In 2018, UNT History Professor Andrew Torget set a Guinness World Record for the World's Longest History Lesson. Dr. Torget's record-breaking lesson lasted 26.5 hours, covered Texas history from prehistory through the Great Depression, and raised funds to support The Portal to Texas History. The Portal has archived the entire lesson online, divided into units of about an hour or less for easy viewing. The links to each unit are listed below, along with the topics covered in each unit.
