Edward,Duke of Windsor had a history of being involved with many married women before Wallis. Rumored to be a Nazi sympathizer. During World War II he served as Governor of the Bahamas, where he was plagued by rumours and accusations that he was pro-Nazi. He reputedly told an acquaintance, "After the war is over and Hitler will crush the Americans... we'll take over... They [the Commonwealth] don't want me as their king, but I'll soon be back as their leader." He told a journalist that "it would be a tragic thing for the world if Hitler was overthrown."

Synastry.

Edward's Eris
quincunx Wallis' Moon - '07
trine Wallis' Uranus - '06

(I strongly recommend using only 30 minutes of arc for Eris in synastry....with slightly smaller orbs for trines like 20 minutes of arc...sextiles 10 or 15....quincunxes,semisextiles,semisquares,sesquiquadrates less than 10 minutes)

In this case, there are strong Eris aspects because their Eris' conjunct and Wallis has Eris aspects.....so its more like they are connected on collective level with their relationship having profound effect on many

King Edward signed the Instrument of Abdication on December 10, 1936,and announced his abdication the next day on December 11, 1936
