This article examines the reform of the comitia centuriata in the mid to late third century b.c.e. This involved demoting in voting order the six most prestigious cavalry centuries, distributing the centuries of the first class two per tribe, and assigning one tribe's iuniores to vote first as the centuria praerogatiua. The article argues that this gave more equitable representation to rich citizens from more distant parts of Roman territory, but still preserved the essential military character of the assembly by ensuring that the serving men voted first in any election for consuls and praetors.
