Why did US declare war on Germany ww1?

Answer 1

Well it started with the sinking of the Lusitannia by a German submarine. The US pushed the German government into signing a treaty that made sinking non-warships illegal, and they must let the crew exit the ship before sinking it. The Germans agreed at first, then when they started loosing the war they restarted sinking US cargoships so that Britain and France would not get resources from the US.
Germany's unrestricted U-Boat policy which was killing US Citizens.
America didn't want to enter any war. The only reason that America entered WW1 was because a German proto-type sub sunk one of their cruise ships.
The German U-Boat attacks on US shipping in the Atlantic.

There was also the Zimmermann note, a telegram from the German foreign ministerto the German ambassador in Mexico that was intercepted by British agents. The telegramproposed an alliance between Mexico and Germany and promised that if war with the united states broke out, Germany would support Mexico in recovering lost territory in Texas, New Mexico, an Arizona.
The first primary cause leading to the entry of the United States into World War I was the loss of American lives and goods through the sinking of American ships by German submarines. The second primary cause, fueled by the first, was a sharp increase in resentment towards Germany for alleged and actual intrigue (such as a possible alliance with Mexico) and atrocities (such as their brutal treatment of Belgians in Europe).
A German U-boat sank a british liner Lusitania in 1915, with 128 Americans on board and the sinking of 7 U.S merchant ships by German submarines and the Zimmerman Telegram. U.S Congress declared war on Germany in April 6, 1917
What caused the Us to enter the war?

The Us entered WW1 because of the sinking of the Lusitania after the Germans torpedoed it. Another reason for entering the war was because of the Bolshevik Revolution. The Bolsheviks over threw the Russian Czar and took control of Russia. The Treaty of Brest-Litovsk ended Russia's participation in the war and gave large amounts of land to Germany.
The USA joined the war in April, 1917 mainly because of the German gamble of sinking supply ships heading to Britain.
These supply ships were mainly American and because of this, America eventually declared war.
Other things such as a general dislike of Germans at that time, Propaganda as well as already supporting Britain through trade brought about America entering the war
1. The USA wanted revenge for the sinking of the Lusitania, a transport ship travelling from New York to Britain. The Germans surrounded the Lusitania with their U-boat submarines and sunk it, killing every person on board.

2. The UK and France both owed America money, roughly two million dollars in total and if Britain and France were to lose, they would not be able to pay America back.

3. Propaganda from the UK also influenced America to join the war. By joining it got to show it's power and domination over the world.

4. The Zimmerman Note is what finally pushed America to join the war. The Note was a Telegram that was sent from the German Foreign Secretary to the German Ambassador to Mexico. It stated:

• On the first of February, 1917, submarine warfare will be reinstated unrestrictively.

• The US has to stay neutral.

• Germany proposes an alliance with Mexico on the following basis: If the US goes to war, Mexico must fight on the home front in a financially supported alliance with Germany; If Mexico agrees to fight, they will reconquer New Mexico, Texas and Arizona.

The telegraph was intercepted by British Intelligence and transmitted to the American press by the Brits. This infuriated American citizens and so the Government had no choice but to join the war.

5. The Russian revolution was another reason but I don't know enough about it myself to tell you why.
The US joined WW1 because of the sinking of the Lusitania by the Germans. Another thing that caused US to joined that a telegram was sent to Mexico asking for them to attack US in exchange for land in Texas, California, Arizona, and Nevada

Answer 2

First off, the U.S. had nothing to do with the ignition of the first global conflict. You see, years prior to the war, Europe was known as a 'powder keg' because there were a lot of intense rivalries between the Western European industrial superpowers (notably Germany and France) and all it took was the death of one man to ignite it; the heir to the throne of the Austrian-Hungarian Empire.

The Austrians held dominion over Serbia- a state or something in Central Europe- and the Serbs sought independence from the Austrians and the popular opinion paved the way for terror cells. One of these cells took advantage of the heir's arrival in Serbia to qualm things down with the Serb/Austrian relations and the terror cell killed the heir (there is a LOT more to what went down in Sarajevo).

This INFURIATED Austria and they declared war on the Serbs. Russia backed the Serbs because they were mounting diplomatic relations with the Serbs. Germany responded to Russia by involving herself to back Austria; her good ol' buddy and Germany also declared war on France because Germany knew France would get involved sooner or later, which lead to England declaring war on Germany; thus starting WW1.

America got involved later when she vexed Germany by sitting back and making money by selling supplies, weapons, and vehicles to England and France (the war had nothing to do with America and we're capitalists, so we capitalized and helped our allies). Germany obliterated American merchant ships that lead to several American civilians being killed (they even 'accidentally' sunk American charter ships ), sabotaged the mounting U.S. military strength (the most famous one being Operation Black Tom), and the straw that broke the camel's back was the Zimmerman Telegram, which made it evident that the Germans were manipulating Mexico to wage war on America to postpone the U.S.' eventual involvement in WW1. When the telegram was brought to the American public, it influenced Americans to wage war on Germany and that's how America got involved in the summer of 1917.

Isn't World War 1 cool?
