The history of Ukraine spans thousands of years, tracing its roots to the Pontic steppe—one of the key centers of the Chalcolithic and Bronze Ages, Indo-European migrations, and early horse domestication. In antiquity, the region was home to the Scythians, followed by the gradual expansion of Slavic tribes. The northern Black Sea coast saw the influence of Greek and Roman colonies, leaving a lasting cultural legacy. Over time, these diverse influences contributed to the development of early political and cultural structures.
Ukraine enters into written history with the establishment of the medieval state of Kievan Rus'. In Dnieper Ukraine, the tribe of Polans played a key role in the formation of the state, adopting the name Rus' by the 9th century. The term is believed to have connections to the Varangians, who contributed to the state's early political and military structure. By the 10th–11th centuries, Kievan Rus' had grown into one of the most powerful and culturally advanced states in Europe, reaching its golden age under Vladimir the Great and Yaroslav the Wise, who introduced Christianity and strengthened political institutions. However, internal conflicts among Kyivan rulers, along with increasing pressure from Turkic nomads in Southern Ukraine, gradually weakened the state.
