the century - fighting unit

[antiochus]

The basic information is that the Centuriate Assembly was organized into 193 centuries based on wealth and age and directly correlates to the military organization of men by these same categories.

Livy's total is 194 centuries. He includes one century of capite censi. My forthcoming book will mathematically confirm for a 700 year period, Livy is correct.

The Tribal Assemby was also organized into tribes then centuries.

The Tribal Assembly had it origins in the levy system. This means the levy system developed into a political system. The reason for this development was it gave equality to all classes. Livy does make reference to a levy formula. The tribal assembly was introduced as Dionysius states in 494 BC, which coincides with the creation of the 21 tribe.

Then, we get back to that age-old question of "which came first, the chicken or the egg?" Did the Assembly organization into centuries come before or after the military organization into centuries? - that is something which goes back into Rome's more legendary past.

Both were part and parcel of the same organisation. They were both developed with a military and political function simultaneously.
