Captain Britain debuted in the first issue of Captain Britain Weekly (cover-dated the week ending 13 October 1976), an anthology comic published exclusively in the United Kingdom by the Marvel Comics imprint known as Marvel UK. The comic represented the first original content published by Marvel UK, who had previously only handled reprints of Marvel Comics' U.S. publications. However, the new content was still created by Marvel's American staff (the initial team being London -born writer Chris Claremont, penciller Herb Trimpe, and inker Fred Kida) under the supervision of U.S. editor Larry Lieber, then shipped to the UK for publication. (In addition, the new 8-page Captain Britain installments in each issue of Captain Britain Weekly were supplemented by more reprinted material, featuring Nick Fury and the Fantastic Four).
