The English word politics has its roots in the name of Aristotle's classic work, Politiká, which introduced the Ancient Greek term politiká (Πολιτικά, 'affairs of the cities'). In the mid-15th century, Aristotle's composition was rendered in Early Modern English as Polettiques [sic], which became Politics in Modern English.

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').
• Harold Lasswell: "who gets what, when, how"
• David Easton: "the authoritative allocation of values for a society"
• Vladimir Lenin: "the most concentrated expression of economics"
• Otto von Bismarck: "the capacity of always choosing at each instant, in constantly changing situations, the least harmful, the most useful"
• Bernard Crick: "a distinctive form of rule whereby people act together through institutionalized procedures to resolve differences"
• Adrian Leftwich: "comprises all the activities of co-operation, negotiation and conflict within and between societies"

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 the sphere of human social relations, while the limited view restricts it to certain contexts. For example, in a more restrictive way, politics may be viewed as primarily about governance, while a feminist perspective could argue that sites which have been viewed traditionally as non-political, should indeed be viewed as political as well. This latter position is encapsulated in the slogan "the personal is political", which disputes the distinction between private and public issues. Politics may also be defined by the use of power, as has been argued by Robert A. Dahl.
Some perspectives on politics view it empirically as an exercise of power, while others see it as a social function with a normative basis. This distinction has been called the difference between political moralism and political realism. For moralists, politics 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 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 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 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 the first civilizations to define their borders. Moreover, up to the 12th century, many people lived in non-state societies. 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 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 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 the Uruk period and Predynastic Egypt respectively around approximately 3000 BC. Early dynastic Egypt was based around the Nile River in the north-east of Africa, the kingdom's boundaries being based around the Nile and stretching to areas where oases existed. Early dynastic Sumer was located in southern Mesopotamia, with its borders extending from the Persian Gulf to parts of the Euphrates and Tigris rivers.

Egyptians, Romans, and the Greeks were the first people known to have explicitly formulated a political philosophy of th…
