Chronological overview of legions
|A Roman legion
was an infantry unit, which consisted of heavily armed soldiers,
equiped with shields, armor, helmets, spears and swords. In the early republic,
the strength of a legion was about 3,000 men; there were 4,800 legionaries
in the days of Julius
Caesar; the twenty-five legions that defended the empire during the
reign of Augustus
counted more than 5,000. They were the backbone of the Roman army. However,
in the third century, large cavalry units gradually superseded the legions.
There are two tables: the first
one describes the imperial legions and mentions where they were stationed,
the second describes the provinces
and mentions the legions. Go here
