to raise military manpower after only 73,000 volunteers enlisted out of the initial 1million target in the first six weeks of the war. In 1917 10 million men were registered. This was deemed to be inadequate, so age ranges were increased and exemptions reduced, and so by the end of 1918 this increased to 24 million men that were registered with nearly 3million inducted into the military services. The draft was universal and included blacks on the same terms as whites, although they served in different units. In all 367,710 black Americans were drafted (13% of total), compared to 2,442,586 white (87% of total). Forms of resistance ranged from peaceful protest to violent demonstrations and from humble letter-writing campaigns asking for mercy to radical newspapers demanding reform. The most common tactics were dodging and desertion, and many communities sheltered and defended their draft dodgers as political heroes. Many socialists were jailed for "obstructing the recruitment or enlistment service". The most famous was Eugene Debs, head of the Socialist Party of America, who ran for president in 1920 from his prison cell. In 1917 a number of radicals and anarchists challenged the new draft law in federal court, arguing that it was a direct violation of the Thirteenth Amendment's prohibition against slavery and involuntary servitude. The Supreme Court unanimously upheld the constitutionality of the draft act in the Selective Draft Law Cases on 7January 1918. Austria-Hungary Like all the armies of mainland Europe, Austria-Hungary relied on conscription to fill its ranks. Officer recruitment, however, was voluntary. The effect of this at the start of the war was that well over a quarter of the rank and file were Slavs, while more than 75% of the officers were ethnic Germans. This was much resented. The army has been described as being "run on colonial lines" and the Slav soldiers as "disaffected". Thus conscription contributed greatly to Austria's disastrous performance on the battlefield. Diplomacy The non-military diplomatic and propaganda interactions among the nations were designed to build support for the cause or to undermine support for the enemy. For the most part, wartime diplomacy focused on five issues: propaganda campaigns; defining and redefining the war goals, which became harsher as the war went on; luring neutral nations (Italy, Ottoman Empire, Bulgaria, Romania) into the coalition by offering slices of enemy territory; and encouragement by the Allies of nationalistic minority movements inside the Central
