In political science, a proxy war is an armed conflict where at least one of the belligerents is directed or supported by an external third-party power. In the term proxy war, a belligerent with external support is the proxy; both belligerents in a proxy war can be considered proxies if both are receiving foreign military aid from a third party country. Acting either as a nation-state government or as a conventional force, a proxy belligerent acts in behalf of a third-party state sponsor.
An insurgency is a violent, armed rebellion by small, lightly armed bands who practice guerrilla warfare against a larger authority. The key descriptive feature of insurgency is its asymmetric nature: small irregular forces face a large, well-equipped, regular military force state adversary. Due to this asymmetry, insurgents avoid large-scale direct battles, opting instead to blend in with the civilian population where they gradually expand territorial control and military forces. Insurgency frequently hinges on control of and collaboration with local populations.
Wars of national liberation, also called wars of independence or wars of liberation, are conflicts fought by nations to gain independence. The term is used in conjunction with wars against foreign powers to establish separate sovereign states for the rebelling nationality. From a different point of view, such wars are called insurgencies or rebellions. Guerrilla warfare or asymmetric warfare is often utilized by groups labeled as national liberation movements, often with support from other states. The term "wars of national liberation" is most commonly used for those fought during the decolonization movement. Since these were primarily in the third world, against Western powers and their economic influence, and a major aspect of the Cold War, the phrase has often been applied selectively to criticize the foreign power involved.
This timeline of United States military operations, based in part on reports by the Congressional Research Service, shows the years and places in which United States Armed Forces units participated in armed conflicts or occupation of foreign territories. Items in bold are wars most often considered to be major conflicts by historians and the general public.
War in Afghanistan, Afghan war, or Afghan civil war may refer to:
The United States government has been involved in numerous interventions in foreign countries throughout its history. The U.S. has engaged in nearly 400 military interventions between 1776 and 2023, with half of these operations occurring since 1950 and over 25% occurring in the post-Cold War period. Common objectives of U.S. foreign interventions have revolved around economic opportunity, social protection, protection of U.S. citizens and diplomats, territorial expansion, fomenting regime change, nation-building, and enforcing international law.
Irregular warfare (IW) is defined in United States joint doctrine as "a violent struggle among state and non-state actors for legitimacy and influence over the relevant populations" and in U.S. law as "Department of Defense activities not involving armed conflict that support predetermined United States policy and military objectives conducted by, with, and through regular forces, irregular forces, groups, and individuals." In practice, control of institutions and infrastructure is also important. Concepts associated with irregular warfare are older than the term itself.
The military history of the United Kingdom covers the period from the creation of the united Kingdom of Great Britain, with the political union of England and Scotland in 1707, to the present day.
The history of guerrilla warfare stretches back to ancient history. While guerrilla tactics can be viewed as a natural continuation of prehistoric warfare, the Chinese general and strategist Sun Tzu, in his The Art of War, was the earliest to propose the use of guerrilla warfare. This directly inspired the development of modern guerrilla warfare. Communist leaders like Mao Zedong and North Vietnamese Ho Chi Minh both implemented guerrilla warfare in the style of Sun Tzu, which served as a model for similar strategies elsewhere, such as the Cuban "foco" theory and the anti-Soviet Mujahadeen in Afghanistan. While the tactics of modern guerrilla warfare originate in the 20th century, irregular warfare, using elements later characteristic of modern guerrilla warfare, has existed throughout the battles of many ancient civilizations.
The decolonisation of Asia was the gradual growth of independence movements in Asia, leading ultimately to the retreat of foreign powers and the creation of several nation-states in the region.
The Arab Cold War was a political rivalry in the Arab world from the early 1950s to the late 1970s and a part of the wider Cold War. It is generally accepted that the beginning of the Arab Cold War is marked by the Egyptian Revolution of 1952, which led to Gamal Abdel Nasser becoming president of Egypt in 1956. Thereafter, newly formed Arab republics, inspired by revolutionary secular nationalism and Nasser's Egypt, engaged in political rivalries with conservative traditionalist Arab monarchies, influenced by Saudi Arabia. The Iranian Revolution of 1979, and the ascension of Ayatollah Ruhollah Khomeini as leader of Iran, is widely seen as the end of this period of internal conflicts and rivalry. A new era of Arab-Iranian tensions followed, overshadowing the bitterness of intra-Arab strife.
Political violence is violence which is perpetrated in order to achieve political goals. It can include violence which is used by a state against other states (war), violence which is used by a state against civilians and non-state actors, and violence which is used by violent non-state actors against states and civilians. It can also describe politically motivated violence which is used by violent non-state actors against a state or it can describe violence which is used against other non-state actors and/or civilians. Non-action on the part of a government can also be characterized as a form of political violence, such as refusing to alleviate famine or otherwise denying resources to politically identifiable groups within their territory.
A communist revolution is a proletarian revolution inspired by the ideas of Marxism that aims to replace capitalism with communism. Depending on the type of government, the term socialism can be used to indicate an intermediate stage between capitalism and communism and may be the goal of the revolution, especially in Marxist–Leninist views. The idea that a proletarian revolution is needed is a cornerstone of Marxism; Marxists believe that the workers of the world must unite and free themselves from capitalist oppression to create a world run by and for the working class. Thus, in the Marxist view, proletarian revolutions need to happen in countries all over the world.
A revolutionary wave is a series of revolutions occurring in various locations within a particular timespan. In many cases, past revolutions and revolutionary waves have inspired current ones, or an initial revolution has inspired other concurrent "affiliate revolutions" with similar aims. The causes of revolutionary waves have become the subjects of study by historians and political philosophers, including Robert Roswell Palmer, Crane Brinton, Hannah Arendt, Eric Hoffer, and Jacques Godechot.
