Burebista (Ancient Greek: Βυρεβίστας, Βοιρεβίστας) was the king of the Getae and Dacian tribes from 82/61 BC to 45/44 BC. He was the first king who successfully unified the tribes of the Dacian kingdom, which comprised the area located between the Danube, Tisza, and Dniester rivers, and modern day Romania and Moldova.
This in turn made him an enemy to Caesar, who decided to start a campaign against Dacia. This plan fell through in 44 BC when Caesar was assassinated. Burebista himself was assassinated in a plot by the Dacian aristocracy at around the same time.
