#1) Who was president when queen elizabeth ii ascended to the throne
Queen Elizabeth ascended the throne at the age of 25, upon the death of her father, King George VI, on 6 February 1952, and was proclaimed queen by her various privy and executive councils shortly afterwards. The coronation took place more than a year later because of the tradition that holding such a festival is inappropriate during the period of mourning that follows the death of a monarch. At the time of her asccession to the throne Harry S. Truman was currently the 33rd President of the United States of America.
