This powerpoint gives an excellent overview of the major events of 20th Century American History: WWI, WWII, the Great Depression, the Civil Rights Movement, political assassinations, the Cold War, the Vietnam War, etc. Can be used in an American History, World History, Government or Civics class. A follow-up activity would be to assign each student a different event and have them do a report, make a poster, etc. Great also for class discussions.
