Our "On This Day in History" section of the website is designed to provide teachers with video resources to help students better understand significant events throughout U.S. history.

Each event features several short video clips that help set the stage by providing context through archival footage and witness testimony (where available), utilizing C-SPAN's unique access to historical newsreels, vignettes, oral history, and expert analysis.

As one of the most recent additions to our site, this area will continue to develop each month. If you or your students have suggestions for key moments in history that are not currently represented, please email us at educate@c-span.org.
