NEW: The queen is honored with a 41-gun salute in London

She thanks the public for their "wonderful support and encouragement"

Celebrations of her Diamond Jubilee will continue through June

Elizabeth became queen in 1952 on the death of her father George VI

London CNN  — 

Sixty years ago Monday, a 25-year-old woman visiting a remote part of Kenya got a message that her father had died.

She cut her trip short and flew home to London. Prime Minister Winston Churchill met her at the airport – because with her father dead, she had become Queen Elizabeth II.

Celebrations of her Diamond Jubilee, marking six decades on the throne, officially begin Monday and continue through June, when London will mark the anniversary of her coronation with festivities including up to 1,000 boats sailing up the River Thames.

On Monday, the queen thanked the public “for the wonderful support and encouragement that you have given to me and (husband) Prince Philip over these years.”

She said in the open letter that she planned to “dedicate myself anew to your service.”

She called on people to “give thanks for the great advances that have been made since 1952 and to look forward to the future with clear head and warm heart” in a brief letter that she signed simply “Elizabeth R.”

She was honored with a 41-gun salute in London’s Hyde Park Monday, and a 21-gun salute in Edinburgh, Scotland.

Two new photographs of the queen were released Monday as part of the Diamond Jubilee celebrations, showing her wearing a necklace worn by Queen Victoria in her own Diamond Jubilee portrait in 1897.

She is the oldest British monarch in history, but has not yet passed her great-great-grandmother Victoria as the longest-reigning one.

Elizabeth II was not in line to the throne when she was born April 21, 1926. But the fate of Lilibet, as she was known to her friends, changed when her uncle Edward abdicated the thone to marry Wallis Simpson, an American divorcee.

That made Elizabeth’s stuttering father George king, and Elizabeth became queen when he died aged 56 following a lung operation.

The queen seems to have inherited her mother’s longevity. Queen Elizabeth the Queen Mother, as she was known once George VI died, lived to be 101.

The British monarch has no political power but Elizabeth has immense power as a figurehead. She is officially the head of state of 16 countries that used to be part of the British Empire, has met presidents and prime ministers, and has seen the world change beyond recognition during her reign.

Following the queen’s visit to Ireland in 2011 – the first by a British monarch since Irish independence – Prime Minister David Cameron described the effect Elizabeth is able to have when she chooses.

At a state banquet, “suddenly she started speaking in Irish, in Gaelic,” Cameron recalled. “It came as a complete surprise to everybody including the president (of Ireland,) who looked around the room and mouthed the word ‘Wow.’ It was that kind of moment. You don’t often get people at state banquets saying ‘Wow,’ but it was a wow moment.”
