Why did the biak na bato fail?

The Biak-na-Bato Republic failed primarily due to internal divisions and lack of sustained support. While it initially aimed to establish independence from Spanish colonial rule, infighting among revolutionary factions weakened its effectiveness. Additionally, the Spanish government offered amnesty and concessions, which led some leaders to accept peace negotiations, ultimately undermining the movement's momentum. The lack of resources and military strength further contributed to its inability to maintain independence.
