From around 750 BC to 250 BC, the Scythians established a powerful kingdom that extended its influence over much of the Eurasian steppes, including the territories of modern-day Ukraine. The Scythian kingdom is well-known for its unique art, horse-riding culture, and its role as a dominant force in the region. Meanwhile, Greek colonists founded several cities on the northern shores of the Black Sea during the 6th century BC, including Tyras, Olbia, and Hermonassa. These cities became important trading hubs and cultural centers, remaining under Roman and later Byzantine control until the 6th century AD.
