The International Congress of Byzantine Studies is the world’s largest academic event dedicated to the latest research and findings on the Byzantine Empire, its history, and culture. Since the first congress in 1924 in Bucharest, it has been held approximately every five years in different locations, attracting up to 1,500 participants in recent years. In 2026, the 25th Congress will take place in Vienna, where researchers from around the globe will present their work in hundreds of presentations. Cultural events and receptions will offer numerous opportunities for informal exchange. Exhibitions and collaborations with the city of Vienna and individual cultural institutions will also make the academic research accessible to a wider audience.
