holding the professor chair any longer, Koht continued his academic writing; his principal work from the post-war epoch was the six-volume Kriseår i norsk historie. The six volumes each describe a decisive moment in Norwegian history. The first volume, released in 1950, centers on "Vincens Lunge contra Henrik Krummedige". The second volume (1951) describes Olav Engelbriktsson and Norway's descent into dependency to Denmark in 1537. The third and fourth volumes, released in 1952 and 1955, are about medieval kings: Sverre I and Harald I. The fifth volume (1956) focuses on "Queen Margaret and the Kalmar Union". The sixth and final volume (1960) chronicles the years from 1657 to 1661, when Denmark (and thus Norway) transitioned into an absolute monarchy. Koht died on 12 December 1965 in Bærum. He was buried at Nordre gravlund in Oslo. Two works by Koht have been released posthumously: the memoirs Minne frå unge år in 1968 and the diary Rikspolitisk dagbok 1933–1940 in 1985. His son-in-law Sigmund Skard wrote a biography of him, Mennesket Halvdan Koht ("Halvdan Koht the Man") in 1982.
