Trajan's first Dacian war. 101 A.D. Emperor Trajan, the heralded new Caesar of the Roman Empire, seeks to reverse fifteen years of humiliating losses for Rome in wars against Dacia and its brilliant military leader King Decebal. To punish Dacia and Decebal, Trajan launches an invasion of Dacia with the largest army ever assembled in the history of Rome. Decebal And Trajan is the story of the middle years (100 – 102 AD) of the Roman – Dacian wars, which are also often called Trajan's First Dacian War. It is told from the point of view of King Decebal and the Dacian people fighting for their freedom and survival, and also from the point of view of Emperor Trajan fighting to assert Rome’s power and restore Rome’s pride and honor. The story of Decebal and Trajan is an epic clash of towering personalities and brutal military conflicts that would decide the fate of two nations.
