WWI

  • Development of Alliances

    World War I was a conflict between the Allies, composed of 18 nations, and the Central Powers, which were Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. The triple alliance was composed of Germany, Austria-Hungary, and Italy. The triple entente was formed to challenge the triple alliance. Russia, France, and Great Britain.
  • Austria Declares War on Serbia

    After the assassination of their Archduke led Austria-Hungary to declare war on Serbia and Bosnia. The conflict between these two led to other countries having to take sides. These two sides became the two sides in WWI.
  • The First Battle of the Marne

    This was the first official battle of The Great War on the Western Front. It resulted in a victory for the Allied Powers. The Germans' Schlieffen plan was ruined because of this battle.
  • The Assassination of Archduke Franz Ferdinand

    Archduke Franz Ferdinand, heir to the Austrio-Hungarian throne, was killed by Serbian assassins. Their objective was to be able to free Austria-Hungary's South Slav provinces (Bosnia, Herzegovina, Bulgaria, Croatia, Macedonia, Montenegro, Serbia, Slovenia) and combine them to form Yugoslavia.
  • Stalemate on the Western Front

    Because the Schliffen plan had failed for the Germans, they started to build trenches to fight in. The other countries followed suit and fought them in their own trenches. At first, neither side was able to gain any ground on the other because they both had the same technology, meaning everything they did could be done right back to them.
  • Sinking of the Lusitania

    Germans used U-boats to shoot torpedoes at the RMS Lusitania, a luxury liner containing English people and Americans. This led to outrage in England and America, eventually leading America to declare war on Germany.
  • Technology in WWI

    One new technology in WWI was mustard gas, a poisonous gas that was thrown into trenches and led to death when inhaled. Machine guns were helpful because they could inflict damage on many people in a shorter amount of time. England's use of tanks was what broke the stalemate in the trenches.
  • The Russian Revolution

    Russian citizens were sick of Czar Nicholas II's authoritarian way of governing. The Czarist regime was taken over by bolsheviks, representatives of the social democratic party. This party was later renamed the Communist party.
  • America Joins the War

    America was first provoked by the sinking of the Lusitania because it had American citizens and English citizens. However, they eventually joined because of something that came to be known as the Zimmerman telegram. This was a telegram sent by Germany for Mexico proposing an alliance between them in case of war against the US. British intelligence intercepted the telegram and shared it with Woodrow Wilson, who made it public and congress decided to go to war.
  • Armistice

    Germany was out of all resources and was surely going to be invaded and conquered, so they had to sign an armistice conceding to the Allies. The Germans were the clear big losers of this war.
