When Princess Elizabeth was born, she was not expected to become Queen.
Her father was the second son of King George V, so she was expected to live the life of a minor royal.
But when her uncle unexpectedly left the throne, he paved the way for her to become the longest-serving monarch in UK history.
With no male siblings, the stage was set for Elizabeth to one day assume the crown.
Unlike most royal children of the time, Elizabeth was not born in a palace or castle.
She was born in a house in Mayfair, which is now a Cantonese restaurant, and was nicknamed Lilibet.
When she was born, her parents were the Duke and Duchess of York, but ten years later they became King and Queen.
Grandfather England was what Elizabeth and her younger sister Margaret called their grandfather, King George V.
They first appeared on the balcony of Buckingham Palace with their grandparents.
Already at a young age, he greeted the public with his famous royal greeting.
Elizabeth’s father unexpectedly became king when her brother abdicated to marry an American divorcee.
So she had to be educated at home and learn subjects like constitutional history.
Even though she was a princess, she didn’t have many friends the same age. Therefore, a guide company was created in the palace.
During the Second World War, Elizabeth gave her first public address to the children of the Commonwealth.
Elizabeth and her younger sister Margaret hoped to reach the many children who were living away from home because of the war.
“When peace returns, remember that it will be up to us, the children of today, to make the world of tomorrow a better and happier place.”
Elizabeth joined the Women’s Auxiliary Territorial Service during the war and was known as Second Subaltern Elizabeth Windsor.
She learned to be a driver and drove a military truck.
Princess was sometimes referred to as 230873 during her service.
Elizabeth married Lieutenant Philip Mountbatten two years after the war.
The princess had to collect tickets to buy a dress, like all other brides in Britain at the time.
Unlike others, her wedding ceremony was broadcast to 200 million people worldwide.
Prince Charles was born in 1948.
Elizabeth and Philip had three more children, Princess Anne, Prince Andrew and Prince Edward.
Their family will continue to grow, with eight grandchildren and 12 great-grandchildren.
When her father died in 1952, Elizabeth became Queen Elizabeth II.
A year later she was crowned in Westminster Abbey and broadcast the Commonwealth Address.
“During my life and with all my heart I will try to be worthy of your trust,” she said.
