In June 1583, several villages were formally
declared as a "doctrina" during a Franciscan Chapter meeting conducted by
Fray Pablo de Jesus. A "doctrina" is said to be Franciscan ecclesiastical
terminology which is similar with the term "convento".
Among these convento was included the town of
Bula which according to historical documents, the said town "received a
regular religious instructions" from the missionaries. This accounted to the
fact that the municipality is among the oldest parishes founded by the
Franciscan missionaries.
In 1829, the town was among the towns
included under the District of Rinconada.
Literally, the name Bula means "bamboo split"
which actually is taken from a local dialect, bala. During the ancient
times, these bamboo splits were utilized as firewood, fish traps and other
crafts made out of this plant. Because the town has an abundant supply of
bamboo, it was for many years considered to be the prime supplier of this
commodity.
