On Friday, Queen Elizabeth II celebrates her 91st birthday.
In her 91 years, the record-breaking monarch has pretty much seen it all — she has undertaken more than 260 official overseas visits and has lived through 20 British prime ministers and 15 US presidents.
This year's celebrations are expected to be a low-key affair including the traditional gun salute at Tower Bridge and Hyde Park.
Last year's celebrations were a much more elaborate, with 1,000 beacons being lit and street parties being held across the country to mark her 90th.
In celebration of her 91st birthday, we've found a photo from every single year of her remarkable life.
1926: The Queen was born at 2:40 a.m. on April 21, 1926, at 17 Bruton Street in London. This photo shows the newly-born Princess Elizabeth with her father and mother, the Duke and Duchess of York — later King George VI and Queen Elizabeth.
1927: She was the couple's first child and was christened Elizabeth Alexandra Mary in Buckingham Palace's private chapel. She was named Elizabeth after her mother, Mary after her grandmother Queen Mary, and Alexandra after her great-grandmother Queen Alexandra.
1928: No one ever thought Elizabeth would become queen. This only became apparent once her father's elder brother Edward abdicated, putting her father on the throne, and making her first-in-line.
