- -20% mercenary upkeep costs
Mercenaries have existed for thousands of years but the earliest written record of them dates back to the 7th century BC, when Greek hoplites sought employment as bodyguards serving Pharaohs and Greek tyrants alike. Mercenaries became a great way to bolster troop numbers during times of war, something to which the Carthaginians resorted during their war with Rome. They exploited their trade links to recruit troops from the Iberian peninsula and the Balearic islands. The Romans were more sparing with their use of mercenaries, but acknowledged the shortcomings within the Legion, notably archers and cavalry, by making up for the lack with carefully chosen mercenary troops.
