Wikipedia - UAAP basketball championships
The UAAP basketball championships are basketball tournaments held from September to December by the University Athletic Association of the Philippines, and the men's tournament is the flagship tournament of the UAAP. Basketball is a mandatory sport for all schools. All eight universities participate in the men's, women's, and high school (boys') tournaments.
History
The tournament is divided into two divisions, the collegiate (formerly seniors') division, which is further subdivided into the men's and the women's tournament, and the high school (formerly juniors'), which is subdivided into boys' and girls' tournaments.
The UAAP basketball sport has a rich history of schools establishing dynasties. UE won a record seven consecutive basketball titles from 1965 to 1971 albeit the third one was a shared championship with UST. Ateneo had a 5-year winning streak from 2008 to 2012. Two other schools ended their championship streak at four. UST won it from 1993 to 1996 and La Salle from 1998 to 2001.
The championship in basketball, with its major overall points contribution to the annual UAAP general championship tallies, is one of the most coveted titles. The boys' tournament was called the "juniors' tournament" prior to 2019. The tournament was held concurrently with the seniors' tournaments in the first semester of the academic year (July to October), until 2014, when it was moved to the second semester (November to March).
