Evidence of human habitation dates back 800,000–1.2 million years, with significant developments in agriculture, pottery, and settlement during the Neolithic and Bronze Ages. In antiquity, Moldova’s location made it a crossroads for invasions by the Scythians, Goths, Huns, and other tribes, followed by periods of Roman and Byzantine control. The medieval Principality of Moldavia emerged in the 1350s, and was the medieval precursor of modern Moldova and Romania. It reached prominence under rulers like Stephen the Great before becoming a vassal state of the Ottoman Empire from 1538, until the 19th century.
