The Roman Empire showed a very distinct interest for the Red Sea area along all its history. This was due to the crucial role played by such region in both military and commercial Roman plans to expand its own influence in the East. The first echo of a military attempt to conquer the north eastern shores of Africa beyond Egypt dates back to the age of Augustus, but it is with Trajan that such project seems to reach a new level of coherence and strategic view. Under the latter, in fect, we have evidence for a climax in the Roman control over the area, which had important consequences on the history of the region for decades ahead.
