Pierre de Ségusson dating history

Details

Pierre de Ségusson, sieur de Longlée (c.–1592/1598) was a French noble, churchmen and ambassador during the latter French Wars of Religion. Born into a noble family of the province of Maine, Longlée entered a career in the church. By 1556 he had secured a court position as a valet de chambre, and this would be followed with the position of gentilhomme servant in 1574 at the start of the reign of Henri III. He served as the sécretaire (secretary) to the French ambassador to España the baron de Saint-Gouard for nine years, and is first attested in the role in 1574. He performed a variety of services for the ambassador during this time, and was warmly recommended to the French court by his superior. In 1579 he undertook an extraordinary mission to Portugal for the crown, to advocate for the queen mothers rights to the Portuguese throne. He would again travel to Portugal with Saint-Gouard in 1581-1582 during the crisis of the Portuguese succession, and when Saint-Gouard was relieved as ambassador at the end of 1582, Longlée was chosen to serve as his temporary replacement. His appointment would not however be temporary, despite this he would not receive the formal office of ambassador, and through his ambassadorship from 1582 to 1580 he technically held the position of 'permanent resident'.
