 This meant that the Romanian population of Transylvania was never directly represented in the Transylvanian Diet, which consisted of Hungarian nobles, German and Székely nobles (the Unio Trium Nationum).Moreover, in Medieval times, the Romanians were not allowed to reside within the walls of such Transylvanian cities as Sibiu ("Nagyszeben"/"Hermannstadt"), Brasov ("Brassó"/"Kronstadt") or Cluj ("Kolozsvár"/"Klausenburg").This led to extensive persecution against the under-represented Romanians.
