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' division, which is further subdivided into the men's tournament, for male collegiate players, and the women's tournament for female collegiate players. The other division is the high school division which is also subdivided into two tournaments for the male and female high school athletes.
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 is the most coveted title that schools aspire for during a UAAP season and is one of the most anticipated live TV sporting events in the Philippines, but such aspirations have resulted in many controversies in the association. There are protests filed by the member-schools against one another almost every season. Ironically, the association has a handbook of its rules and regulations.
