Consecuences

• WW1 caused the downfall of four monarchies: Germany, Turkey, Austria-Hungary and Russia.
•  WW1 largely marked the end of colonialism, as the people became more nationalistic, so that made people more open to other ideologies, such as the communism on Russia.
• The war changed the economical balance of the world, leaving European countries deep in debt and making the U.S. the leading industrial power and creditor in the world.
• Due to the using of toxic chemicals, the land became unusable for years.
• With troops travelling all over the world, influenza was spread easily and an epidemic started which killed more than 25 million people across the world.
• Due to the cruel methods used during the war and the losses suffered, the Great War caused a lot of bitterness among nations, which also greatly contributed to the Second World War decades later.
• Social life also changed: women assumed the role of workers by replacing men in factories and offices, so the countries gave them more rights after the war ended, including the right to vote.
• The need for an international body of nations that promotes security and peace worldwide caused the founding of the League of Nations.
