Answer: What is International History Olympiad mean?

The International History Olympiad is a competition for top history students from around the world which debuted in 2015. The International History Olympiad was founded and is overseen by International Academic Competitions (IAC), though prior participation in IAC events (such as the National History Bee and Bowl or International History Bee and Bowl), is not required for students to attend the Olympiad. The qualification process, events, and awards structure at the International History Olympiad are markedly different from the International Science Olympiads. Attending the International History Olympiad in person is open to students age 10-19. University students may also now compete online in the various Olympiad History Bee and Bowl quiz tournaments; these run at precisely the same times that the events do in person at the Olympiad venue. Students compete in five separate age ranges: Collegiate, Varsity, Junior Varsity, Middle School, and Elementary as is the case at other IAC events. On April 21, 2021 it was announced that the 2022 International History Olympiad will be held at Université Laval in Quebec City, Canada from July 25 to August 1, 2022.
