Isaac de Razilly (1587–1635)[1] was a member of the French nobility appointed a knight of the Order of St. John of Jerusalem at the age of 18.
In 1624, he was put in charge of an embassy to the pirate harbour of Salé in Morocco, in order to solve the affair of the library of Mulay Zidan.
[3] As Richelieu and Père Joseph were attempting to establish a colonial policy, Razilly suggested them to occupy Mogador (Essaouira) in Morocco in 1626.
He departed for Salé on 20 July 1629 with a fleet composed of the ships Licorne, Saint-Louis, Griffon, Catherine, Hambourg, Sainte-Anne, Saint-Jean.
Razilly landed at La Hève, now LaHave, Nova Scotia, with 300 men and 3 monks and built Fort Sainte Marie de Grace.
As well, he took on military tasks such as ordering the taking of control of Fort Pentagouet at Majabigwaduce on the Penobscot Bay, which had been given to France in an earlier Treaty, and to inform the English they were to vacate all lands North of Pemaquid.
