Marilao ([mɐɾiˈlaʊ]), officially the Municipality of Marilao, is a vibrant municipality located in the province of Bulacan, Philippines. As of the 2020 census, it boasts a population of 254,453 people.

Etymology

The name "Marilao" is rooted in the Tagalog word "marilaw," meaning "yellowish." This term is directly linked to "dilaw," the Tagalog word for "yellow." The name came about due to the abundance of a distinctive yellow plant that thrived in the area.

Early History and Establishment

Marilao's origins trace back to its time as a barrio of the neighboring town of Meycauayan. Franciscan missionaries from Meycauayan played a significant role in its early development, constructing a visita (chapel) dedicated to Saint Michael the Archangel within the barrio.

On April 21, 1796, the Barrio of Marilao officially transitioned into a pueblo (town). This establishment received approval from the Alcalde Mayor of Bulacan and the Franciscan friars of Meycauayan, with the consent of the Archbishop of Manila. The visita of San Miguel Arcangel was then elevated to a town church, with Padre Vicente de Talavera serving as its first parish priest. Interestingly, the very first church in Marilao was built approximately 50 years prior to its official town status, at a location known as "tawiran," which is now the site of the old chapel, "bisitang matanda."

Periods of Change and Independence

Marilao's journey to full independence wasn't straightforward. On February 27, 1901, the town briefly reverted to being a barrio of Meycauayan. However, it wasn't until 1913 that Marilao finally achieved complete independence as a municipality.

Marilao also played a part in the development of the country's infrastructure, becoming a segment of the railroad track that connected Manila to Dagupan, Pangasinan. This significant railway line was completed on March 24, 1889.
