In the integrated and fortified medieval Cities of Europe surrounded by walls, into Boston and also the enormously growing, Las Vegas, or even London South East, the category of “cities” contain distinct density, boundaries, and measurements. For example the substance city of partitions, the ethnic city, the politics and policies of this city also, the market of the city. Urban regions have a powerful influence. Despite the rise and the fall, the different development observed during the different time periods, a majority of them possess a considerable amount of resources that have been gathered and in due course and can be used for a new phase of expansion. From the 19th and 20th century, the comparison between the ‘new America’ and ‘old Europe’ has been especially striking in urban issues. European societies are evidenced explicitly by the following characteristics: the institutionalization of social and financial existence, the significance of the nation and the welfare state, the territorialization of their market, science, and politics. Cities from the U.S.A. in comparison are component of this impressive success story of this Nation. Within the previous two centuries, as a part of an extremely mobile and not as a hierarchized society in which a highly efficient nation has traditionally played with a regulatory role compared to redistributive, in which privatism mostly surpasses the public domain.In this essay, I will discuss upon the formation of the initial urban scene in Europe and America. Characteristics of their new development, we will also be considering the dynamics of the economy in both the continents. Overall, the paper will compare the different situations encountered by these cities, and how they chose different models over the time, and how it has helped them in the transformation of their urban scenario.From the Western part of the world, cities started to shape up during the start of the first millennium, insinuating themselves to the openings of their feudal system. The medieval cities of Europe are viewed having the following attributes which include: a fortification, a sector and a particular urban market of consumption, production, and exchange; a court of law and also the capability to ordain an established of principles and legislation. The medieval town has been the crucible of Western societies, where new political and cultural versions improved, together with new social connections and cultural and political tendencies, furthered by interactions involving the diverse populations thus boosting mechanisms for studying a standard manner of existence. The Europe of towns wasn’t only the Europe of old capitalism and retailers, but also that the Europe of both intellectuals, universities, and civilization which started the Renaissance. The present urban map of Europe hugely reflects this Europe of cities that afterward grew increasingly, and therefore are even today in the forefront of urban expansion in Europe. The great era of European cities along with the comparative stability of the metropolitan system consequently represent a particular quality of European towns.
