In 1917, an extremely important historical event occurred: the entry of the United States into the conflict. The United States joined the Triple Entente, as there were trade agreements to defend, mainly with England and France.
This fact marked the Entente's victory, forcing Alliance countries to sign the surrender. The defeated had yet to sign the Treaty of Versailles, which imposed strong restrictions and punishments on these countries. Germany had its army reduced, its arms industry controlled, it lost the region of the Polish corridor, it had to return the region of Alsace Lorraine to France, in addition to having to pay the war losses of the winning countries. The Versailles Treaty had repercussions in Germany, influencing the beginning of the Second World War.
