From Ancient Times to World War II

Historical examples of power balancing are found throughout history in various regions of the world, leading some scholars to characterize balance of power as a universal and timeless principle. During the Period of the Warring States in China (403-221 bc), the development of large, cohesive states accompanied the creation of irrigation systems, bureaucracies, and large armies equipped with iron weapons. These Chinese states pursued power through a constantly shifting network of alliances. In ancient Greece during the Peloponnesian War (431-404 bc), the rising power of Athens triggered the formation of a coalition of city-states that felt threatened by Athenian power. The alliance, led by Sparta, succeeded in defeating Athens and restoring a balance of power among Greek cities.

In the 17th century the Habsburg dynasty, which ruled Austria and Spain, threatened to dominate Europe. During the Thirty Years’ War (1618-1648), a coalition that included Sweden, England, France, and The Netherlands defeated the rulers of the Habsburg Empire. Early in the 19th century, French emperor Napoleon I repeatedly made efforts to conquer large areas of Europe. A broad coalition of European states—including Britain, Russia, Austria, and Prussia—defeated France in a series of major battles that climaxed with Napoleon’s defeat at the Battle of Waterloo in 1815.

The classical European balance of power system emerged thereafter in an alliance known as the Concert of Europe, organized in 1815 by Austrian statesman Klemens von Metternich. This loose alliance between Britain, Russia, Austria, Prussia, and France ensured that a handful of great powers would coexist, with none able to dominate the others. Under this system, and with Britain playing a balancer role, peace largely prevailed in Europe during the 19th century. During World War II, Germany’s rising power, aggressive conquests, and alliance with Italy and Japan triggered yet another coalition of opposing states—notably the capitalist democracies of Britain and the United States, and the Communist Soviet Union.
