Welcome to the Tree. This is a community-driven project designed to chronicle the history and generations of BJJ practitioners from the very beginning with Mitsuyo "Count Koma" Maeda all the way up to the present day. We would like to invite all BJJ practitioners (regardless of rank) to add themselves to the tree as well as any missing black belts they may know of. Users are also encouraged to submit changes to existing players if they see something is incorrect. We hope, through the efforts of the community, to make this the most accurate, complete and prolific record of BJJ players on the web.
