Decurions were drawn from the curiales class, which was made up of the wealthy middle class citizens of a town society. Decurions were the most powerful political figures at the local level. They were responsible for public contracts, religious rituals, entertainment, and ensuring order. Perhaps most importantly to the imperial government, they also supervised local tax collection.
