Sarmatia was a region of the Eurasian steppe inhabited by the Sarmatians.
Maciej Miechowita (1457–1523) used "Sarmatia" for the Black Sea region and further divided it into Sarmatia Europea, which included East Central Europe, and Sarmatia Asiatica.
In modern times, geographers had various views on its extent:[2] Another part was Sarmatia Europea ("European Sarmatia"),[5] which was situated further west.
European Sarmatia largely corresponds to what was later known as Grand Duchy of Lithuania; later, Intermarium; and nowadays the Three Seas Initiative.
Sarmatia was present in most maps of the region from the time of Ptolemy until the end of the 18th century.
