Why did the Anglo-Japanese Alliance end?

Question:

Spheres of Influence

The term ''sphere of influence'' is used in foreign relations to indicate that a particular nation has declared exclusive political and/or economic interests in a region within another country or an entire country or even a certain region of the world. It is important to note that just because a nation claims that an area is within its sphere of influence, that claim may or may not be acknowledged by other nations.

Powerful countries, over the past several millennia, have often sought to exert their authority on other nations – either through total subjugation, diplomatic agreements, or other avenues. But the first time that the term ''sphere of influence'' was officially used was in connection with an agreement between Great Britain and Germany in 1885, in which Germany claimed territory and authority in the eastern part of lands in Africa's Gulf of Guinea, and Britain claimed similar influence in the western part.

Other examples of governments negotiating, developing, or demanding what amounted to establishing spheres of influence are the United States' Monroe Doctrine (1823) whereby it claimed exclusive rights to the acquiring of territory in the ''New World''; the economic and political carving up of China in the late nineteenth and early twentieth centuries by Germany, Russia, France, Britain, and Japan; and, after World War II, the Soviet Union establishing its influence over nations in Central and Eastern Europe and other countries.
