In Pictures: Queen Elizabeth's 70 years in throne

 Elizabeth Alexandra Mary Windsor wasn’t born to wear the crown. But destiny intervened.

The woman who became Queen Elizabeth II will mark 70 years on the throne Sunday, an unprecedented reign that has made her a symbol of stability as the United Kingdom navigated an age of uncertainty.

From her early days as a glamorous young royal in glittering tiaras to her more recent incarnation as the nation’s grandmother, the queen has witnessed the end of the British Empire, the advent of multiculturalism, the rise of international terrorism, and the challenges posed by Brexit and the COVID-19 pandemic. In a world of relentless change, she has been a constant — representing the UK’s interests abroad, applauding the nation’s successes and commiserating in its failures, and always remaining above the fray of politics.

That constancy should earn Elizabeth a royal epithet like those of her predecessors such as William the Conqueror, Edward the Confessor and Alfred the Great, said royal historian Hugo Vickers.

“I’ve always thought she should be called Elizabeth the Steadfast,” Vickers told The Associated Press. “I think it’s a perfect way of describing her. She wasn’t necessarily expecting to be queen, and she embraced that duty.”

As the elder daughter of King George V’s second son, Elizabeth, now 95, was expected to live the life of a minor royal when she was born on April 21, 1926. Dogs and horses, a country house, a suitable match — a comfortable but uneventful life — seemed her future.

But everything changed a decade later when her uncle, King Edward VIII, abdicated so he could marry the American divorcee Wallis Simpson. Elizabeth’s father became King George VI, making the young princess heir apparent.
