Trench Warfare
Trench warfare is a type of land warfare using occupied fighting lines consisting largely of trenches, in which troops are significantly protected from the enemy's small arms fire and are substantially sheltered from artillery. I have no clue how this contributed to America joined the war, because it was just a tactic. -
Sinking of Lusitania
The sinking of the Cunard ocean liner RMS Lusitania occurred during the World War 1, as Germany waged submarine warfare against the United Kingdom which had implemented a naval blockade of Germany. It helped bring America in because it killed a bunch of their innocent people. -
Zimmerman Note
The German tried to send this code to Mexico to try and get them to join and help them fight against America before they were even in the war. America got triggered. -
Spanish Flu
An unusually severe and deadly strain of avian influenza, a viral infectious disease, that killed some 50 million to 100 million people worldwide over about a year in 1918 and 1919 -
Fourteen Points
In this address to Congress, President Woodrow Wilson proposed a 14-point program for world peace. These points were later taken as the basis for peace negotiations at the end of the war. -
Espionage and Sedition Acts
These acts targeted anyone who spoke of war. It violated the first amendment because it took away from freedom of speech. The Schenck vs United States court case took place, where Supreme Court ruled that that the freedom of speech protection afforded in the U.S. Constitution's First Amendment could be restricted if the words spoken or printed represented to society a “clear and present danger." -
Women at Work
During the war, large numbers of women were recruited into jobs vacated by men who had gone to fight in the war. New jobs were also created as part of the war effort. The 19th Amendment gave women the right to vote and have jobs, opening this up. -
Treaty of Versailles
The Treaty of Versailles was the most important of the peace treaties that brought World War I to an end. The Treaty ended the state of war between Germany and the Allied Powers. Germany had to pay to repair all the damage of the war. To the victors, it seemed fair. Germany had caused – and in Clause 231 had accepted the blame for – the war.
