The University of Wrocław has a rich history of more than three centuries. Founded by Leopold I Habsburg the university evolved from a modest school run by Jesuits into one of the biggest academic institutions in Poland. At the beginning of the 19th century the university had five Faculties: philosophy, catholic theology, evangelical theology, law and medicine. Later it was expanded by numerous sections, laboratories and a natural museum, which exists until today.After the Second World War a group of Polish professors, formerly from Lvov, started teaching and research activities at the University of Wrocław. Initially they created the Faculties of law and administration, arts, natural sciences, agriculture, veterinary, medicine, mathematics, physics and chemistry. Some of these Faculties were soon transformed into other universities.
