The International History Bee and Bowl is the counterpart to NHBB outside the USA. As of 2021-2022, IHBB runs tournaments in over 25 countries around the world, with separate divisions for Asia, Europe, Canada, and Australia and New Zealand. Divisions in Africa and the Caribbean are being launched in 2022 as well.

All IHBB tournaments feature a Bee and a Bowl, just like standard NHBB Varsity and Junior Varsity level tournaments. IHBB also features Middle School, Junior Varsity, and Varsity divisions, just like NHBB. The question content varies somewhat depending on which part of the world the tournament occurs in, and is much less focused on American history than at NHBB tournaments. All IHBB tournaments are held in English. If you know students outside the USA who would be interested in competing, or if you ever attend a foreign school yourself, IHBB is a chance to keep competing around the world!
