In ancient Rome, clients were citizens of the lower ranks who chose a patron from the higher classes, whose duty it was to advise and assist them, particularly in legal cases, and in general to protect them. The clients, on the other hand, were obliged to portion the daughters of the patron if he had not sufficient fortune; to follow him to the wars; to vote for him if he was candidate for an office, etc. This relation continued until the time of the emperors.
