The Warlord Chronicles is a trilogy of books about Arthurian Britain written by Bernard Cornwell. The story is written as a mixture of historical fiction and Arthurian mythology.
Like other "historical" takes on the Arthurian legends, the series postulates that Post-Roman Britain was a difficult time for the native Britons, being threatened by invasion from the Anglo-Saxons in the East and raids from the Irish in the West. At the same time, they suffered internal power struggles between their petty kingdoms
