What impact did USA have on world war one?

Answer 1

it got effected because.................

Simply put, World War One began in the year 1914 and ended in 1918.

The initial catalyst was in June 1914: the assassination of Austrian Archduke Franz Ferdinand in Sarajevo, Serbia. The Austro-Hungarian empire wanted to extradite the killer, but Serbia refused.

Once the spark of the Archduke's assassination had lit the fuse, war became virtually inevitable due to the alliance system that the major powers had set up - they literally tumbled into war.

Austria mobilized, Serbia mobilized, in response to Austrian mobilization against Serbia, Russia mobilized, in response to Russian mobilization against Austria, Germany mobilized and in response to German mobilization both Britain and France mobilized.

In the summer of 1914 the war began to rage in both the east and the west. It would not end until November 1918.

Here are some key dates:

28 July 1914: Austria declared war on Serbia.

1 August 1914: Germany declared war on Russsia.

3 August 1914: Germany declared war on France. WWI had begun.

4 August 1914: Britain declares was on Germany.

11 November 1918: It ended on the 11th hour of the 11th day of the 11th month.

France declares war on Germany on 3rd August as they had a treaty with Russia. Germany invades neutral Belgium as it's the shortest route to Paris.

Britain declares war on Germany on 4th August as they have a "Moral obligation" to defend France. Britain was also obliged to defend Belgium. This then drew British dominions into the war which included Australia, Canada, India and South Africa.

Japan declared war on Germany on 23rd August 1914 honouring agreement with Britain.

Italy joined on the Allies side in May 1915.

US tries to stay neutral but when Germany starts unrestricted submarine warfare which threatens US commercial shipping, the US enters the war on April 6th 1917.

March 1917 Russian revolution breaks out (in Petrograd/St Petersburg) which leads to the abdication of Tzar Nicholas II and in turn the formal withdrawl of Russia from the war when they sign the Treaty of Brest-Litovsk.

11/11/1918 Armistice Day-WW I ends (at 11 AM on Western Front).

More Input The First world war could be said to have started with the assassination of Archduke Franz Ferdinand of Austro-Hungary on 28th June 1914, although a war had looked imminent for several years. However Austria-Hungary didn't declare war on Serbia, the country where the supposed assassin came from, until a month later. Germany declared war on Russia, who supported the Serbs, on the 1st of August, and two days later declared war on Russia's ally, France. Germany then instigated the Schleiffen plan to invade France through Belgium, effectively declaring war on Belgium in the process. Britain, outraged at Germany's invasion of their ally Belgium declared war immediately, and the combined empires of Britain and France meant that much of the world was now at war.

However the British Expeditionary Force didn't arrive in France until the 22nd of August, and the first battles of the Great war weren't fought until late in August. The major battles (such as the first battle of the Marne and the first battle of Ypres) didn't start until the 6th of September and the 15th of October respectively. The United States didn't enter until the 6th of April 1917, and their troops didn't arrive in France until the 25th of June.

Unrest in Russia led as many as 2 million Russian soldiers to desert in the autumn of 1917. The new Bolshevik government signed a peace treaty, surrendering huge swathes of land, such as the Ukraine and Poland, to Germany on the 3rd of March 1918.

The allies finally broke through the line at Albert in Belgium on 21st August 1918, following this final "big push" with many other offensives on the German line, pushing the Germans into a retreat. The Allies captured the Hindenburg line, Germany's last line of defence on 5th October 1918. Kaiser Wilhelm abdicated the 9th of November 1918, and an armistace was arranged to take effect at the 11th hour of the 11th day of the 11th month 1918. This poetic date cost the lives of thousands of men, shots were fired in anger until the final seconds.

Comment "an armistice was arranged to take effect at the 11th hour of the 11th day of the 11th month 1918. This poetic date cost the lives of thousands of men, shots were fired in anger until the final seconds"

The armistice was scheduled to take effect as soon as practical. After all, it was essential to inform all units of the agreed time. Both sides feared that they would have difficulty doing this. The notion that the Allies in effect put poetry before lives is nonsense.

Answer 2

The United States Expeditionary Forces turned the tide for the allied powers in World War I. American troops were fresh and their morale high. European troops were seasoned troops, but were tired, unhappy, and running out.
