Ma-i was a medieval state first recorded in Chinese documents, such as the History of Song and the Zhu Fan Zhi (1225) by Zhao Rukuo. Ma-i was described to be located north of Borneo, and were highly competitive in the trade with China. While the exact location of Ma-i remains disputed, most historians agree that it was located in Mindoro, specifically at the Mauhaw River around Bulalacao according to William Henry Scott. This is corroborated by Spanish records, such as the account of Juan Francisco de San Antonio, called the Chronicas de N.S.P. Francisco en las Islas Filipinas, China y Japón 1738, where Chapter 36 of the book is called De la Provincia y Isla de Mait o Mindoro ("The Province of the Island of Mait or Mindoro"), showing that the term Mait and Mindoro were once interchangeable.
Historical records in the National Archives of the Philippines have shown Bulalacao engaging in barangay network trade alliance with neighboring polities. Colonial documents point to this fact. Evidence shows that Nicolás Contreras, the ruler of Bulalacao, along with his vassal maginoó, entered into alliances with the ruler of Mansalay and their subject maginoó, in trade agreements with the Spanish colonial government in Manila.
Since at least the 1700s, Bulalacao has been ruled by the Contreras clan as the Panginoón Basal. The clan is one of a few Filipino families with clear descent from ancient maginoó lineage.
In the early 19th century, Datu Calido of Panay was in control of Bulalacao. Following the expansion of the settlement, it was ruled by the capitanes. They were Gabriel Contreras as Gobernadorcillo, with vassal datu: Paigao, Jacinto Pajado and Narciso Pandino. They ruled the area until the arrival of Lieutenant Morris in 1903. In 1906, the settlement became a township which included Paclasan, Mansalay, Mangaring, and the islands of Caluya, Sibay and Semirara.
On May 7, 1995, re-electionist Mayor Guillermo Salas was assassinated a day before the midterm elections by Rodel Gonzáles of the Mangyan tribe; Gonzáles eventually surrendered to authorities five days later and confessed to the crime.
Bulalacao is located at the southernmost tip of the province and is from the provincial capital Calapan and from Roxas.
