Buffer stateA buffer state is a country geographically lying between two rival or potentially hostile great powers. Its existence can sometimes be thought to prevent conflict between them. A buffer state is sometimes a mutually agreed upon area lying between two greater powers, which is demilitarized in the sense of not hosting the military of either power (though it will usually have its own military forces). The invasion of a buffer state by one of the powers surrounding it will often result in war between the powers.
Tributary stateA tributary state is a pre-modern state in a particular type of subordinate relationship to a more powerful state which involved the sending of a regular token of submission, or tribute, to the superior power (the suzerain). This token often took the form of a substantial transfer of wealth, such as the delivery of gold, produce, or slaves, so that tribute might best be seen as the payment of protection money.
Informal empireThe term informal empire describes the spheres of influence which a polity may develop that translate into a degree of influence over a region or country, which is not a formal colony, protectorate, tributary or vassal state of empire, as a result of its commercial, strategic or military interests. In a 2010 article, Gregory Barton and Brett Bennett defined informal empire as: A willing and successful attempt by commercial and political elites to control a foreign region, resource, or people.
FrançafriqueIn international relations, Françafrique (fʁɑ̃safʁik) is France's sphere of influence (or pré carré in French, meaning 'backyard') over former French and (also French-speaking) Belgian colonies in sub-Saharan Africa. The term was derived from the expression France-Afrique, which was used by the first president of Ivory Coast, Félix Houphouët-Boigny, in 1955 to describe his country's close ties with France.
Baltic WayThe Baltic Way (Baltijos kelias; Baltijas ceļš; Balti kett) or Baltic Chain (also "Chain of Freedom") was a peaceful political demonstration that occurred on 23 August 1989. Approximately two million people joined their hands to form a human chain spanning across the three Baltic states of Estonia, Latvia and Lithuania, which at the time were occupied and annexed by the USSR and had a combined population of approximately eight million. The central government in Moscow considered the three Baltic countries constituent republics of the Soviet Union.
Cultural areaIn anthropology and geography, a cultural area, cultural region, cultural sphere, or culture area refers to a geography with one relatively homogeneous human activity or complex of activities (culture). Such activities are often associated with an ethnolinguistic group and with the territory it inhabits. Specific cultures often do not limit their geographic coverage to the borders of a nation state, or to smaller subdivisions of a state.
