I came across the idea of British Israelism recently.

I knew that the UK had a big part in Zionism and the Arabs but it seems a lot more complicated under this world view. It was a well supported view point as well. Princess Alice, daughter of Queen Victoria was head of the movement. King George IV. Queen Elisabeth II father was also a believer in this theory.
