ABECEDAR 1925, was a school book printed in 1925 by the Greek Government, for the Macedonian Minority that still lives in the Aegean part of Macedonia (the region that Greece occupied and annexed from Macedonia after the Balkan wars in 1913 with the Treaty of Bucharest). Back than the League of Nations (what we know today as United Nations), pressured Greece t respect the human rights of their minorities - because the official Greek censuses - clearly showed that Macedonians are living in their native country and that they need to respect them (https://history-from-macedonia.blogspot.com/2017/04/greek-report-mother-language-macedonian.html or this one https://imgur.com/gallery/ssyIjU6) . Obviously this as the last good will that Greek official have done toward human rights and Macedonian population which is still point of ethnic cleansing and assimilation) with the latest pressure for Macedonia to change it's constitutional name from Macedonia to North Macedonia (the south was annexed by Greece)..
