World War I started in central Europe on July 1914. There were four causes to the war. They were militarism, alliances, imperialism, and nationalism. Militarism was when the army and military forces were given a high profile by the government. An alliance is an agreement made between two or more countries to give each other help if it`s needed. Imperialism is when a country takes over new lands or territories and makes them subjects to their ruler. Nationalism means being a strong supporter of the rights and interests of one's country. The event that sparked the war was the Assassination of Archduke Franz Ferdinand of Austria and his wife.
The two main reasons that he United States entered World War I was the sinking of Lusitania. On May 7, 1915 Germans sunk a U.S. cruise ship that had 159 Americans on it the rest were Europeans. There were 1, 959 people aboard the ship that day. The Lusitania was sunk on the coast of Southern Ireland. The second reason why the United States entered World War I was because of the Zimmerman note. In that note Germany had went overboard about the war. They had promised Mexico they would help get back the states of Texas, New Mexico, and Arizona the land they lost.
The peace settlement of World War I was Treaty of Versailles. President Wilson fourteen points are to open covenants of peace, freedom of the seas, to have and affording approval grantees policy, an independent Polish state. The Treaty of Versailles was one of the peace treaties that ended World War I. It ended war between Germany and the Allied States the treaty was signed June 28, 1919. The U.S. rejected the fact of being about of the alliances in Europe so they returned to isolation. I think that the peace settlement wasn’t a long lasting use because the League of Nations.
