Trajan is best known for his annexation of Dacia, but he also annexed the Nabataean Kingdom of Arabia in 106-107 CE upon the death of King Rabbel II Soter. Nabataea was the site of the convergence of several trade routes from India and southern Arabia and thus the source of popular goods like cinnamon, frankincense, and myrrh. The exact manner of the annexation is unknown, however by 107 it is clear that Roman legions were stationed around Petra and Bostra. This achievement is celebrated on the reverse with symbols typical of the region. Andrew Carroll 2011.
