Book excerpt: Three powerful empires - the Habsburg, the Ottoman and the Russian - spent the 18th and the first third of the 19th centuries fighting each other for power and influence in the Balkans. This is not, however, the only significant aspect of the complicated history of the European Southeast. The intellectual and economic currents that turned the 18th century into a key event in human civilisation were refracted through the prism of Balkan regionalism. The 130 years between Karlowitz and Adrianople were able to steer the Southeast back onto the rails of a "Common European History". The volume contains the proceedings of an international conference hosted by the Sofia University Faculty of History in October 2009.
