Mindoro Island was originally known to the ancients as Ma-i. It was formally called Mait, and known to the Chinese traders before the coming of the Spanish. Its existence was mentioned in the old Chinese chronicles in 775 A.D. and more elaborately in 1225. It was a major anchorage in the Southeast Asia trade route during the pre-Philippines period. Chinese, Arab and Indian merchants traded with the natives. In 1570, the Spanish began to explore the island and named it Mina de Oro (“mine of gold”) after finding some of the precious metal, though no major gold discoveries were ever made.

The natives of Mindoro were called Manguianes by the Spaniards. But the natives refer to themselves by their ethnic or clan identification. There were seven such ethnic or clan distinctions, which are differentiated by language and areas where each can be found.

The Mangyans, as they are now anthropologically known, do not have a warrior society. They are a peaceful, shy but friendly people. They are rarely known to be hostile, and have had no significant record of violent conflict with other people in the entire history of the province. They grow root crops in forest clearings (slash and burn farms), and hunt wild animals in the forest for their meat needs.

There are no authentic documents in existence explaining the original stock of the Mangyan people, but later theoreticians postulate that they migrated from Indonesia before 775 A.D. They hopped from island to island, until finally settling down permanently in Mindoro. It appeared that clan settlements existed in the North as well as in the southern ends of the island. By 779, the southwest coast of the island was already a known trading center, and its fine natural harbor frequented by Arab, Indian and Chinese maritime traders who plied the route. But there was no attempt of subjugation, just trading.

Republic Act No. 505, an Act to Create the Province of Occidental Mindoro and Oriental Mindoro, approved by Congress on June 30, 1950 created the Province of Occidental Mindoro and its sister province, Oriental Mindoro.

Mindoro Island, the seventh largest island in the Philippines, is contained in the quadrangle bounded by 12°9′ north , latitude 121°15′ east longitude. Occidental Mindoro is one of the two provinces compromising Mindoro Island. It is located 45km. south of Batangas and north of Visayas. The entire eastern portion of the province is bounded by Oriental Mindoro and the western portion by the Apo East Passage.

On the north, it bounded by the Calavite and Verde Island Passage and on the south by Mindoro Strait. The southernmost tip of Occidental Mindoro lies in the area of Sibuyan Sea. Like most of the provinces in the Philippines, the lack of technical description defining the boundaries of the province causes territorial dispute with its neighboring province, Oriental Mindoro.
