I am wanting to write a alternative history based around a Roman Empire that stopped expanding, and withdrew to a smaller land after the loss at Teutoburg and was wondering what land they controled in 9AD. And yes i do know about r/historicalwhatif, i just want to know what they controlled at that time so i can explore myself what would happen to those places if Rome up and left.
Teutoburg, if anything, just dissuaded the Romans from going further. Rome lost only prestige after the defeat, something which they could almost make up for since they went back into Germania and subdued many Germanic tribes. There are stories of these new legions going through the battlefield and finding all the bones and armor of their comrades religiously placed around the forest and the field. By 9 AD, Rome under Augustus had expanded enormously. The controlled all of modern day France (Gaul) and Hispania, Italy (obviously), Greece, Pannonia (Austria), major Mediterranean islands, most of Turkey, a strong foothold in the middle east (had Jerusalem), Egypt and North Africa up to Carthage.
