Hoover Institution on War, Revolution and Peace, Think tank founded in 1919 (as the Hoover War Collection) by Herbert Hoover. It is located at, but has no institutional connection with, Stanford University, in Palo Alto, California. The Hoover Library and Archives house source materials on social and political developments connected to war, revolution, and peace in the 20th and 21st centuries. Resident and visiting scholars in fields such as economics, political science, history, international relations, and law draw upon the institution’s collections for study, research, and published writing. Known for its conservative orientation, the institution promotes personal and economic liberty (i.e., free enterprise), limited government, and the safeguarding of peace.
