It reviews all of the substantive material that is usually taught in the second semester of the two-semester course in the United States history. Our goal as creators of this course is to prepare you to pass the College Board’s CLEP examination and obtain college credit for free.

Through the guidance of Dr. Stephen Sullivan, this course will cover the period of United States history from the end of the Civil War to the present, with the majority of the questions being on the twentieth century.

“History of the United States II: 1865 to the Present” is a completely self-paced course. It has no prerequisites and it is offered entirely for free.


  • Stephen Sullivan, Ph.D.

    Dr. Stephen Sullivan is a historian of the United States. A protege of noted Columbia historians Eric Foner and Kenneth Jackson, Sullivan's research interests include women's history, labor history and urban history, especially as they relate to New York City and Brooklyn; as well as immigration and ethnicity, with a sub-specialty in Irish-America. However, his interests are rather eclectic.

    Current projects include revising his dissertation into a book manuscript for Catholic University of America Press (Social & Spatial History of Irish-Americans in The City of Homes from the Great Hunger through the Great War), a journal article examining the development of nineteenth century labor cooperatives in New York City; and a coauthored children's book (Table Talk: How Family Dinners Can Help Stop Unhealthy Eating Patterns) for the APA's Magination Press about the positive impact of tweens sharing family meals. Dr. Sullivan has taught at several universities, most notably his alma mater, Columbia University (The History of the City of New York).

    He has also taught at Barnard College (Immigrant Women in the Empire City), Adelphi University (The History of the City of New York; American Civilization to 1877; Civil War & Reconstruction), CUNY-Hunter College (United States History I & II) and Nassau Community College (Introduction to American Government). The veteran educator has taught Advanced Placement American History and Behavioral Science Research at Lawrence High School in Cedarhurst, NY for three decades.

    A long list of organizations have honored Dr. Sullivan for instructional or mentoring excellence - the Organization of American Historians, the American Historical Society, the Association for Psychological Science, the American Association of Geographers, the American Psychological Association, the Walt Disney American Teachers Awards Committee, the National Teachers Hall of Fame, the New York State Union of Teachers, the Long Island Council of Social Studies and the U.S. Department of Education. "A social history of the Brooklyn Irish, 1850-1900" was honored as a finalist in the Urban History Association's "Best Dissertation of 2013" competition.

    However, Dr. Sullivan is most proud of his work mentoring over one hundred award-winning and/or published undergraduate and precollegiate research projects in history, psychology, economics, geography and anthropology.
