Queen Elizabeth & Prince Philip's Relationship Timeline Is Legendary

Queen Elizabeth II doesn't just boast the title of current longest-ruling monarch (having been the queen for nearly 70 years) — she also boasts the longest marriage of any British sovereign. She and Prince Philip, Duke of Edinburgh, were married for over 73 years, surpassing the marriage of former record holders, King George III and Queen Charlotte, by well over a decade. And believe it or not, Queen Elizabeth and Prince Philip's relationship timeline actually began long before their wedding day. Their love story was truly epic, which makes Philip's recent passing all the more tragic.

On April 9, 2021, the Palace confirmed Prince Philip's death at the age of 99. The longest-serving royal consort in history left behind four children, eight grandchildren, 10 great-grandchildren, and — of course — his devoted wife, whom he first met when he was just 13 years old. Though the two reportedly had their ups and downs over the years (because what else would you expect from two people who spent more than eight decades together?), their partnership will certainly go down in royal history. Here are just some of the highlights from their legendary relationship, which first began all the way back in 1939.

They Met In July 1939

Philip and the Queen had a few royal run-ins before their official introduction to each other. When Prince Philip was 13 and Princess Elizabeth was eight, they both attended the November 1934 wedding of the future Duke and Duchess of Kent: Elizabeth's uncle, Prince George, and Philip's cousin, Princess Marina. Then, three years later, they were both guests at the coronation of King George VI.

However, it wasn't until July of 1939 that the two had their first publicized meeting at the Royal Naval College in Dartmouth, Devon. Then-18-year-old Philip was introduced to Elizabeth — who was just 13 at the time — at the house of the Captain of the College. According to a two-page letter Elizabeth wrote to author Betty Shew, the princess was smitten with the young naval cadet from the very beginning.

Soon after, Philip left to serve in the British Royal Navy, and he and Elizabeth became pen pals, exchanging letters in his absence.

After a seven-year-long courtship, the future Queen and Duke were secretly engaged in 1946, though the official announcement wasn't made until July 1947, after Elizabeth had turned 21 years old (at her father's insistence). In order to marry Elizabeth, Philip was forced relinquish his existing Greek and Danish princely titles and become a British citizen.

The couple wed later that year in a relatively low-key affair due to wartime austerity. On Nov. 20, 1947, they tied the knot at Westminster Abbey in London, and the ceremony was followed by a reception at Buckingham Palace.

Tragedy struck on Feb. 6, 1952, when Elizabeth's father, King George VI, passed away due to a coronary thrombosis. At the time, Elizabeth and Philip were in Kenya ahead of their tour of Australia and New Zealand, and at the age of 25, Elizabeth became the Queen of England.

On June 2, 1953, the Queen was coronated, and the new title reportedly put a strain on her relationship with Philip, especially since he was forced to give up his career in the Royal Navy to take on a subordinate role. As he explained to The Independent in 1992, "I thought I was going to have a career in the Navy, but it became obvious there was no hope. There was no choice. It just happened. You have to make compromises. That's life. I accept it. I tried to make the best of it."

Though Philip was given the title of Duke of Edinburgh when he first married Elizabeth, she later made Philip a prince in a February 1957 coronation. "The Queen has been pleased to declare her will and pleasure that His Royal Highness the Duke of Edinburgh shall henceforth be known as His Royal Highness The Prince Philip, Duke of Edinburgh," the palace said in a statement on Feb. 22, 1957, allowing him to reclaim the title he'd been forced to renounce nearly a decade earlier.

Twenty-five years later, Philip delivered a speech in honor of his golden wedding anniversary with the Queen. "The main lesson that we have learned is that tolerance is the one essential ingredient of any happy marriage," he said. "It may not be quite so important when things are going well, but it is absolutely vital when the going gets difficult. You can take it from that the Queen has the quality of tolerance in abundance."

During her golden jubilee speech, which marked 50 years of being Queen, Elizabeth gave a speech in which she praised her husband's support.

"The Duke of Edinburgh has made an invaluable contribution to my life over these past 50 years, as he has to so many charities and organizations with which he has been involved."
