A satellite state or dependent state is a country that is formally independent but under heavy political, economic, and military influence or control from another country. The term was coined by analogy to planetary objects orbiting a larger object, such as smaller moons revolving around larger planets, and is used mainly to refer to Central and Eastern European member states of the Warsaw Pact during the Cold War, as well as to Mongolia and Tuva between 1924 and 1990, all of which were economically, culturally, and politically dominated by the Soviet Union. While primarily referring to the Soviet-controlled states in Central and Eastern Europe or Asia, in some contexts the term also refers to other countries under Soviet hegemony during the Cold War, such as North Korea, Cuba, and some countries in the American sphere of influence, such as South Vietnam. In Western usage, the term has seldom been applied to states other than those in the Soviet orbit. In Soviet usage, the term applied to states in the orbit of Nazi Germany, Fascist Italy, and Imperial Japan, whereas in the West the term to refer to those has typically been client states.
Superpower describes a sovereign state or supranational union that holds a dominant position characterized by the ability to exert influence and project power on a global scale. This is done through the combined means of economic, military, technological, political, and cultural strength as well as diplomatic and soft power influence. Traditionally, superpowers are preeminent among the great powers. While a great power state is capable of exerting its influence globally, superpowers are states so influential that no significant action can be taken by the global community without first considering the positions of the superpowers on the issue.
A puppet state, puppet régime, puppet government or dummy government is a state that is de jure independent but de facto completely dependent upon an outside power and subject to its orders. Puppet states have nominal sovereignty, except that a foreign power effectively exercises control through economic or military support. By leaving a local government in existence the outside power evades all responsibility, while at the same time successfully paralysing the local government they tolerate.
In the field of international relations, a client state, is a state that is economically, politically, and militarily subordinated to a more powerful controlling state. Alternative terms for a client state are satellite state, associated state, and dominion, condominium, self-governing colony, and neo-colony, protectorate, vassal state, puppet state, and tributary state.
A demilitarized zone is an area in which treaties or agreements between states, military powers or contending groups forbid military installations, activities, or personnel. A DZ often lies along an established frontier or boundary between two or more military powers or alliances. A DZ may sometimes form a de facto international border, such as the Korean Demilitarized Zone. Other examples of demilitarized zones are a 14 km (8.7 mi) wide area between Iraq and Kuwait; Antarctica ; and outer space.
The term "Soviet empire" collectively refers to the world's territories that the Soviet Union dominated politically, economically, and militarily. This phenomenon, particularly in the context of the Cold War, is also called Soviet imperialism by Sovietologists to describe the extent of the Soviet Union's hegemony over the Second World.
In the field of international relations, a sphere of influence (SOI) is a spatial region or concept division over which a state or organization has a level of cultural, economic, military, or political exclusivity.
Decolonization is the undoing of colonialism, the latter being the process whereby imperial nations establish and dominate foreign territories, often overseas. The meanings and applications of the term are disputed. Some scholars of decolonization focus especially on independence movements in the colonies and the collapse of global colonial empires.
The Cold War was a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc, that started in 1947, two years after the end of World War II, and lasted until the fall of the Soviet Union in 1991.
The causes of World War II have been given considerable attention by historians. The immediate precipitating event was the invasion of Poland by Nazi Germany on September 1, 1939, and the subsequent declarations of war on Germany made by Britain and France, but many other prior events have been suggested as ultimate causes. Primary themes in historical analysis of the war's origins include the political takeover of Germany in 1933 by Adolf Hitler and the Nazi Party; Japanese militarism against China, which led to the Japanese invasion of Manchuria and the Second Sino-Japanese War; Italian aggression against Ethiopia, which led to the Second Italo-Ethiopian War; Soviet Union desire to reconquer old territory of Russian Empire, which led to the Soviet invasion of Poland, the Soviet occupation of Bessarabia and Northern Bukovina, the occupation of the Baltic states and the Winter War.
Almost every country in the world participated in World War II. Most were neutral at the beginning, but only a relative few nations remained neutral to the end. The Second World War pitted two alliances against each other, the Axis powers and the Allied powers. It is estimated that 74 million people died, with estimates ranging from 40 million to 90 million dead. The main Axis powers were Nazi Germany, the Empire of Japan, and the Kingdom of Italy; while the United Kingdom, the United States, the Soviet Union and China were the "Big Four" Allied powers.
This is a timeline of the main events of the Cold War, a state of political and military tension after World War II between powers in the Western Bloc and powers in the Eastern Bloc.
An international zone is any area not fully subject to the border control policies of the state in which it is located. There are several types of international zones ranging from special economic zones and sterile zones at ports of entry exempt from customs rules to concessions over which administration is ceded to one or more foreign states. International zones may also maintain distinct visa policies from the rest of the surrounding state.
The aftermath of World War II saw the rise of two superpowers, the Soviet Union (USSR) and the United States (US). The aftermath of World War II was also defined by the rising threat of nuclear warfare, the creation and implementation of the United Nations as an intergovernmental organization, and the decolonization of Asia, Oceania, South America and Africa by European and East Asian powers, most notably by the United Kingdom, France, and Japan.
Relations between the Japanese Empire and the Russian Empire (1855–1917) were minimal until 1855, mostly friendly from 1855 to the early 1890s, but then turned hostile, largely over the status of Manchuria and of Korea. The two empires established diplomatic and commercial relations from 1855 onwards. The Russian Empire officially ended in 1917, and was succeeded by Communist rule formalized in 1922 with the formation of the Soviet Union.
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 territorial conquests of the Japanese Empire in the Western Pacific Ocean and East Asia began in 1895 with its victory over Qing China in the First Sino-Japanese War. Subsequent victories over the Russian Empire and the German Empire expanded Japanese rule to Taiwan, Korea, Micronesia, southern Sakhalin, several concessions in China, and the South Manchuria Railway. In 1931, Japan invaded Manchuria, resulting in the establishment of the puppet state of Manchukuo the following year; thereafter, Japan adopted a policy of founding and supporting puppet states in conquered regions. These conquered territories became the basis for the Greater East Asia Co-Prosperity Sphere in 1940.
