76-510: In urban planning , a historic core city or central city is the municipality with the largest 1940 population in the present metropolitan area (metropolitan statistical area). This term was retired by the US census bureau and replaced by the term principal city , which can include historic core cities and post-WWII cities. Metropolitan areas were no longer considered monocentric, but polycentric due to suburbanization of employment. A historic core city
152-503: A royal house . A few of the smaller states survived, such as the independent principalities of Liechtenstein , Andorra , Monaco , and the republic of San Marino . Most theories see the nation state as a 19th-century European phenomenon, facilitated by developments such as state-mandated education, mass literacy , and mass media . However, historians also note the early emergence of a relatively unified state and identity in Portugal and
228-434: A federal state) is a political entity characterized by a union of partially self-governing provinces, states, or other regions under a central federal government ( federalism ). In a federation, the self-governing status of the component states, as well as the division of power between them and the central government, is typically constitutionally entrenched and may not be altered by a unilateral decision of either party,
304-465: A framework for urban planning decision-making. Another debate within the urban planning field is about who is included and excluded in the urban planning decision-making process. Most urban planning processes use a top-down approach which fails to include the residents of the places where urban planners and city officials are working. Sherry Arnstein 's "ladder of citizen participation" is often used by many urban planners and city governments to determine
380-941: A given area and thus, guides orderly development in urban, suburban and rural areas . Although predominantly concerned with the planning of settlements and communities, urban planners are also responsible for planning the efficient transportation of goods, resources, people, and waste; the distribution of basic necessities such as water and electricity; a sense of inclusion and opportunity for people of all kinds, culture and needs; economic growth or business development; improving health and conserving areas of natural environmental significance that actively contributes to reduction in CO 2 emissions as well as protecting heritage structures and built environments. Since most urban planning teams consist of highly educated individuals that work for city governments, recent debates focus on how to involve more community members in city planning processes. Urban planning
456-574: A limited way, empirically or normatively, and on whether conflict or co-operation is more essential to it. A variety of methods are deployed in politics, which include promoting one's own political views among people, negotiation with other political subjects, making laws , and exercising internal and external force , including warfare against adversaries. Politics is exercised on a wide range of social levels, from clans and tribes of traditional societies, through modern local governments , companies and institutions up to sovereign states , to
532-787: A political entity that has monopoly on violence within its territory, while the Montevideo Convention holds that states need to have a defined territory; a permanent population; a government; and a capacity to enter into international relations. A stateless society is a society that is not governed by a state . In stateless societies, there is little concentration of authority ; most positions of authority that do exist are very limited in power and are generally not permanently held positions; and social bodies that resolve disputes through predefined rules tend to be small. Stateless societies are highly variable in economic organization and cultural practices. While stateless societies were

Liberal ideas of free trade played a role in German unification, which was preceded by a customs union , the Zollverein . National self-determination was a key aspect of United States President Woodrow Wilson 's Fourteen Points , leading to
684-539: A result of some shared rational interest. The theories largely focus on the development of agriculture, and the population and organizational pressure that followed and resulted in state formation. One of the most prominent theories of early and primary state formation is the hydraulic hypothesis , which contends that the state was a result of the need to build and maintain large-scale irrigation projects. Conflict theories of state formation regard conflict and dominance of some population over another population as key to

836-463: A tool to improve the health and well-being of people, maintaining sustainability standards. Similarly, in the early 21st century, Jane Jacobs 's writings on legal and political perspectives to emphasize the interests of residents, businesses and communities effectively influenced urban planners to take into broader consideration of resident experiences and needs while planning. Urban planning answers questions about how people will live, work, and play in

Practitioners of urban planning are concerned with research and analysis, strategic thinking, engineering architecture, urban design , public consultation , policy recommendations, implementation and management. It is closely related to the field of urban design and some urban planners provide designs for streets, parks, buildings and other urban areas. Urban planners work with
1064-417: Is based on the use of power, irrespective of the ends being pursued. Agonism argues that politics essentially comes down to conflict between conflicting interests. Political scientist Elmer Schattschneider argued that "at the root of all politics is the universal language of conflict", while for Carl Schmitt the essence of politics is the distinction of 'friend' from 'foe'. This is in direct contrast to
1140-552: Is closely linked to ethics , and is at its extreme in utopian thinking. For example, according to Hannah Arendt , the view of Aristotle was that, "to be political…meant that everything was decided through words and persuasion and not through violence"; while according to Bernard Crick , "politics is the way in which free societies are governed. Politics is politics, and other forms of rule are something else." In contrast, for realists, represented by those such as Niccolò Machiavelli , Thomas Hobbes , and Harold Lasswell , politics
1216-598: Is continually being written by the legislative and judiciary branch of government; this is just one of those cases in which the nature of the circumstances determines the form of government that is most appropriate. England did set the fashion of written constitutions during the Civil War but after the Restoration abandoned them to be taken up later by the American Colonies after their emancipation and then France after
1292-437: Is embedded in a particular political culture. Lucian Pye 's definition is that, "Political culture is the set of attitudes, beliefs, and sentiments, which give order and meaning to a political process and which provide the underlying assumptions and rules that govern behavior in the political system." Trust is a major factor in political culture, as its level determines the capacity of the state to function. Postmaterialism
1368-459: Is evidence of urban planning and designed communities dating back to the Mesopotamian , Indus Valley , Minoan , and Egyptian civilizations in the third millennium BCE . Archaeologists studying the ruins of cities in these areas find paved streets that were laid out at right angles in a grid pattern. The idea of a planned out urban area evolved as different civilizations adopted it. Beginning in

Political science, as one of the social sciences , uses methods and techniques that relate to
1520-572: Is not limited to modern institutions of government . Frans de Waal argued that chimpanzees engage in politics through "social manipulation to secure and maintain influential positions". Early human forms of social organization—bands and tribes—lacked centralized political structures. These are sometimes referred to as stateless societies . In ancient history, civilizations did not have definite boundaries as states have today, and their borders could be more accurately described as frontiers . Early dynastic Sumer , and early dynastic Egypt were
1596-489: Is not to be confused with the core of a metropolitan area which is defined as an urban area with a population of over 50,000 by the US census bureau. Historic core cites in the United States often have higher detached single family housing rates, lower density, and fewer jobs than surrounding satellite cities and suburbs . A central city is usually the first settlement established in an urban region, years before

Politics may be used positively in the context of a "political solution" which is compromising and non-violent, or descriptively as "the art or science of government", but the word often also carries a negative connotation. The concept has been defined in various ways, and different approaches have fundamentally differing views on whether it should be used extensively or in
1748-634: Is the Geographic Information System (GIS) that is used to create a model of the existing planning and then to project future impacts on the society, economy and environment. Building codes and other regulations dovetail with urban planning by governing how cities are constructed and used from the individual level. Enforcement methodologies include governmental zoning , planning permissions , and building codes , as well as private easements and restrictive covenants . With recent advances in information and communication technologies and
1824-416: Is the body of scientific concepts, definitions, behavioral relationships, and assumptions that define the body of knowledge of urban planning. There are eight procedural theories of planning that remain the principal theories of planning procedure today: the rational-comprehensive approach, the incremental approach, the transactive approach, the communicative approach, the advocacy approach, the equity approach,

A pluralist strain of political thinking argues in a similar vein that the government should not intrude in the political competition between different interest groups which decides how land is used. The traditional justification for urban planning has in response been that the planner does to the city what
2128-710: The Dutch Republic . Scholars such as Steven Weber , David Woodward , Michel Foucault , and Jeremy Black have advanced the hypothesis that the nation state did not arise out of political ingenuity or an unknown undetermined source, nor was it an accident of history or political invention. Rather, the nation state is an inadvertent byproduct of 15th-century intellectual discoveries in political economy , capitalism , mercantilism , political geography , and geography combined with cartography and advances in map-making technologies . Some nation states, such as Germany and Italy , came into existence at least partly as
2204-544: The Enlightenment period , several European rulers ambitiously attempted to redesign capital cities. During the Second French Empire , Baron Georges-Eugène Haussmann , under the direction of Napoleon III , redesigned the city of Paris into a more modern capital, with long, straight, wide boulevards. Planning and architecture went through a paradigm shift at the turn of the 20th century. The industrialized cities of

These range from relatively egalitarian bands and tribes to complex and highly stratified chiefdoms . There are a number of different theories and hypotheses regarding early state formation that seek generalizations to explain why the state developed in some places but not others. Other scholars believe that generalizations are unhelpful and that each case of early state formation should be treated on its own. Voluntary theories contend that diverse groups of people came together to form states as

2812-549: The water supply , identifying transportation patterns, recognizing food supply demands, allocating healthcare and social services, and analyzing the impact of land use. In order to predict how cities will develop and estimate the effects of their interventions, planners use various models. These models can be used to indicate relationships and patterns in demographic, geographic, and economic data. They might deal with short-term issues such as how people move through cities, or long-term issues such as land use and growth. One such model
2888-917: The 18th century, the classic non-national states were the multinational empires : the Austrian Empire , Kingdom of France , Kingdom of Hungary , the Russian Empire , the Spanish Empire , the Ottoman Empire , and the British Empire .

The multinational empire
2964-511: The 19th century grew at a tremendous rate. The evils of urban life for the working poor were becoming increasingly evident as a matter of public concern. The laissez-faire style of government management of the economy, in fashion for most of the Victorian era , was starting to give way to a New Liberalism that championed intervention on the part of the poor and disadvantaged. Around 1900, theorists began developing urban planning models to mitigate
3040-571: The 4th century granted citizenship rights to their free population; in Athens these rights were combined with a directly democratic form of government that was to have a long afterlife in political thought and history. The Peace of Westphalia (1648) is considered by political scientists to be the beginning of the modern international system, in which external powers should avoid interfering in another country's domestic affairs. The principle of non-interference in other countries' domestic affairs
3116-454: The 8th century BCE, Greek city states primarily used orthogonal (or grid-like) plans. Hippodamus of Miletus (498–408 BC), the ancient Greek architect and urban planner, is considered to be "the father of European urban planning", and the namesake of the "Hippodamian plan" (grid plan) of city layout. The ancient Romans also used orthogonal plans for their cities. City planning in the Roman world

3268-702: The Multiple Nuclei Model among others. Participatory planning is an urban planning approach that involves the entire community in the planning process. Participatory planning in the United States emerged during the 1960s and 1970s. Technical aspects of urban planning involve the application of scientific, technical processes, considerations and features that are involved in planning for land use , urban design , natural resources , transportation , and infrastructure . Urban planning includes techniques such as: predicting population growth , zoning , geographic mapping and analysis, analyzing park space, surveying

The singular politic first attested in English in 1430, coming from Middle French politique —itself taking from politicus , a Latinization of the Greek πολιτικός ( politikos ) from πολίτης ( polites , 'citizen') and πόλις ( polis , 'city'). There are several ways in which approaching politics has been conceptualized. Adrian Leftwich has differentiated views of politics based on how extensive or limited their perception of what accounts as 'political' is. The extensive view sees politics as present across

Early urban planners were often members of these cognate fields though today, urban planning is a separate, independent professional discipline. The discipline of urban planning is the broader category that includes different sub-fields such as land-use planning , zoning , economic development , environmental planning , and transportation planning . Creating
3572-545: The coming of the Renaissance many new cities were enlarged with newly planned extensions. From the 15th century on, much more is recorded of urban design and the people that were involved. In this period, theoretical treatises on architecture and urban planning start to appear in which theoretical questions around planning the main lines, ensuring plans meet the needs of the given population and so forth are addressed and designs of towns and cities are described and depicted. During

Traditionally, urban planning followed
4180-427: The formation of states. In contrast with voluntary theories, these arguments believe that people do not voluntarily agree to create a state to maximize benefits, but that states form due to some form of oppression by one group over others. Some theories in turn argue that warfare was critical for state formation. The first states of sorts were those of early dynastic Sumer and early dynastic Egypt , which arose from
4256-448: The ideas of modernism in urban planning led to higher crime rates and social problems. In the second half of the 20th century, urban planners gradually shifted their focus to individualism and diversity in urban centers. Urban planners studying the effects of increasing congestion in urban areas began to address the externalities, the negative impacts caused by induced demand from larger highway systems in western countries such as in
4332-597: The interactions through which values are authoritatively allocated for a society." Each political system is embedded in a society with its own political culture, and they in turn shape their societies through public policy . The interactions between different political systems are the basis for global politics . Forms of government can be classified by several ways.

According to David Easton , "A political system can be designated as
4484-445: The more co-operative views of politics by Aristotle and Crick. However, a more mixed view between these extremes is provided by Irish political scientist Michael Laver, who noted that: Politics is about the characteristic blend of conflict and co-operation that can be found so often in human interactions. Pure conflict is war. Pure co-operation is true love. Politics is a mixture of both. The history of politics spans human history and

Another important aspect of urban planning is that the range of urban planning projects include the large-scale master planning of empty sites or Greenfield projects as well as small-scale interventions and refurbishments of existing structures, buildings and public spaces. Pierre Charles L'Enfant in Washington, D.C., Daniel Burnham in Chicago, Lúcio Costa in Brasília and Georges-Eugene Haussmann in Paris planned cities from scratch, and Robert Moses and Le Corbusier refurbished and transformed cities and neighborhoods to meet their ideas of urban planning.

An urban planner could be considered a green collar professional. Some researchers suggest that urban planners, globally, work in different " planning cultures ", adapted to their cities and cultures. However, professionals have identified skills, abilities, and basic knowledge sets that are common to urban planners across regional and national boundaries. The school of neoclassical economics argues that planning

In the 1920s, the ideas of modernism and uniformity began to surface in urban planning, and lasted until the 1970s. In 1933, Le Corbusier presented the Radiant City, a city that grows up in the form of towers, as a solution to the problem of pollution and over-crowding. But many planners started to believe that
