Knutsen Magnus Falsen, a Norwegian historian, born at Opslo, Sept. 17, 1782, died in Christiania, Jan. 13, 1830. He was a son of the poet Enevold von Falsen, was educated in Copenhagen, became a lawyer and judge in Norway, and was a member of the constituent diet of Eidsvold (1814), and deputy to the storthing (1815-22). He voluntarily gave up his title of nobility, but became unpopular in 1822, when, as attorney general, he defended such measures of the government as conflicted with his formerly enunciated views. The storthing in 1824 withdrew the appropriation for his office, upon which the king appointed him governor of Bergen, and in 1827 he removed to Christiania as justice of the supreme court. His principal work is Norges Historie (4 vols., Christiania, 1823-,4).
