Queen Elizabeth II’s Sapphire Jubilee, by the numbers

LONDON – On Monday, Queen Elizabeth II marks her Sapphire Jubilee, becoming the first British monarch to reign for 65 years. It’s just one of many milestones the queen has marked in her nine decades. Here’s are some other significant numbers about her record-breaking life and reign:

Elizabeth assumed the throne on the death of her father, King George VI, on Feb. 6, 1952. On September 9, 2015, she became Britain’s longest-reigning monarch, passing her great-great-grandmother, Queen Victoria.

She turned 90 on April 21, 2016, and has been the world’s oldest monarch since the death of Saudi Arabia’s King Abdullah in 2015.
