Elizabeth didn’t want the job. Her uncle King Edward VIII should have reigned but abdicated in order to marry “the woman I love”. This meant the succession fell to her father who became King George VI. He only lasted sixteen years before dying in 1952, and this put Elizabeth on the throne at age 26.
Queen Elizabeth never forgave Edward now Duke of Windsor for causing her father’s early death.
If Wallis Simpson had not been so sexually skilled and kinky, Elizabeth’s reign may not have happened.
