Decebalus was the last king of Dacia (present-day Romania), who fought three wars against the Roman Empire in the late 1st and early 2nd centuries AD. He had early success against Domitian, securing independence for Dacia. However, under Emperor Trajan, the Roman armies invaded and defeated Dacia. Decebalus remained as a client king but continued asserting independence, leading to a final overwhelming Roman invasion in 105 AD that destroyed the Dacian capital and absorbed the region into the Roman Empire. Decebalus committed suicide rather than be captured.
