When did Transylvania become part of the Habsburg 's Austrian empire ?
During this period , also called the Phanariot Epoch , the Romanian lands were characterised by the slow disappearance of the feudal system and the distinguishment of some rulers like Vasile Lupu and Dimitrie Cantemir in Moldavia , Matei Basarab and Constantin Brâncoveanu in Wallachia , and Gabriel Bethlen in Transylvania .
