The Roman army was unique in many ways and to this day its organization is copied in many different variants. During the times of the greatest Roman conquests, under Emperor Trajan, the area controlled by his army ranged from Britain and Spain to Asia Minor and North Africa.
In total 27 legions stationed on Roman lands, so about 150,000 people. If so, it was possible to mobilize even more legions and reach about 300,000 soldiers. It should be noted that the legions were supported by a similar number of auxiliary troops.
The hostilities of the Roman army were gigantic. Among the largest are Trajan’s Dacian wars, fought in today’s Romania at the turn of the 1st and 2nd centuries CE. In the first of these wars, in the years 101-102, 150,000 people took part. soldiers, while in the second, in 105 CE, as many as 200,000.
