Here is a look at the Duke of Edinburgh’s life and royal role:
– Who was the Duke of Edinburgh?
The Duke of Edinburgh – also known as Prince Philip – was married to Queen Elizabeth II.
He was the longest-serving consort in British history.
The duke was born on June 10 1921 on the Greek island of Corfu.
He was a prince of Greece and Denmark and his parents were Prince Andrew of Greece and Princess Alice of Battenberg.
He was exiled from Greece as a child and grew up in France, Germany and Britain.
They were distant cousins and both great-great-grandchildren of Queen Victoria.
They attended some of the same events in their youth – a wedding in 1934 and King George VI’s coronation in 1937.
But they had their first publicised meeting in 1939 when Philip was 18 and Princess Elizabeth was 13.
– When did they fall in love?
Elizabeth first fell for tall, blond, athletic Philip during their Dartmouth encounter when he amused her by jumping over tennis nets.
The pair wrote regular letters to one another and later met on numerous occasions, with Philip even spending Christmas with the royal family during the Second World War.
– What did Philip do in the Second World War?
He fought for Britain in the Royal Navy.
He saw active service from the Indian Ocean to the Mediterranean, and by 1945 was in Tokyo Bay as the Japanese surrendered.
– When did he marry Princess Elizabeth?
Philip and Elizabeth’s engagement was announced in July 1947 and the royal wedding took place on November 20 1947 in London’s Westminster Abbey. Elizabeth was 21 and not yet Queen.
Five years after they married – in 1952 – George VI died and Elizabeth became the monarch.
Philip renounced his Greek title and became a naturalised Briton in 1947. He became Lieutenant Philip Mountbatten.
He chose his new surname Mountbatten – an Anglicised form of his mother’s maiden name Battenberg – rather than Schleswig-Holstein-Sonderburg-Glucksburg – the family name of the Danish royal house from which his father was descended.
He was made the Duke of Edinburgh by Princess Elizabeth’s father, George VI, just before the wedding. The Queen later made him a prince of the UK.
– How did the Queen and the duke manage to stay married for so long?
They shared interests – a love of horses and outdoor life – and had the same dutiful royal training.
Philip loved carriage driving, while the Queen might go to dinner with friends.
In character, they were very different. The duke was seen as cantankerous and adventurous, while the Queen is viewed as passive, cautious and conventional.
– How many children did they have?
The Queen and Philip had four children: Prince Charles (now the Prince of Wales), Princess Anne (now the Princess Royal), Prince Andrew (now the Duke of York) and Prince Edward (now the Earl of Wessex).
He was George, Charlotte, Louis and Archie’s great-grandfather.
He was also grandfather to the Duke of Cambridge and the Duke of Sussex.
He is known for supporting the Queen through her long reign, and carrying out thousands of royal engagements.
He also was involved for decades with hundreds of charities, and set up The Duke of Edinburgh’s Award youth adventure scheme.
– What else is he known for?
His gaffes. The duke was famed for his off-the-cuff remarks, which ranged from the quick-witted and funny to the politically incorrect and offensive.
The husband of a reigning Queen, unlike a Queen consort, is not crowned nor anointed at a coronation.
