2. The rise of the city introduced an entirely novel element into the historical process. As a result we find the historians among the first to study this phenomenon of human aggregation which culminated in the city. The historian is mainly interested in tracing the development of this new form of social life from the standpoint of structure and formal organization. The origin of the city has been traced, the ancient cities have been described, the Greek city-state, Rome, the rise of the medieval city, and its transformation into the modern city have found an important place in historical literature. The earlier studies are mainly political in nature. Only recently have historians devoted themselves to describing the new modes of life to which the city gave rise, and the interrelations between city and country. The city has been regarded chiefly as a political unit. The name “city” was given to a settlement because it had achieved a certain degree of political autonomy from the central government, or as an honorary title conferred for service rendered to a superior political entity, or, finally, as a result of incorporation or legal enactment.
