The leaders of these European nations believed this system of alliances created a “balance of power” that would prevent war. They were wrong. Tensions actually increased as nationalistic rivalries and the competition for colonies continued. Even the alliances themselves underwent change. Italy, which sought territory controlled by Austria-Hungary, dropped out of the Triple Alliance and later joined the nations that made up the Triple Entente.
When war broke out in 1914, Bulgaria and the Ottoman Empire joined Germany and Austria-Hungary to form what was known as the Central Powers. France, Russia, and Great Britain were joined by Serbia and other nations to form the Allied Powers. The United States became part of the Allied Powers when it entered the war in 1917.
