Modern realism began as a serious field of research in the United States during and after World War II. This evolution was partly fueled by European war migrants like Hans Morgenthau who had a negative view of human nature, thought by some to be due to their experiences in war.

Prominent classical realists:

• George F. Kennan

• Nicholas Spykman

• Herman Kahn

• E. H. Carr

• Reinhold Niebuhr

• Hans Morgenthau

• Arnold Wolfers

• Charles Beard

• Walter Lippmann
