Nils Magnus Brahe (1790–1844) Swedish statesman, soldier and member of the Brahe comital family.
Nils Magnus Brahe was the son of Swedish Count Magnus Fredrik Brahe (1756-1826) in his first marriage with Baroness Ulrika Katarina Koskull (1759-1805). He was also a descendant of Swedish statesman Per Brahe.
After studying in the University of Uppsala, he began his professional military career. He fought in the War against Napoleon (1813–1814) under Jean Bernadotte who later ascended to the throne as Charles XIV John of Sweden (Swedish: Karl XIV Johan). He was in high favour with the French born king who had a poor command of the Swedish language. He became Marshal of the Realm, and especially from 1828 onwards, exercised an influence in public affairs. As a politician, he reportedly remained close to his stepmother, Countess Aurora Wilhelmina Koskull, who was active within Stockholm aristocratic circles. In 1837, he was elected a member of the Royal Swedish Academy of Sciences. This article incorporates text from a publication now in the public domain: Chisholm, Hugh, ed. (1911). "Brahe, Per".
