From which general region of the Roman Empire did Aurelian emerge?

Aurelian emerged from the region of Illyria, which is located in the Balkan Peninsula. This area was significant in the Roman Empire, as it produced several emperors and military leaders. Aurelian, who ruled from 270 to 275 AD, is particularly known for his military successes and his efforts to stabilize the empire during a time of crisis known as the Third Century Crisis. His origins from Illyria are notable as this region was considered a part of the military backbone of the Roman Empire, contributing to its strength and resilience through various challenges. The other regions listed, while important in their own right, do not have a direct connection to Aurelian's background and rise to power.
