Mercenaries were groups of people that pretty much had no loyalty to a single nation. The fought along with nations that paid them (roman empire in this case).
A mercenary is someone hired to temporarily serve in a foreign army, they are normally specialized fighters with a specific skill, for example, archery. Unlike an official soldier of an army, a mercenary doesn't serve for political interests but for money or any other personal interest.
In the Roman Empire, mercenaries were non-Roman citizens hired to fortify the Empire's borders from any external attack or offensive. If they served for 25 years, they were given citizenship and rewarded with a plot of land to farm in their retirement.
It shows us that in the medical times the churches held most power as the people were very religious this is important because it emphasise the political control to be by a church not democracy???
