The influx of settlers from the neighboring islands of Guimaras, Panay and Cebu prompted the then Governor Saravia to create an additional town which is now Pulupandan.

The settlers made this town a landing area in coming to Negros, brought about by the introduction of sugar which resulted in the economic growth and prosperity of the island.

Significant events in the province during the early founding years as well as major upheavals during and after the revolutionary period brought profound changes in the municipality.

By and large, Valladolid has its place in the historical set-up of the province of Negros Occidental socially, spiritually, economically and politically.

This dominant sect caused the defeat of the fiery Manuel L. Quezon in the hands of the Aglipayans in the presidential election of 1935 during the Commonwealth era.

Valladolid is bounded on the north by the town of Pulupandan, on the south by the municipality of San Enrique, on the west by the Guimaras Strait, and on the east by the city of La Carlota.
