Decemviri (plural) is a Latin term meaning ten (decem) men (viri). The ancient Romans used it to designate any ten-man commission during the period of the Roman Republic (cf. Triumviri, Three Men). In English it is rendered as decemvirate. Different types of decemvirates included decemviri legibus scribundis consulari imperio (decemviri writing the law with consular power), decemviri litibus iudicandis (decemviri adjudging litigation) decemviri sacris faciundis (decemviri making sacrifices) and the distribution of public lands (agris dandis adsignandis). The singular, decemvir, is used to indicate a member of a decemvirate both in Latin and in English. In English decemvirs is used as a plural for this.
The setting up of this decemvirate occurred within the context of the two hundred-year Conflict of the Orders between the patrician order (the aristocracy) and the plebeian order (the commoners). The patricians had developed into the upper class by monopolising the priesthoods, which played an important part in the politics of archaic Rome and, in the Early Republic, the consulship (the office of the two annual elected heads of the Roman Republic and the army), and the seats of the (unelected) senate, the advisory body for the consuls. They were also large landowners. The form of labour exploitation during this archaic period was the nexum, which was what historians call debt bondage, bonded labour, or debt slavery. The debtor pledged his labour services as collateral for debt. Defaulting debtors were liable to have their labour bonded for life.
