Laguna was one of the eight provinces to rise in revolt against the Spanish misrule led by Generals Paciano Rizal in Calamba, Severino Taiño in Pagsanjan, Agueda Kahabagan in Calauan, and Miguel Malvar in Batangas. One of the early engagements of the revolution was the Battle of Sambat, in Pagsanjan. Katipuneros from Laguna, led by Severino Taiño, took the city of Pagsanjan and attempted to use it as a starting point towards the liberation of the province, but was quelled by forces led by Basilio Augustin.
