There is no specific event called the "International Convention in Black history." However, there are international conferences and gatherings focused on Black history and African diaspora studies. One prominent event is the Association for the Study of African American Life and History (ASALH) Annual Meeting and Conference, which brings together scholars, educators, and community members to discuss and celebrate Black history and culture.

Another significant international conference is the International Conference of the Historical Society of Nigeria (HSN), which covers a wide range of topics in African history, including Black history.

Overall, these gatherings serve as important platforms for sharing research, promoting dialogue, and advancing the study and understanding of Black history on a global scale.
