Hungary assumed a mandate to occupy and control Bosnia-Herzegovina, the Ottoman Empire kept its sovereignty, and Serbia was recognized as a kingdom; however, Serbians were incensed that Austria-Hungary had annexed Bosnia-Herzegovina during the Bosnian crisis of 1908 and 1909.

STRATEGIES TRENCH WARFARE In trench warfare both armies could fight from fortified positions. It was a slow form of combat with heavy reliance on defense. The soldiers built complex trench and dugout systems and stocked them with weapons. Barbed wire protected the trenches. The space between opposing armies’ trenches was “no man’s land. ” Attacks almost always resulted in injury and death for the attacking soldiers. CICERO © 2008

THE IMPORTANCE OF TRENCH WARFARE Trench warfare was an important part of combat during World War I. The effectiveness of the new weapons made it impossible to fight in the open for extended periods of time. Trenches were constructed for careful and planned attacks. The trench protected soldiers from attack. Soldiers also dug temporary trenches as close to the front lines as possible. These would protect waves of soldiers attacking the enemy. Attacking soldiers would take cover in a forward trench to regroup while other soldiers followed the first attack. Trenches kept soldiers out of the line of fire as much as possible.

OBJECTIVES ALLIED POWERS CENTRAL POWERS The main objective of the Allied Powers was to stop Germany and the Central Powers’ attempts to expand their land in Europe and Asia. The American conflict with Germany stemmed from Germany’s violation of a neutrality agreement when German submarines attacked American passenger ships. The main objective of the Central Powers was to acquire as much land as possible in Europe and Asia. Germany believed France, England, and Russia prevented its expansion. Germany was determined to expand its borders. CICERO © 2008

THE UNITED STATES ENTERS WORLD WAR I Originally, the United States pursued a policy of isolationism. After a German U-boat sank the British passenger ship Lusitania, President Woodrow Wilson demanded Germany end attacks on passenger ships. The British Royal Navy then intercepted the Zimmerman telegram in which a German diplomat encouraged Mexican officials to ally with German if the United States declared war on Germany. These events as well as the sinking of American merchant ships led the United States Congress to declare war on Germany on April 6, 1917. an American doughboy circa 1918 United States President Woodrow Wilson announces a break in diplomatic relations with Germany on February 3, 1917.

ARMISTICE ENDS THE WAR The armistice was reached on November 11, 1918. After a three days of negotiations, representatives of the Allied Powers and Germany signed the armistice on a railway carriage in Compiegne Forest on November 11, 1918. The expression “the eleventh of the eleventh” is derived from this date. The armistice went into effect at the eleventh hour, on the eleventh day, of the eleventh month. According to the armistice, German troops were to leave Belgium, France, and the eastern bank of the Rhine. The remainder of the German fleet was forced to surrender its weapons and ships to the Allied Powers. Germany also was forced to renounce its peace treaties with Russia and Romania. CICERO © 2008

THE TREATY OF VERSAILLES The Treaty of Versailles officially ended World War I. It was signed on June 28, 1919, at the Paris Peace Conference even though the armistice had been in place since November 11, 1918. Germany and its allies were required to accept full responsibility for World War I. Germany was required to disarm and concede any territorial gains made during the war. In addition, Germany was required to pay reparations to any countries it damaged during the war.

AFTERMATH OF WORLD WAR I In the aftermath of World War I, other conflicts that were a direct result of the war took place. Germans believed the Treaty of Versailles was unfairly punitive. Adolf Hitler gained popularity in Germany when he urged Germans to fight the injustices imposed on them after World War I. The collapse of the Ottoman Empire caused conflicts as nations sought to control territory in the Middle East. These conflict would intensify throughout the twentieth century and into the twenty-first century. future Chancellor of Germany, Adolf Hitler CICERO © 2008
