Benito Mussolini seized power in Italy in the 1920s and established a fascist government, creating the "black shirts" militia to enforce his rule. He invaded Ethiopia in Africa and Japan attacked Manchuria in China, and both faced ineffective responses from the League of Nations. In Germany, Adolf Hitler rose to power as the Nazi party leader and chancellor, preaching against the unfair Treaty of Versailles and beginning to remilitarize the country by sending troops to the Rhineland. The authoritarian leaders of Italy, Germany and Japan would later form the Axis alliance.
