Bipolar World

"Bipolar World" is a term used to describe a world political climate in which nations form factions built around one of two comparatively equal superpowers. Its opposite, in which one superpower stands above the others, is a Unipolar World.

The classic case of a bipolar world is that of the Cold War etween the United States of America and the Soviet Union, which dominated the second half of the twentieth century. But the phenomenon of a bipolar world is not new. In 1494, the [Treaty Of Tordesillas] effectively divided the New World between Portugal and Spain, and was sanctioned by the Vatican.
