Britain’s Queen Elizabeth II turns 95 today, just days after burying her late husband Prince Philip, in what will be her first birthday alone in more than seven decades.

The Queen was born on 21 April 1926 at 17 Bruton Street in Mayfair, London. She was the first child of The Duke and Duchess of York, who later became King George VI and Queen Elizabeth.

This year she remains at Windsor Castle, during a period of Royal Mourning following the death of her husband. Prince Philip, whom Elizabeth married in 1947, died on April 9 at the age of 99.

She ascended to the throne in 1952 at the age of 25, and surpassed her great-great-grandmother Queen Victoria as Britain’s longest-reigning monarch in September, 2015. She is also queen of 15 former British colonies including Canada, Australia and New Zealand.

Elizabeth was born on 21 April 1926 in London, the first child of Albert, Duke of York, and his wife, formerly Lady Elizabeth Bowes-Lyon.
