times Higher Education Supplement ranked Jagiellonian University as Poland's top university. In the mid-14th century, King Casimir III of Poland realized that the nation needed a class of educated people, especially lawyers, who could codify the country's laws and administer the courts and offices. His efforts to found an institution of higher learning in Poland were rewarded when Pope Urban V granted him permission to set up an academy in Krakow.
