World War I was fought between two major alliances of countries: the Allied Powers and the Central Powers. The Central Powers began as an alliance between Germany and Austria-Hungary. Later the Ottoman Empire and Bulgaria became part of the Central Powers.
Germany - Germany had the largest army and was the primary leader of the Central Powers. Germany's military strategy at the start of the war was called the Schlieffen Plan. This plan called for the quick takeover of France and Western Europe. Then Germany could concentrate its efforts on Eastern Europe and Russia.
Austria-Hungary - World War I essentially began when Archduke Ferdinand was assassinated. Austria-Hungary blamed the assassination on Serbia and subsequently invaded Serbia setting off a chain of events that resulted in the war.
Ottoman Empire - The Ottoman Empire had strong economic ties to Germany and signed a military alliance with Germany in 1914. The entrance into the war led to the eventual downfall of the Ottoman Empire and the formation of the country of Turkey in 1923.
Bulgaria - Bulgaria was the last major country to join the war on the side of the Central Powers in 1915. Bulgaria claimed land held by Serbia and was eager to invade Serbia as part of the war.
