In 1917... after his cousin Tsar Nicholas II was forced by revolutionaries to abdicate [Tsar Nicholas was murder by Bolsheviks in 1918]... British King George V changed his German name to Windsor.
In 1937 pro-German King Edward VIII abdicated the British throne to marry an American divorcee.
Now British Prince Harry will marry a half-black American divorcee raised Catholic.
There is a huge historic irony in all that mess.
