The war fostered influenza in the crowded conditions of military camps in the United States and in the trenches of the Western Front in Europe. The virus traveled with military personnel from camp to camp and across the Atlantic, and at the height of the American military involvement in the war, September-November 1918, influenza and pneumonia sickened 20%-40% of U.S. Army and Navy personnel. These high morbidity rates interfered with induction and training schedules in the United States and rendered hundreds of thousands of military personnel non-effective.
Christopher Columbus was an Italian explorer who was responsible for opening the "New World" to European colonization in 1492. This was the first contact that Europe had had with the Caribbean, Central and South America. Columbus's voyages were sponsored by the Catholic Kings of Spain, Isabella and Ferdinand.
When Columbus undertook these trips, he made some promises to the Kings in order to guarantee their support. Columbus promised that he would <u>bring back gold, spices, and silks from the Far East; spread Christianity; and lead an expedition to China.</u>
Many colonists were unhappy because they did not have self government, this meant that they could not govern themselves and make their own laws.
