Dates assigned to each conflict are those that are generally regarded as the formal start and finish of each war. It should be noted that the United States did not enter the two world wars of the twentieth century until several years after those wars began. In order to provide fuller perspectives, this time line includes events that preceded U.S. involvement in several conflicts and thus includes some battles and other developments in which the United States was not directly involved.
