an officer in the Roman cavalry, who commanded a decuria, which was a body consisting of ten men.

There were certain provincial magistrates called decuriones municipales, who represented the Roman senate in free and corporate towns. As the name implies, they consisted of ten; and their duty was to watch over the interests of their fellow-citizens, and to increase the revenues of the commonwealth. Their court was called curia decurionum, and minor senatus; and their decrees, called decreta decurionum, were marked with two Ds at the top. They generally styled themselves civitatum patres curiales, and honorati municipiorum senatorum. They were elected with the same ceremonies as the Roman senators; they required to be at least twenty-five years of age, and to be possessed of a certain fixed income. The election took place in the kalends of March.
