Sarmenia refers to an ancient region located in Eastern Europe, primarily associated with the Sarmatians, a group of nomadic tribes. These tribes inhabited areas that are now part of modern-day Ukraine, Russia, and Kazakhstan. Sarmenia was known for its horse culture and warrior society, which played a significant role in the history of the region. The Sarmatians were known for their interactions with neighboring civilizations, including the Greeks and Romans. They were skilled horsemen and often engaged in trade and warfare. The decline of the Sarmatians began around the 4th century AD, leading to the eventual assimilation of their culture into other groups.
