Original sentence: Even today, the Greek government denies their existence as a national minority.Greece adopted strongly repressive policies towards the Slav population of Macedonian and Bulgarian origin in its northern regions.Greeks were resettled in the region in two occasions, firstly following the Bulgarian loss of the Second Balkan War when Bulgaria and Greece mutually deported their populations (1913), and secondly in 1923 as a result of the population exchange with Turkey that followed the Greek military defeat in Asia minor.Those that inhabited northeastern Greece were expelled.Those that stayed in northwestern Greece were regarded as potentially disloyal "Slavophone Greeks" and came under severe pressure, with restrictions on their movements, cultural activities and political rights; many were forced to emigrate, for the most part to Canada, Australia, USA and other eastern European countries
Edited sentence: A second population exchange with Turkey followed the Greek military defeat in Asia minor.After Bulgaria's siding with the Axis forces and the defeat of the Nazis in WWII, all Slavs in Greece were regarded as a Bulgarian minority and came under severe pressure, with restrictions on their movements, cultural activities and political rights; many were forced to emigrate, for the most part to Canada, Australia, USA and other eastern European countries.Greeks were resettled in the region following the Bulgarian loss of the Second Balkan War  when Bulgaria deported its Greeks, which it viewd as potentially disloyal, and Greece deported it Bulgarians, in the first of a series of internationally sanctioned population exchanges in the region.Like all Balkan countries at the time, Greece adopted repressive policies towards the Slav population in its northern regions.Those that inhabited northeastern Greece were exchanged with Greeks from Yugoslavia and Bulgaria or later expelled by the the fascist Metaxas government.Today all Slavophone populations of Greece have the same legal rights and status with the rest of Greek citizens
