Medieval university is an institution of higher learning which was established during High Middle Ages period and is a corporation. The first European medieval institutions generally considered to be universities were established in Italy, France, and England in the late 11th and the 12th centuries for the study of arts, law, medicine, and theology. These universities evolved from much older schools and monasteries, and it is difficult to define the date at which they became true universities, although the lists of studia generalia for higher education in Europe held by the Vatican are a useful guide. "The word universitas originally applied only to the scholastic guild (or guilds) that is, the corporation of students and masters within the studium, and it was always modified, as universitas magistrorum, or universitas scholarium, or universitas magistrorum et scholarium. In the course of time, however, probably toward the latter part of the 14th century, the term began to be used by itself, with the exclusive meaning of a self-regulating community of teachers and scholars whose corporate existence had been recognized and sanctioned by civil or ecclesiastical authority."
