World War I 1914 - 1918

In 1914 in Sarajevo when Gavrilo Princip, a member of the Black Hand, assassinated the Archduke of Austria, Franz Ferdinand there was an outrage in Austria-Hungary to retaliate. Blaming Serbia for the death of Franz Ferdinand and his wife, Austria-Hungary got the blank check from Germany and declared war on Serbia on July 28, 1914.
After Austria-Hungary declares war on Serbia on July 28th, 1914, Russia begins to mobilize their troops two days later due to their alliance with Serbia. In response, Germany declares war on Russia and her allies this far, being France and Serbia. By August 4th, 1914, the countries at war were Russia, France, Britain, and Serbia versus Germany and Austria-Hungary.
On August 3rd, 1914, Germany invades a neutral Belgium and begins to wreak havoc because of the small amount of resistance they face from the Belgian civilians. They burn houses and murder helpless citizens. They also invade Poland, a Russian territory, on August 4th and take three of the towns. Then, in solidarity with Britain and a few anterior motives, Japan declares war on Germany on August 23rd, 1914.

On April 22nd, 1915, Germany starts using coloring shells and fires them at Allied lines. In France, it was almost enough to break the line, but the Germans could not advance due to the gas that still lingered in the air.

Submarines in World War I were a crucial aspect of why the United States of America joined the war. After the Lusitania, a passenger liner, carrying around 1,200 people with around 200 Americans was sank by a German U-Boat on May 7th, 1915 the United States was outraged. On September 18th, 1915 Kaiser Wilhelm suspended the aggressive submarine warfare in an attempt to keep America out of the war. However, this severely hampered their attempts to keep the support and aid from the U.S. to Britain and France. Another technological advancement of World War I was the introduction of tanks. Thinking they would turn the tide of the war, the British introduced the first tank, the British Mark 1, on September 15th, 1916. With mixed results, tanks would not heavily affect the war until near the end because of the unreliability of the tanks.

After the Germans reintroduce submarine warfare on February 1st, 1917, and the Zimmerman Telegraph in which Germany contacted Mexico and told them that they would help them get Texas and other land back in exchange for their alliance in the Great War (even though Mexico declined) led to the entrance of the United States into World War I on April 6th, 1917.

In November 17th, 1917 Russia left the war because of internal conflicts and fighting, which allowed roughly 900,000 German troops to be reallocated to the other fronts in World War I. The United States had not officially sent over any troops to fight at this point and the Allied Forces were worried about the influx of German troops to their front lines.
After Germany and Russia came to an agreement and Russia had left the war, Germany started the Spring (Ludendorff) Offensive in March of 1918. Throughout this set of wars, both sides lost a large chunk of soldiers. By the time this offensive was over both the Germans and the Allied forces were exhausted. Germans had taken control of a little tract of land, but the war was not over yet.
After the German's last two spring offensives fail to put them in control of the war, the Allies go on a counterattack starting on August 8th, 1918. This was known as the Allied Hundred Days Offensive and was a crucial part of the end of the First World War. On October 4th, 1918 Germany asked the Allies for an armistice, and on the 11th day of the 11th month at the 11th hour Germany signs an armistice with the Allies. On November 11th, 1918, World War I was over.
