Dimitrija Čupovskiwas a Macedonian textbook writer and lexicographer. He was one of the founders of the Macedonian Literary Society, established in Saint Petersburg in 1902, and served as its president from 1902 to 1917. Čupovski was also the author of a large number of articles and official documents, publisher of the printed bulletin of the Macedonian Colony, and organiser of several Macedonian associations. He wrote verse both in Russian and Macedonian. He also produced the first Macedonian-Russian dictionary, worked on a Macedonian grammar and an encyclopaedic monograph on Macedonia and the Macedonians. He also drew up an ethnic and geographical map of Macedonia.In the period 1913–1914, Čupovski published the newspaper "Македонскi Голосъ" (Macedonian Voice) in which he and fellow members of the Petersburg Macedonian Colony promoted the existence of a separate Macedonian people which is different from the Greeks, Bulgarians and Serbs, and were struggling to popularize the idea for an independent Macedonian state. After the First World War and the October Revolution in Russia, the political activity of Čupovski ceased. He is considered one of the most prominent ethnic Macedonians in history and one of the most important actors of the ethnic Macedonian awakening.
