Researchers testified the existence of first Tagalog around Laguna De Bay who came some 8000 years back. Their artifacts made of ceramics showed that the natives fought against the Chinese and Arabs long before the Spaniards came.
The Spaniards aimed to spread Christianity and to conquer nations for Spain. Morong was the first town reached by the Spaniards on January 16, 1572. The Franciscans, first missionary group who arrived at Manila on 1577 were the same group whom Christianized Morong and the towns along Laguna de Bay like Angono, Binangonan, Cardona, Baras, Pililia, Tanay and Jalajala. Natives were baptized and catechized so "visitas" were built and with the increase of population, "parokya" or "parishes" were built. Binangonan was believed to have became one, when it separated from Morong on 1621. The name Binangonan came from the words "Ang lugar na Binangunan ng Bayan " Spaniards and Americans has influenced religious, politics, culture and education of the natives.
On March 29, 1900, Binangonan became a town or municipality under Executive Order no. 40 under American Regime.
