The history of Perugia goes back to the Roman Empire. However, major parts of the city have been destroyed, and rebuilt, because of many wars, and of earthquakes in the mid-19th century. In recent decades, the city has been known as a university town, with the University of Perugia (about 34,000 students), the University for Foreigners (5,000 students), and some smaller colleges, also. There are annual festivals and events: the Eurochocolate Festival (October), the Umbria Jazz Festival, and the International Journalism Festival (in April).
