The history of the University of Bonn reflects the German history of the 19th and 20th century to a great extent: from the foundation in 1818 after the Rhineland became part of Prussia, to the involvement of its professors in the revolution of 1848/49, the "Princes' University" in the German empire, the difficult conditions during the occupation after 1918, the ideologisation and repression during National Socialism, up to the capital university of the "the Bonn Republic" and new forms of protest with the 1968 movement and the demonstrations against the NATO Double-Track Decision in the university's park "Hofgarten".
