RebellionRebellion, uprising, or insurrection is a refusal of obedience or order. It refers to the open resistance against the orders of an established authority. A rebellion originates from a sentiment of indignation and disapproval of a situation and then manifests itself by the refusal to submit or to obey the authority responsible for this situation. Rebellion can be individual or collective, peaceful (civil disobedience, civil resistance, and nonviolent resistance) or violent (terrorism, sabotage and guerrilla warfare).
Power vacuumIn political science and political history, the term power vacuum, also known as a power void, is an analogy between a physical vacuum to the political condition "when someone in a place of power, has lost control of something and no one has replaced them." The situation can occur when a government has no identifiable central power or authority. The physical analogy suggests that in a power vacuum, other forces will tend to "rush in" to fill the vacuum as soon as it is created, perhaps in the form of an armed militia or insurgents, military coup, warlord or dictator.
International securityInternational security is a term which refers to the measures taken by states and international organizations, such as the United Nations, European Union, and others, to ensure mutual survival and safety. These measures include military action and diplomatic agreements such as treaties and conventions. International and national security are invariably linked. International security is national security or state security in the global arena. By the end of World War II, a new subject of academic study, security studies, focusing on international security emerged.
Decolonization of the AmericasThe decolonization of the Americas occurred over several centuries as most of the countries in the Americas gained their independence from European rule. The American Revolution was the first in the Americas, and the British defeat in the American Revolutionary War (1775–1783) was a victory against a great power, aided by France and Spain, Britain's enemies. The French Revolution in Europe followed, and collectively these events had profound effects on the Spanish, Portuguese, and French colonies in the Americas.
