The Marburg Files Revealed Former British King Edward VIII’s Nazi Ties — And The U.K. Tried To Cover It Up

During World War II, Nazi officials offered to help reinstate Edward VIII to the British throne in exchange for peace with Germany in correspondence known as the Marburg Files.

Since before the start of World War II, the British Royal family’s connection to Nazi Germany has been called into question. In 1945, U.S. military forces discovered a collection of papers and telegrams, later referred to as the Marburg files, that made the connection even harder to ignore.

There is arguably no other British monarch more tied to the Nazis than Edward VIII, the former king and Duke of Windsor.

His trip with his new bride, Wallis Simpson, to visit Adolf Hitler in Germany in 1937 was only the tip of the iceberg. The Marburg files would reveal several devastating claims that connected the Duke to the Nazis in ways that his country would later find shameful enough to conceal from their public.

King Edward VIII Abdicates The Throne

Edward, the eldest child of King George V and Queen Mary, became king of the United Kingdom on January 20, 1936 following the death of his father.

But even before this, Edward had met a woman who would set off a chain of events that would change the British monarchy forever.

In 1930, then-prince Edward met an American divorcee named Wallis Simpson. They were members of the same social circles and by 1934, the prince had fallen head over heels in love.

But the Church of England — which Prince Edward was poised to become the head of when he became king — did not allow for a British monarch to marry someone who was already divorced.

Unable to rule without the woman he loved by his side, King Edward VIII made history on December 10, 1936, when he abdicated the throne in order to marry Wallis Simpson.

“I have found it impossible to carry the heavy burden of responsibility and to discharge my duties as King as I would wish to do without the help and support of the woman I love,” Edward said in a public address whereupon he announced he would not continue as King.

Edward, now demoted to the Duke of Windsor, married Simpson on June 3, 1937, in France. The pair lived there but made frequent trips to other European countries, including an October 1937 visit to Germany where they were treated as honored guests of Nazi officials and spent time with Adolf Hitler.

This was the first in a long string of incidents that linked the Duke to Hitler and the Nazis, causing a huge rift between the duke and his family.

Rumors that the former king was a Nazi sympathizer ran rampant across the world. Once World War II officially began, the Duke became a liability to his family.

Once France fell under Nazi control, the Duke and Duchess traveled to Madrid where the Germans attempted to use them as pawns in an ill-fated plan to gain control of the British government. The details of this plan and the Duke’s ties to Nazi Germany would later be revealed in the Marburg files.

The Marburg Files And Operation Willi

The Marburg files are a collection of top-secret German records made up of more than 400 tons of archives from the Foreign Minister of Nazi Germany, Joachim von Ribbentrop.

The files were originally discovered by American troops at Schloss Marburg in Germany in May of 1945. All of the material was taken to Marburg Castle to be examined and after further inspection, the U.S. forces discovered that roughly 60 pages of the material contained information and correspondence between the Duke of Windsor and Nazi Germany. These documents consequently became known as the Windsor File.

The Windsor File provided definitive evidence of the Duke of Windsor’s relationship with high-ranking Nazi officials and increased the suspicion that he was a Nazi sympathizer. One of the most shocking pieces of information that came out of the Marburg files was the detailed description of Germany’s plan known as Operation Willi.

This was an ultimately unsuccessful plan by the Germans to kidnap the Duke and Duchess of Windsor and entice him to work alongside Hitler and the Nazis to either achieve peace between Britain and Germany or reinstate the Duke as Britain’s king with the Duchess by his side.

The Germans believed the Duke a more ambivalent ally than his brother King George VI. Consequently, they plotted to lure the ostracized former monarch over to the Nazi side and even attempted to convince the Duke that his brother planned to have him assassinated.

In the book Operation Willi: The Plot to Kidnap the Duke of Windsor, Michael Bloch describes the details of the plan that included kidnapping the Duke and Duchess while they were leaving Europe to travel to Bermuda where he had just been named governor.

The telegrams revealed in the Marburg files claim that the Duke and Duchess were clued in on the Nazis’ plan to reinstate the Duke as the king and that the Duchess was a fan of the idea.

“Both seem to be completely bound up in formalistic ways of thought since they replied that according to British constitution this was not possible after abdication,” one telegram read.

“When [an] agent then remarked the course of war may produce changes even in the British constitution the Duchess, in particular, became very thoughtful.”

In another telegram, statements allegedly made by the Duke himself said that he was “convinced that had he remained on throne war would have been avoided.” The papers went onto say that the Duke was “a firm supporter of a peaceful compromise with Germany.”

Yet another damning piece of evidence read that the “Duke believes with certainty that continued heavy bombing will make England ready for peace.” 

Winston Churchill and the crown together made an effort to suppress this information.

Netflix’s The Crown Covers The Incident

The Marburg files were featured in episode six, season two of Netflix’s The Crown. The episode is titled “Vergangenheit” which is German for “past.” Claire Foy, as Queen Elizabeth II, in the episode reacts to the discovery of her uncle’s correspondence with Nazis.

The episode also details how the British monarchy and government sought to alleviate the situation.

The British Prime Minister at the time, Winston Churchill, wanted “to destroy all traces” of the Nazi telegrams and their plans to reinstate Edward as king. Churchill believed that the captured German telegrams were “tendentious and unreliable.”

Churchill feared that if the files were released they would send a misleading message to people that the Duke “was in close touch with German agents and was listening to suggestions that were disloyal.”

He, therefore, pleaded with then-U.S. President Dwight D. Eisenhower to not release the Windsor section of the Marburg files for “at least 10 or 20 years.”

Eisenhower accepted Churchill’s request to suppress the files. U.S. intelligence also chose to believe that the Windsor File was not a flattering depiction of the Duke. The correspondence between the Duke and the Nazis were “obviously concocted with some idea of promoting German propaganda and weakening western resistance” and U.S. intelligence added that the files were “totally unfair.”

When the telegrams were eventually made public in 1957, the Duke denounced their claims and called the files’ contents “complete fabrications.”

Had Edward had maintained his position as king, would he have supported the Nazis instead of the Allies? No one can possibly know what would have happened had Edward VIII not abdicated. But if the ex-king truly was a Nazi sympathizer and remained on the throne, the world as we know it might not exist today.
