What is the ADCC?
Developed by Sheik Tahnoon Bin Zayed Al Nayan, the ADCC (Abu Dhabi Combat Club) holds the ADCC Submission Wrestling World Championships every year. In the search for the world's best grapplers, the World Championships is under a tournament format with different weight classes.
The ADCC competition was created by Sheik Tahnoon Bin Zayed Al Nahyan, the son of the former president of the United Arab Emirates, Sheik Zayed. A practitioner of the martial arts, which he learned while studying in the United States, Sheik Tahnoon established the ADCC upon his return home as a way to gather the best grapplers in the world and, in the process, created the Wrestling Submission World Championship.
