The history of San Fulgencio begins in the 18th century, when D. Luis de Belluga y Moncada, Bishop of Cartagena and Murcia, devised the possibility of drying up and populating these lands, which at that time were a focus of infection for the surrounding population, and turn them into fertile land suitable for cultivation. This project was known as “Pías Fundaciones”.

The name of the town is also owed to this Bishop, as well as that since its foundation, it has the status of Villa Real, granted by King Felipe V. Its foundation dates back to 1729.
