As Queen Elizabeth's Platinum Jubilee - marking 70 incredible years of service - is quickly approaching, it is only right that we take a look back on her extraordinary life.
The Queen said in her Jubilee message to the public: 'As I look ahead with a sense of hope and optimism to the year of my Platinum Jubilee, I am reminded of how much we can be thankful for. These last seven decades have seen extraordinary progress socially, technologically and culturally that have benefitted us all; and I am confident that the future will offer similar opportunities to us and especially to the younger generations in the United Kingdom and throughout the Commonwealth.
'As I look forward to continuing to serve you with all my heart, I hope this Jubilee will bring together families and friends, neighbours and communities – after some difficult times for so many of us – in order to enjoy the celebrations and to reflect on the positive developments in our day-to-day lives that have so happily coincided with my reign.'
Elizabeth II was never meant to be Queen. When she was born on 21 April 1926, she was unlikely to ever rule, as her father was the second son of the monarch. However, when Edward VIII abdicated the throne and her father became King, Princess Elizabeth became the heir presumptive to the British throne.
Whilst on a royal trip to Kenya, King George VI died of lung cancer at 56-years-old on 6 February 1952. At just 25-years-old, the then Princess Elizabeth, took on the huge responsibility of leading the monarchy. Her formal coronation as Queen Elizabeth II took place on 2 June 1953, in Westminster Abbey.
Here we take a look back at the life of the young Queen Elizabeth...
