History
After World War I, the map of Eastern Europe was radically changed, with a number of ethnic groups becoming independent for the first time. One country, Serbia, eventually became part of the Republic of Yugoslavia, which joined the Serbs, Croats, and Slovenes into one country. This, of course, forced considerable reorganization of their armed forces. Of course, Serbia has virtually no aircraft manufacturing industry, so the Yugoslavs were compelled to acquire airplanes of foreign manufacture, mainly those built in Germany, Austria-Hungary, France, Italy, and England. German and Austrian aircraft were usually acquired as reparations due to the Treaty of Versailles, while the British, French, and Italian types were purchased directly. World War I vintage types were used throughout the twenties, but newer types were acquired in the thirties.
