By 1896 the Katipunan had a membership by the thousands. That same year, the existence of the Katipunan was discovered by the colonial authorities.

The event is now known as the Cry of Balintawak or Cry of Pugad Lawin, due to conflicting historical traditions and official government positions.[39]
