Patricianship, the quality of belonging to a patriciate, began in the ancient world, where cities such as Ancient Rome had a social class of patrician families, whose members were initially the only people allowed to exercise many political functions. In the rise of European towns in the 12th and 13th centuries, the patriciate, a limited group of families with a special constitutional position, in Henri Pirenne's view, was the motive force. In 19th century Central Europe, the term had become synonymous with the upper Bourgeoisie and cannot be interchanged with the medieval patriciate in Central Europe. In the maritime republics of the Italian Peninsula as well as in German-speaking parts of Europe, the patricians were as a matter of fact the ruling body of the medieval town. Particularly in Italy, they were part of the nobility.

The patricians were originally a group of ruling class families in ancient Rome. The distinction was highly significant in the Roman Kingdom and the early Republic, but its relevance waned after the Conflict of the Orders. By the time of the late Republic and Empire, membership in the patriciate was of only nominal significance. The social structure of ancient Rome revolved around the distinction between the patricians and the plebeians. The status of patricians gave them more political power than the plebeians, but the relationship between the groups eventually caused the Conflict of the Orders. This time period resulted in changing of the social structure of ancient Rome.
