Queen Elizabeth II

Elizabeth Alexandra Mary was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death in 2022. Her reign of 70 years and 214 days is the longest of any British monarch and the longest recorded of any female head of state in history. When conversing with Elizabeth, the correct etiquette was to address her initially as Your Majesty and thereafter as Ma'am (pronounced /mæm/), with a short 'a' as in jam.
