After the end of World War II in Europe, the discovery of the Nazis' Black Book in September 1945 showed that all the group's members were to be arrested as soon as Britain had been invaded by the Axis. Lady Astor remarked, "It is the complete answer to the terrible lie that the so-called 'Cliveden Set' was pro-Fascist."[2]
New research shows that the Astors invited a very wide range of guests, including socialists, communists and enemies of appeasement. Scholars no longer claim there was any Cliveden conspiracy. Historian Andrew Roberts says: "The myth of Cliveden being a nest of appeasers, let alone pro-Nazis, is exploded."[3] Norman Rose's 2000 account of the group rejects the conspiracy theory of a pro-Nazi cabal. Carroll Quigley argues against the "mistaken idea" that the Cliveden group was pro-German: "They were neither anti-German in 1910 nor Pro-German in 1938, but pro-Empire all the time."[4]
Christopher Sykes, in a sympathetic 1972 biography of Nancy Astor, argued that the entire story about the Cliveden Set had been an ideologically motivated fabrication by Cockburn that came to be generally accepted by the public, which was looking for scapegoats for the British prewar appeasement of Adolf Hitler. Some academic arguments have stated that Cockburn's account may have not have been entirely accurate, but that his main allegations cannot be easily dismissed.[5][6]
In the fourth and fifth episodes of season six of the 1960s sitcom Hogan's Heroes, the two-part episode "Lady Chitterly's Lover" involves a plot to negotiate Britain's surrender from a fictitious member of the Cliveden Set, Sir Charles Chitterly. While this is based on no direct historical counterpart, it does incorporate – among other events – elements of the visit to Nazi Germany in the late 1930s of the former British King Edward VIII after he had abdicated the throne in 1936 and settled into exile in France.
The Remains of the Day
Lord Darlington, the fictional secondary protagonist in Nobel Prize-winning British author Sir Kazuo Ishiguro's 1989 novel The Remains of the Day is based on an amalgamation of several of the more prominent members of the Cliveden Set, some of whom are listed above. The novel was turned into the 1993 film of the same name which was nominated for eight Academy Awards and six BAFTA Awards, including a BAFTA win for Sir Anthony Hopkins in the Best Actor category. The social gatherings that are held at the fictional Darlington Hall in the film between Nazis and British subjects seeking peace and being manipulated by the Nazi representatives are based on several dinner parties and other social gatherings that were held by the Cliveden Set.
