The state came into being after the First World War in 1918 in the course of the disintegration of the Austro-Hungarian Monarchy from the lands of Bohemia, Moravia and Moravian Silesia, as well as the former Hungarian Slovakia. From 1948 on, the re-established state was communist and belonged to the Eastern Bloc. After the collapse of the USSR and the political upheaval, the separation into the two independent states Slovakia and the Czech Republic took place in 1993. The wine-growing regions of the two states had a common history. The foundation of viticulture is attributed to the Roman emperor Probus (232-282). From the 10th century onwards, viticulture reached a great flowering through donations to monasteries in Bohemia and Moravia (today's Czech Republic).
