either 45 or 44BC. Death Burebista may have outlived Caesar for only a short time. In the same year Caesar was assassinated, Burebista was killed in a plot by the Dacian aristocracy, who saw a centralized state as leading to a reduction in their privileges. After his death, the Dacian kingdom dissolved, with the exception of the enclave around the Orăştie Mountains, while the rest became various smaller kingdoms. After Burebista's death, the kingdom was divided into four parts, to be ruled by the religious elite. By the time of Augustus Dacia had broken further into five parts. Dacia after Burebista In the time following Burebista's death, and between the rule of Domitian and the rule of Tiberius, Dacian activity was minimal. The Dacians were forced into a defensive state where their main activity was keeping the Romans out of Dacian territories. The regional factions that remained posed no substantial threat to the Roman empire, and Roman sources stop mentioning plans for Roman invasions during this time. Dacian power resurged during the reigns of Duraswho reigned 68–87ADand peaked during the reign of Decebaluswho reigned from 85/87-106AD. By this time the Dacian tribes had united once more, under the rule of Decebalus, and again posed a threat to Rome. Decebalus' reign saw nearly constant warfare between the Dacians and Roman administrations south of the Danube. Around 85AD raiding resumed in Moesia, Illyria, and Macedonia, culminating in the death of the Roman Governor of Moesia, Oppius Sabinius. In response, Domitian launched a campaign the same year under the command of the Praetorian Prefect Cornelius Fuscus. Domitian ignored Decebalus' offer of peace, an error which caused the Romans to suffer a disastrous defeat, losing not only Fuscus, but his forces and the Roman standards and war machines. A second expedition was launched in 88AD, this time under the command of Tettius Julianus. This second campaign was somewhat victorious as both sides suffered massive casualties in battle. However, revolts and defections forced Domitian to negotiate a hasty peace treaty with Decebalus in 89AD. This peace had benefits and costs to both sides: Rome had to pay financial tributes and provide technological assistance to Dacia; in exchange, Dacia effectively became a client kingdom of Rome, acting like a bulkhead to the empire by separating Rome from other warring tribes. This peace lasted for around a decade, until Trajan became emperor in 98AD. Immediately upon becoming
