Inhabitants of Peumerit are called Peumeritois in French.
History
Modern period
This municipality is known for events related to the revolt of the "bonnets rouges," translated as the red caps, in 1675. In 1759, an order from Louis XV required the parish of Peumerit to provide 20 men and pay 131 livres for "the annual expense of the coastguard of Brittany."
French Revolution
The parish of Peumerit, which included 140 households, elected two delegates, Alain Le Brun and Pierre Canevet, to represent it at the Third Estate assembly of the seneschal of Quimper in the spring of 1789.
The 20th Century
The expulsion of the clergy from the Peumerit Parish on 11 March 1909 led M. Duparc to ban all religious bell ringing, including for the Angélus and funerals. A priest stationed at the presbytery of Treogat was assigned the responsibility of visiting the sick, conducting funerals, and administering the sacraments.
