Key aspects of orthodox, political Britishness left C.S. Lewis very cold, despite his upbringing in an Ulster Anglican Unionist household (that is, one tied to the British-affiliated Irish Ascendancy). Lewis’s negative feelings regarding political Britishness led him to air strong anti-colonial views in his fiction and other writings, and to frequently disparage key (violent) figures from British history. It even led him to say quite negative things about Orangeism, as it manifested itself in his native Ulster. As someone from the “Celtic Fringe” who loved his native Ireland and who was very proud of his Welsh ancestry, Lewis especially resented the primacy of England within the British scheme. He therefore created works throughout his career that sought to redefine what is popularly understood by the word “British.” Specifically, he promoted a cultural Britishness that treated all four nations in the British scheme equally—and that also left more room for smaller, often overlooked parts of the “Celtic Fringe,” such as Cornwall and the Isle of Man. This aspect of Lewis’s work anticipates the efforts of historians and cultural critics of the post-1990s “Four Nations” school.
