Nation in the context of "Pan-Arabism"

A country is an area of land, which has its own government and laws, or used to have them, such as a state, a nation, a nation state, or other political entity. When referring to a specific polity, the term "country" may refer to a sovereign state, a state with limited recognition, a constituent country, or a dependent territory. Most sovereign states, but not all countries, are members of the United Nations.

There is no universal agreement on the number of "countries" in the world with a range between 193 to 237. This ambiguity is a result of several states having disputed sovereignty status or limited recognition, and a number of non-sovereign entities are commonly considered countries. The definition and usage of the word "country" has fluctuated and changed over time. The Economist wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies."

Greeks or Hellenes (/ˈhɛliːnz/; Greek: Έλληνες, Éllines [ˈelines]) are an ethnic group and nation native to Greece, Cyprus, southern Albania, Anatolia, parts of Italy and Egypt, and to a lesser extent, other countries surrounding the Eastern Mediterranean and Black Sea. They also form a significant diaspora (omogenia), with many Greek communities established around the world.

Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people themselves have always been centered on the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age. Until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, Egypt, the Balkans, Cyprus, and Constantinople. Many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of ancient Greek colonization. The cultural centers of the Greeks have included Athens, Thessalonica, Alexandria, Smyrna, and Constantinople at various periods.

A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which share industries, commercial areas, transport network, infrastructure and housing. A metropolitan area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts and even states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.

In the United States, metropolitan areas are delineated around the core of a core based statistical area, which is defined as an urban area and includes central and outlying counties. In other countries metropolitan areas are sometimes anchored by one central city such as the Paris metropolitan area (Paris). In other cases, metropolitan areas contain multiple centers of equal or close to equal importance, especially in the United States; for example, the Dallas–Fort Worth metropolitan area has eight principal cities. The Islamabad–Rawalpindi metropolitan area in Pakistan, the Rhine-Ruhr in Germany, and the Randstad in The Netherlands are other examples.

World history or global history as a field of historical study examines history from a global perspective. It emerged centuries ago; some leading practitioners have included Voltaire (1694–1778), Hegel (1770–1831), Karl Marx (1818–1883), Oswald Spengler (1880–1936), and Arnold J. Toynbee (1889–1975). The field became much more active (in terms of university teaching, textbooks, scholarly journals, and academic associations) in the late 20th century.

It is not to be confused with comparative history, which, like world history, deals with the history of multiple cultures and nations, but does not do so on a global scale. World historians use a thematic approach, with two major focal points: integration (how processes of world history have drawn people of the world together) and difference (how patterns of world history reveal the diversity of the human experience).

The Western world, also known as the West, primarily refers to various nations and states in Western Europe, Northern America, and Australasia; with some debate as to whether those in Eastern Europe and Latin America also constitute the West. The Western world likewise is called the Occident (from Latin occidens 'setting down, sunset, west') in contrast to the Eastern world known as the Orient (from Latin oriens 'origin, sunrise, east'). Definitions of the "Western world" vary according to context and perspectives; the West is an evolving concept made up of cultural, political, and economic synergy among diverse groups of people, and not a rigid region with fixed borders and members.

Some historians contend that a linear development of the West can be traced from Ancient Greece and Rome, while others argue that such a projection constructs a false genealogy. A geographical concept of the West started to take shape in the 4th century CE when Constantine, the first Christian Roman emperor, divided the Roman Empire between the Greek East and Latin West. The East Roman Empire, later called the Byzantine Empire, continued for a millennium, while the West Roman Empire lasted for only about a century and a half. Significant theological and ecclesiastical differences led Western Europeans to consider the Christians in the Byzantine Empire as heretics. In 1054 CE, when the church in Rome excommunicated the patriarch of Byzantium, the politico-religious division between the Western church and Eastern church culminated in the Great Schism or the East–West Schism. Even though friendly relations continued between the two parts of Christendom for some time, the crusades made the schism definitive with hostility. The West during these crusades tried to capture trade routes to the East and failed, it instead discovered the Americas. In the aftermath of the European colonization of the Americas, primarily involving Western European powers, an idea of the "Western" world, as an inheritor of Latin Christendom emerged. According to the Oxford English Dictionary, the earliest reference to the term "Western world" was from 1586, found in the writings of William Warner.

A nation state, or nation-state, is a political entity in which the state (a centralized political organization ruling over a population within a territory) and the nation (a community based on a common identity) are broadly or ideally congruent. "Nation state" is a more precise concept than "country" or "state", since a country or a state does not need to have a predominant national or ethnic group.

A nation, sometimes used in the sense of a common ethnicity, may include a diaspora or refugees who live outside the nation-state; some dispersed nations (such as the Roma nation, for example) do not have a state where that ethnicity predominates. In a more general sense, a nation-state is simply a large, politically sovereign country or administrative territory. A nation-state may or may not be contrasted with:

An ethnicity or ethnic group is a group of people who identify with each other on the basis of perceived shared attributes that distinguish them from other groups. Attributes that ethnicities believe to share include language, culture, common sets of ancestry, traditions, society, religion, history, or social treatment. Ethnicities are maintained through long-term endogamy and may have a narrow or broad spectrum of genetic ancestry, with some groups having mixed genetic ancestry. Ethnicity is sometimes used interchangeably with nation, particularly in cases of ethnic nationalism. It is also used interchangeably with race although not all ethnicities identify as racial groups.

By way of assimilation, acculturation, amalgamation, language shift, intermarriage, adoption and religious conversion, individuals or groups may over time shift from one ethnic group to another. Ethnic groups may be divided into subgroups or tribes, which over time may become separate ethnic groups themselves due to endogamy or physical isolation from the parent group. Conversely, formerly separate ethnicities can merge to form a panethnicity and may eventually merge into one single ethnicity. Whether through division or amalgamation, the formation of a separate ethnic identity is referred to as ethnogenesis.

Macedonians (Macedonian: Македонци, romanized: Makedonci [maˈkɛdɔnt͡si]) are a nation and a South Slavic ethnic group native to the region of Macedonia in Southeast Europe. They speak Macedonian, a South Slavic language. The large majority of Macedonians identify as Eastern Orthodox Christians, who share a cultural and historical "Orthodox Byzantine–Slavic heritage" with their neighbours. About two-thirds of all ethnic Macedonians live in North Macedonia; there are also communities in a number of other countries.

The concept of a Macedonian ethnicity, distinct from their Orthodox Balkan neighbours, is seen to be a comparatively newly emergent one. The earliest manifestations of an incipient Macedonian identity emerged during the second half of the 19th century among limited circles of Slavic-speaking intellectuals, predominantly outside the region of Macedonia. They arose after the First World War and especially during the 1930s, and thus were consolidated by Communist Yugoslavia's governmental policy after the Second World War.The formation of the ethnic Macedonians as a separate community has been shaped by population displacement as well as by language shift, both the result of the political developments in the region of Macedonia during the 20th century. Following the dissolution of the Ottoman Empire, the decisive point in the ethnogenesis of the South Slavic ethnic group was the creation of the Socialist Republic of Macedonia after World War II, a state in the framework of the Socialist Federal Republic of Yugoslavia. This was followed by the development of a separate Macedonian language and national literature, and the foundation of a distinct Macedonian Orthodox Church and national historiography.
