In June 1925, General Theodoros Pangalos launched a coup and ruled as a dictator for a year until a counter-coup by another General, Georgios Kondylis, unseated him and restored the Republic. In the meantime, Pangalos managed to embroil Greece in a short-lived war with Bulgaria precipitated by the Incident at Petrich and make unacceptable concessions in Thessaloniki and its hinterland to Yugoslavia in an effort to gain its support for his revanchist policies against Turkey.
