Wars leading to World War I
Three smaller wars led up to World War I. They were the Austro-Prussian War (1866), the Franco-Prussian War (1870-1871), and the Russo-Japanese War (1904-1905). The first two allowed Prussia to become the dominant German State, and eventually form the Second Reich (Empire). The Russo-Japanese War resulted in the world discovering the growing power of Japan in Asia and the weakness of Imperial Russia.
