The United Kingdom’s Queen Elizabeth II, 89, became the longest-reigning British monarch on Wednesday. As 40th monarch since 1066, she surpassed her great-great grandmother Queen Victoria for the longest run in the country’s history — just over 63 years and six months.

Queen Elizabeth asked there be no fuss over the milestone. But Brits will celebrate quietly by raising a glass to Her Majesty and remembering key moments since her ascension.

Take a look at the pivotal moments of Elizabeth’s reign.

This picture was taken when she was still Princess Elizabeth, the heir to the throne.


At 25, Princess Elizabeth ascended the throne. She was married and the mother of two when her father King George VI died on Feb. 6. She was in Kenya on holiday. Two days later, she arrived home as Queen to meet a line of somber ministers.


Her coronation took place more than a year later on June 2 in Westminster Abbey. It was the first major international event broadcast on TV. She stands here on the Buckingham Palace balcony with her husband Prince Philip, Duke of Edinburgh.


In October, her sister Princess Margaret — under pressure from the church and a threat to her status as a royal princess — declared she would not marry her love Group Capt. Peter Townsend. Queen Elizabeth wished her sister happiness, but her government was against a marriage to Townsend, a divorced man. It caused tension between the sisters. Here, the couple are seen in 1947 during a royal tour of South Africa.


It was the wedding everyone waited for — the marriage of Elizabeth’s son Prince Charles to Lady Diana Spencer in St Paul’s Cathedral on July 29. A year later on June 21, 1982, Prince William was born. He was the new heir to the British throne. Prince Harry was born on Sept. 15, 1984.


The queen was devastated by the fire at Windsor Castle in November. Afterwards she toured the damaged more than 900-year-old fortress with firemen. The fire threatened historic works of art, most of which were saved by a brigade of castle workers.


Charles and Diana announced their divorce, not the first of Elizabeth’s children. In this photo she arrives for the annual Royal Variety Performance in London. Criticism plagued her house from the fire and divorces.


Prince Harry, Prince William, Prince Charles and the queen mourned the death of Princess Diana, who died in a car crash in Paris. Under tremendous pressure from the public and the press to show more feeling publicly about the tragedy, the royal family returned to London for her funeral. The queen and Prince Philip view the sea of floral tributes to Diana at Buckingham Palace.

Prince William married Kate Middleton — now Catherine Duchess of Cambridge. In this photo, they say goodbye to queen as they leave Westminster Abbey. They’re accompanied by his best man Prince Harry and her maid of honor, sister Pippa Middleton, after the wedding on April 29.


In June, the family gathered on the balcony for the Trooping the Color parade. This photo shows the queen with her son Prince Charles, her grandson Prince William and her great-grandson George. It’s captures a rare four-generation photos of royal heirs. George’s sister Princess Charlotte was later born in May.
