The inaugural International Geography Bee World Championships were held on July 11-17, 2018 in Berlin, Germany with events being held at the Berlin Brandenburg International School (on July 15-17) and around Berlin. It was (and in the future, always will be) possible to compete in both the International History Olympiad and the IGB World Championships if students are qualified for both.
Three separate events: the Intl. Geography Exam, the Intl. Geography Showdown, and the Intl. Geography Quiz together constituted the official 2018 IGB World Championship title. As is the case at the International History Olympiad, students from the USA competed for their home states unless they have a foreign passport and wished to compete for their country of citizenship.
