Not very reliable and used mostly at the end of the war 5) Aircraft – used mostly for observing enemy locations at the beginning of the war, by the end airplanes were used to drop bombs from the air. Despite the new technologies, neither side was able to break the stalemate created by the trenches.

War Around the World While much of the fighting of WWI took place in western Europe, over 30 nations took part in the war and fighting spread all over the world The Gallipoli Campaign – battles between the Allies and the Ottoman Empire over an area called the Dardanelles. The Allies were unsuccessful in taking the Dardanelles and was a failure for the Allies.

24. War Around the World The Armenian Massacre – in late 1914 the Russians attacked the Ottoman Empire in the Caucasus mountains.

Other battles took place in Asia and Africa, and soldiers from around the world fought in WWI.

27. The U.S. Enters the War America declared neutrality – declaring no side However, America supported the Allies by providing aid and money. This angered Germany and they used U-boats to sink the British ship Lusitania, killing more than 1000 people, including 128 Americans. Germany then announced that it would sink all ships in British waters, regardless of where they were from

28. The U.S. Enters the War Americans were already upset over the sinking of British ships In 1917 British agents intercepted the Zimmerman Note – a telegram that proposed an alliance between Germany and Mexico against the United States. On April 6, 1917 Congress declared war on Germany.

29. The War Comes to an End Germany knew that the addition of the United States would greatly strengthen the Allies so they decided to attempt one final blow before the U.S. had time to get to the front lines. Without the Russians involved Germany focused all its efforts on the western front.

Treaty of Versailles Effects of the treaty –1) Germans were furious over the humiliating terms but they had no choice other than signing –2) The creation of a League of Nations However, Germany was left out of the League and the United States rejected the Treaty of Versailles because Americans feared that joining the League would eventually drag them into more European wars.
