Carl Ferdinand Allen

Carl Ferdinand Allen (April 23, 1811 in Copenhagen – December 27, 1871) was a Danish historian. He studied at the University of Copenhagen. He spent three years (1845-1848) researching at the archives of England, France, the Netherlands, Italy and Germany; upon completion of this task, he returned to Denmark. In 1851 he became a lecturer at the University of Copenhagen and, in 1862, a professor of history and northern archaeology.

His principal work is his De Tre Nordiske Rigers Historie, 1497-1536, ("The History of the Three Northern Kingdoms," five volumes, 1864–72). He wrote the work following years of examinations of the archives of European nations.
