Dieppe
First recorded as a small fishing settlement in 1030, Dieppe was an important prize fought over during the Hundred Years' War.
Dieppe housed the most advanced French school of cartography in the 16th century. Two of France's best navigators, Michel le Vasseur and his brother Thomas le Vasseur, lived in Dieppe when they were recruited to join the expedition of René Goulaine de Laudonnière which departed Le Havre for Florida on April 20, 1564. The expedition resulted in the construction of Fort Caroline, the first French colony in the New World. Another expedition two years before where Goulaine de Laudonnière was under command of Jean Ribault, a local Huguenot captain, had resulted in the foundation of Charlesfort, now in South Carolina. Dieppe was the premier port of the kingdom in the 17th century.
On July 23, 1632, 300 colonists heading to New France departed from Dieppe.
At the Revocation of the Edict of Nantes in 1685, Dieppe lost 3,000 of its Huguenot citizens, who fled abroad.
Sayabec
The territory was historically occupied by Mi'kmaq people, a First Nation who occupied much of the Gaspe Peninsula. Its first French Canadian inhabitant was Pierre Brochu, who came in 1833. At the end of the 19th century settlers began to come in the region to work in sawmills. The municipality was first officially created in 1887 as a school municipality under the name Sainte-Marie-de-Sayabec. The catholic parish was erected in 1894. In 1917, the village of Saindon was created, and it took the name of Sayabec in 1951. Today municipality was formed in 1982 through the merger of the parish municipality of Sainte-Marie-de-Sayabec and the village municipality of Sayabec.
