Wallis Simpson and King Edward VIII
When Edward VIII fell in love with American divorcée Wallis Simpson it was an affair shocked a nation and threw Britain's monarch into a constitutional crisis. Due to strong opposition from the church and government over their marriage, Edward chose to abdicate the throne. He famously proclaimed his love for Simpson as he addressed the nation in 1936. "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," he said in his abdication speech. Choosing love over kingship, the Duke of Windsor spent most of his life outside the royal family as the couple married and settled in France. Note: Years later it was revealed in previously hidden German Documents that not only did Simpson and the Duke of Windsor have Nazi associations, but there were also plans for the Germans to re-install him as King after they invaded the U.K.
