Roman Auxillia question

[cmacq]

During the 1st century A.D./B.C., what was the deciding factor on who was recruited into the legions and who was recruited into auxillia units. By this time period, most of the legions were recruited in the provinces and I know that citizenship was a defining factor on whether the draftee...

hope this helps.

Roman Legionary = the regular army; mandatory service for all adult males, age, citizen, class (landownership early, rank, placement, office). However, not all males were required to serve in the army.

01 Contubernium - 8 Men = an army section or two combat teams
10 Contubernia 1 Century - 80 Men = an over strength army platoon
02 Centuries 1 Maniple - 160 Men = an army company
03 Maniples 1 Cohort - 480 Men = an army battalion
10 Cohorts + 120 Horsemen + organic support = 1 Legion - 5240+/- Men and x number of Officers = an army brigade or an under strength army division (as cohorts grouped right, left, and center; possibly organized as regiments)

axillia = mercenary/irregular/native/foreign forces; specialized troops organized along native lines. noncitizen, cavalry, archers, light infantry, and heavy assault infantry.

The Constitutio Antoniniana didn't actually give citizenship to all adult males, it just opened it up to a larger group. Each year a very large number of people entered into Roman territory. I've seen an estimate of 100,000 new people, were required for labor/slaves alone, every year just to maintain the status quo in the late 1st century BC.


However, you didn't ask about Numeri and Cunei?
