territory. Diurpaneus and his people defeated and decapitated Oppius Sabinus. When news of the defeat reached Rome, the citizens became fearful that the conquering enemy would invade and spread destruction further into the Empire. Because of this fear, Domitian was obliged to move with his entire army into Illyria and Moesia, the latter of which was now split into Upper and Lower regions. He ordered his commander Cornelius Fuscus to cross the Danube. The Dacians were pushed back across the Danube, but Fuscus suffered a crushing defeat when ambushed by "Diurpaneus". At this point, the probably elderly Duras seems to have ceded power to Decebalus. Duras' concession of leadership was made peacefully. He continued to live in one of the palaces in Sarmizegetusa while serving as an advisor to Decebalus. King Decebalus ruled the Dacians between AD 87 and 106. The frontiers of Decebal's Dacia were marked by the Tisa River to the west, by the trans-Carpathians to the north and by the Dniester River to the east. His name translates into "strong as ten men". When Trajan turned his attention to Dacia, it had been on the Roman agenda since before the days of Julius Caesar when a Roman army had been beaten at the Battle of Histria. From AD 85 to 89, the Dacians under Decebalus were engaged in two wars with the Romans. In AD 85, the Dacians had swarmed over the Danube and pillaged Moesia. In AD 87, the Roman troops sent by the Emperor Domitian against them under Cornelius Fuscus, were defeated and Cornelius Fuscus was killed by the Dacians by authority of their ruler, Diurpaneus. After this victory, Diurpaneus took the name of Decebalus, but the Romans were victorious in the Battle of Tapae in AD 88 and a truce was drawn up . The next year, AD 88, new Roman troops under Tettius Julianus, gained a significant advantage, but were obligated to make a humiliating peace following the defeat of Domitian by the Marcomanni, leaving the Dacians effectively independent. Decebalus was given the status of "king client to Rome", receiving military instructors, craftsmen and money from Rome. To increase the glory of his reign, restore the finances of Rome, and end a treaty perceived as humiliating, Trajan resolved on the conquest of Dacia, the capture of the famous Treasure of Decebalus, and control over the Dacian gold mines of Transylvania.
