State (polity)

War is an armed conflict between the armed forces of states, or between governmental forces and armed groups that are organized under a certain command structure and have the capacity to sustain military operations, or between such organized groups.

It is generally characterized by widespread violence, destruction, and mortality, using regular or irregular military forces. Warfare refers to the common activities and characteristics of types of war, or of wars in general.

An enforced disappearance (or forced disappearance) is the secret abduction or imprisonment of a person with the support or acquiescence of a state followed by a refusal to acknowledge the person's fate or whereabouts with the intent of placing the victim outside the protection of the law. Often, forced disappearance implies murder whereby a victim is abducted, may be illegally detained, and is often tortured during interrogation, ultimately killed, and the body disposed of secretly. The party committing the murder has plausible deniability as there is no evidence of the victim's death.

Enforced disappearance was first recognized as a human rights issue in the 1970s as a result of its use by military dictatorships in Latin America during the Dirty War. However, it has occurred all over the world.

An archipelagic state is a state that rules an island country, consisting of one or more archipelagos. The designation is legally defined by the United Nations Convention on the Law of the Sea of 1982 (UNCLOS III). The Bahamas, Fiji, Indonesia, Papua New Guinea, and the Philippines are the five original sovereign states that obtained approval in the UNCLOS signed in Montego Bay, Jamaica, on 10 December 1982 and qualified as archipelagic states.

An archipelagic state can designate the waters between the islands as sovereign archipelagic waters.

An autonomous administrative division (also referred to as an autonomous area, zone, entity, unit, region, subdivision, province, or territory) is a subnational administrative division or internal territory of a sovereign state that has a degree of autonomy — self-governance — under the national government. Autonomous areas are distinct from other constituent units of a federation (e.g. a state, or province) in that they possess unique powers for their given circumstances. Typically, it is either geographically distinct from the rest of the state or populated by a national minority, which may exercise home rule. Decentralization of self-governing powers and functions to such divisions is a way for a national government to try to increase democratic participation or administrative efficiency or to defuse internal conflicts. States that include autonomous areas may be federacies, federations, or confederations. Autonomous areas can be divided into territorial autonomies, subregional territorial autonomies, and local autonomies.

A civilization (also spelled civilisation in British English) is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems).

Civilizations are organized around densely populated settlements, divided into more or less rigid hierarchical social classes of division of labour, often with a ruling elite and subordinate urban and rural populations, which engage in intensive agriculture, mining, small-scale manufacture and trade. Civilization concentrates power, extending human control over the rest of nature, including over other human beings. Civilizations are characterized by elaborate agriculture, architecture, infrastructure, technological advancement, currency, taxation, regulation, and specialization of labour.

Humans, scientifically known as Homo sapiens, are primates that belong to the biological family of great apes and are characterized by hairlessness, bipedality, and high intelligence. Humans have large brains compared to body size, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations.

Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups – from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's development of science, technology, philosophy, mythology, religion, and other frameworks of knowledge; humans also study themselves through such domains as anthropology, social science, history, psychology, and medicine. As of 2025, there are estimated to be more than 8 billion living humans.

There were many kingdoms and empires in all regions of the continent of Africa throughout history. A kingdom is a state with a king or queen as its head. An empire is a political unit made up of several territories, military outposts, and peoples, "usually created by conquest, and divided between a dominant centre and subordinate peripheries".

In Africa states emerged in a process covering many generations and centuries. Most states were created through conquest or the borrowing and assimilation of ideas and institutions, while some developed through internal, largely isolated development. Economic development "gave rise to a perceived need for centralized institutions and 'territorial' leadership that transcended older bonds of kinship and community". The politicoreligious struggle between the people and the king sometimes saw the people victorious and the establishment of sacred kings with little political power (termed "adverse sacralisation"), contrasted with divine kings equated to gods. Kings and queens used both "instrumental power", the employment of direct influence to achieve a desired outcome, and "creative power", the use of ritual and mythology.

A military operation (op) is the coordinated military actions of a state, or a non-state actor, in response to a developing situation. These actions are designed as a military plan to resolve the situation in the state or actor's favor. Operations may be of a combat or non-combat nature and may be referred to by a code name for the purpose of national security. Military operations are often known for their more generally accepted common usage names than their actual operational objectives. The operational level of war is between tactics and strategy.

Private law is the part of a legal system that governs interactions between individual persons. It is distinguished from public law, which deals with relationships between both natural and artificial persons (i.e., organizations) and the state, including regulatory statutes, penal law and other law that affects the public order. In general terms, private law involves interactions between private individuals, whereas public law involves interrelations between the state and the general population. In legal systems of the civil law tradition, it is that part of the jus commune that involves relationships between individuals, such as the law of contracts and torts (as it is called in the common law tradition), and the law of obligations (as it is called in the civil law tradition).

A prison, also known as a jail, gaol, penitentiary, detention center, correction center, correctional facility, or remand center, is a facility where people are imprisoned under the authority of the state, usually as punishment for various crimes. They may also be used to house those awaiting trial (pre-trial detention). Prisons serve two primary functions within the criminal-justice system: holding people charged with crimes while they await trial, and confining those who have pleaded guilty or been convicted to serve out their sentences.

Prisons can also be used as a tool for political repression by authoritarian regimes who detain perceived opponents for political crimes, often without a fair trial or due process; this use is illegal under most forms of international law governing fair administration of justice. In times of war, belligerents or neutral countries may detain prisoners of war or detainees in military prisons or in prisoner-of-war camps. At any time, states may imprison civilians – sometimes large groups of civilians – in internment camps.
