Institute for the American Constitutional Heritage


About

The IACH is an inter-disciplinary center for the study of American constitutionalism. The notion of a constitutional heritage reflects the Institute’s broad approach to the Constitution in all its aspects: its philosophical underpinnings, its historical context, its legal substance, and its contemporary relevance. The IACH is committed to ensuring that the University of Oklahoma is a place where students can study the ancient roots of law, liberty, and self-governance, the development of liberal and republican thought in the modern world, the historical and ideological background of the American founding, the development of civil rights in American history, and the relevance of the Constitution to contemporary debates over justice and freedom.


Events

George Washington.
Presidents' Day

Each February, the IACH invites a prominent scholar to deliver a lecture in commemoration of Presidents' Day. The purpose of the lecture is to reflect on such themes as the nature of civic leadership, the conditions for accountable government, and rhetoric and communication in modern politics. Recent Presidents' Day speakers have discussed the presidencies of Abraham Lincoln and John F. Kennedy.

Speaker Talking at Constitution Day
Constitution Day

Every September, the IACH hosts prominent scholars from around the country to deliver the Rufus Fears Lectures on Roger and Patti Clapp Constitution Day.  Federal legislation requires institutions that receive federal funding honor September 17th, the day in 1787 the Framers of the Constitution finished their business in Philadelphia.  Thanks to a gift from alumni Roger and Patti Clapp, Constitution Day at OU is named after J. Rufus Fears, a beloved Professor of Classics and Letters.

Summer Institute

Study after study shows that civic literacy and knowledge about the Constitution is at an all-time low.  The IACH is committed to addressing this crisis by hosting a summer institute for middle and high school history teachers.  Teachers read and discuss primary documents in the American constitutional tradition and receive a stipend for their participation. The teacher institute is supported by the Horizon Foundation.
