Some centuries after, the Muslims (trying to reach the Northern part of Spain) transformed the place, and renamed it as "Bericulos."

After the ejection of the Moors, Peligros' population suffered a decline to a hundred of inhabitants, and its development took place during the 18th century.

When the Reconquest finished and the settlement of the owners was normalized at their respective places, of the 20 families who returned to Peligros, 16 were of Muslim origin, the other 4 were Christians.

1.81% of the registered population is foreign (189 inhabitants), mostly from Morocco, although lately there are many Portuguese and Latin, mostly building workers.

Its economy is mainly based on agriculture (oats, melons, olive oil) and trade (with 1,221 places) that employ about 1,080 employees.
