On July 28th 1914...
This marked the spark of the great war that lead the most powerful nations to fight until one surrenders. Germany, Italy, and Prussia worked together witch they called it the Triple Alliance. Germany's goal was to conquer Russia, and France. Germany was strong and had a army with weapons to take down both nations for property and resources. German industrial and economic power had grown greatly after unification and the foundation of the Empire in 1871 following the Franco-Prussian War.
Germany's plain of attack was to invade France since they had the number of men on there side and weapons while Austria-Hungary was to invade Russia but they divided there man. At the time Russia didn't have the amount of weapons to fight back it was one gun for every ten man. Austria invaded and fought the Serbian army at the Battle of Cer, and Battle of Kolubara beginning on 12 August. Austrian attacks were thrown back with heavy losses which marked the first major Allied victories of the war and dashed Austro-Hungarian hopes of a swift victory.
When Germany invade France they broke through there first walls and tried defending the position This meant Germany failed to achieve its objective of avoiding a long two front war. But before Germany lost they were able to use what ever supplies they had from taking over the first objective witch was the coal, they were able to kill over 230,000 France, and British troops witch lead to the re control of France base but with a heavy price of troops and supplies.
A formal state of war between the two sides persisted for another seven months, until the signing of the Treaty of Versailles with Germany on 28 June 1919. The United States Senate did not ratify the treaty despite public support for it and did not formally end its involvement in the war until the Knox Porter Resolution was signed on 2 July 1921 by President Warren G. Harding after the Treaty of Versailles, treaties with Austria, Hungary, Bulgaria, and the Ottoman Empire were signed. However, the negotiation of the latter treaty with the Ottoman Empire was followed by strife, and a final peace treaty between the Allied Powers and the country that would shortly become the Republic of Turkey was not signed until 24 July 1923, at Lausanne. Some war memorials date the end of the war as being when the Versailles Treaty was signed in 1919, which was when many of the troops serving abroad finally returned to their home countries; by contrast, most commemorations of the war's end concentrate on the armistice of 11 November 1918.
