Carpatho-Ukraine (also known as Carpathian Ruthenia or Subcarpathian Rus’), a region on the eastern edge of the Carpathian Mountains inhabited largely by Rusyns, was part of the Kingdom of Hungary within the Austro-Hungarian Empire. After World War I, the region joined the new Czechoslovakia as an autonomous province, gaining limited self-administration. Amid the political chaos of 1938–1939, following the Munich Agreement, Carpatho-Ukraine declared full independence on 15 March 1939 under President Avgustyn Voloshyn. The new state survived only a single day: Hungary invaded immediately, annexing the territory with tacit support from Nazi Germany. After World War II, the Soviet Union absorbed the region into the Ukrainian SSR as Zakarpattia Oblast. With the dissolution of the USSR in 1991, it became part of independent Ukraine, retaining a distinct cultural identity rooted in Rusyn traditions, multiple languages, and its brief but symbolically important moment of statehood.
Czechoslovakia issued a 3-koruna stamp to commemorate the independent Republic of Carpatho-Ukraine. The stamp dates the 1st National Assembly scheduled for 2 March 1939, but it was postponed to a later date. 300,000 were sent to the Carpatho-Ukraine capital, Khust, but only some were used for postage, with a significant number being destroyed by the Hungarian military administration. The remaining 600,000 left in Prague were sold within 10 days.
