Ambrosio Rianzares Bautista , also known as Don Bosyong, was a lawyer and author of the Declaration of Philippine Independence. A distant relative of the Rizal family, Bautista frequently provided advice to Philippine national hero Jos Rizal during his school days in Manila.
Bautista was born in Bian, Laguna to Gregorio Enriquez and Bautista Silvestra Altamira. He attended preparatory school in Bian and studied law at the University of Santo Tomas , obtaining a degree in 1865. He then practiced law in Manila and offered free legal services to poor clients. Whilst practicing law, Bautista, on his way to Malolos, Bulacan, was captured by a group of bandits, who subsequently learned that he had saved many of their friends as a defender of the poor in court cases against rich Filipinos and Spaniards. The bandits apologized to Bautista and set him free.
