Year 443 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Macerinus and Barbatus (or, less frequently, year 311 Ab urbe condita). The denomination 443 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
No consuls are elected in Rome, but rather military tribunes with consular power are appointed in their stead. While only patricians could be consuls, some military tribunes were plebeians. These positions had responsibility for the census, a vital function in the financial administration of Rome. So to stop the plebeians from possibly gaining control of the census, the patricians remove from the consuls and tribunes the right to take the census, and rather entrust it to two magistrates, called censores who were to be chosen exclusively from the patricians in Rome.
