Emperor Trajan’s victory at the Battle of Sarmizegetusa in 102 AD became the critical moment that changed the course of the First Dacian War. Trajan’s leadership and tactical genius combined with the disciplined strength of the Roman legions led to the defeat of King Decebalus’ Dacian forces. The fall of Sarmizegetusa as a major defensive stronghold allowed Dacia’s annexation by the Roman Empire.
Following his triumph, Trajan could issue a decree such as the one below, outlining the expectations for the Dacian people as they integrate into Roman civilization and fulfill their duties under Roman rule.
