The Queen is now the world’s oldest head of state after Zimbabwe’s Robert Mugabe resigned from his Presidential role on Tuesday afternoon.
Mugabe — who was the oldest Head of State until hissurprisee move — handed in his resignation after 37 years as president following last week’s military coup.
At 91 years old, Queen Elizabeth II has outlasted countless world leaders and heads of state, including 19 Prime Ministers and 16 US Presidents.
Queen Elizabeth also became the second longest-serving living British monarch in 2015, surpassing Queen Victoria’s 63-year reign.
In 2007, she also became the oldest monarch in British history — a record also previously claimed by her great-grandmother, Queen Victoria.
Earlier this week, Queen Elizabeth also celebrated her 70th wedding anniversary to Prince Philip, Duke of Edinburgh. She is the only British monarch to have celebrated her diamond and platinum wedding anniversaries.
