Causes of WWI

World War I, also known as "The Great War" was not named World War I until after World War II. Militarism was was a major cause in the war since countries started spending loads of money on the military. Soon alliances such as the tripple alliance were formed and that caused a mojor threat to other countries. Of course the assination of Austria-Hungary's Archduke Franz Fernidad was a major cause of WWI.

After the assination of Archduke Franz Fernidad, countries that were allies with another country joined the war. Soon there were so many countries involved in the war that it became the first world war. World War I was also called the trench war, from all the trenches that were made and used during the war. The Americans only joined the fight against the triple alliance after they were suddenly attacked, just like in World War II.
