Princess Elizabeth was born at 2.40am on April 21, 1926, at 17 Bruton Street in Mayfair, London. As George Vโs first grand-daughter, she was said to have charmed the notoriously cantankerous King with her winning smile, blonde curls and determinedly sunny disposition.
The young princess was third in line to the throne and it was never expected that Elizabeth or โLilibetโ as she called herself would be Queen, so her childhood, while in the public eye, was relatively carefree.
Yet it was nevertheless a very royal upbringing, with Elizabeth raised by nannies and governesses, while her parents โ Elizabeth Bowes-Lyon and Prince Albert (โBertieโ) York โ were busy with official duties.
In 1930, Elizabethโs sister, Margaret, was born and the two princesses became inseparable under the tutelage of governess Marion Crawford or โCrawfieโ as she was known to the girls. In London, the family lived at 145 Piccadilly and adopted the Royal Lodge in Windsor Great Park as their country retreat.
There, Elizabeth fell in love with the familyโs first corgi, Dookie, and with the great outdoors and horse riding. Yet all that was about to change.
In 1936, Princess Elizabethโs uncle, King Edward VIII, abdicated after just 325 days on the throne, choosing โthe woman I loveโ, American divorcee Wallis Simpson, over public office. His brother, Bertie, was thrust into the spotlight and crowned King George VI, with his family relocating to Buckingham Palace.
Princess Margaret reportedly asked her sister, โDoes this mean youโre going to become Queen?โ, with Elizabeth calmly responding, โYes, I suppose it doesโ.
Behind the scenes, though, there was much work to be done. Suddenly, Elizabeth needed to be groomed for the highest office in the land, so her education was stepped up a notch to include matters of state. Her natural diligence and innate sense of duty meant she rose to the occasion. With their sights on rebuilding a strong monarchy, the royal family united and the King was often heard referring to them as โwe fourโ.
During World War II, the teenage princesses were evacuated to Windsor Castle and, in 1945, joined the Womenโs Auxiliary Territorial Service, where Elizabeth worked as a mechanic and driver to help the war effort.
As the most eligible young woman in Britain, Elizabeth started to attend society balls and, despite the heavy weight of expectation on her shoulders, she shone. There was no doubt this was a Queen in the making.
Itโs hardly possible to believe that at just 25 years of age, Queen Elizabeth embarked on a journey that would see her crowned as Englandโs longest reigning monarch.

Elizabeth, the Duchess of York, looks lovingly into the face of her one-month-old baby, her first-born child, the future Queen Elizabeth II. Elizabeth was christened in Buckingham Palace with water from the River Jordan. Like most babies, she reportedly cried throughout the ceremony.

โElizabeth had a warmer upbringing than many of the children of the great aristocratic dynasties of inter-war Britain,โ says royal biographer Andrew Marr. โHers was a close, physically a ectionate family.โ
