Size of the Roman army
Republican period (509 - 31 BC)
At the death of Julius Caesar there were 37 legions in the whole Roman world, including 6 in Macedonia, 3 in Africa and 10 in the eastern provinces. We must not forget that these troops were extremely mobile, that their hiberna (winter quarters) were still rudimentary and little more than a "marching camp".
