a French bishop of Strasbourg, politician, cardinal of the Roman Catholic Church, and cadet of the Rohan family (which traced its origin to the kings of Brittany). His parents were Hercule Mériadec, Prince of Guéméné and Louise Gabrielle Julie de Rohan. He was born in Paris.
Members of the Rohan family had filled the office of Bishop of Strasbourg since 1704, which made them princes of the Holy Roman Empire and the compeers rather of the German prince-bishops than of the French ecclesiastics. Louis de Rohan was destined for this high office from birth.
