RENOWNED for her wild partying, high-profile romances and incredibly haughty remarks, Princess Margaret revolutionised what it meant to be royal.
But who exactly was Queen Elizabeth II's younger sister with a VERY colourful love life? We take a look…
Who was Princess Margaret?
HRH Princess Margaret was born on August 21, 1930, at Glamis Castle in Scotland, to King George VI and Queen Elizabeth.
She was the younger sister and only sibling of Queen Elizabeth II.
For several days the registration of the princess' birth was deliberately delayed in order to avoid her being numbered 13 and associated with its 'unlucky' connotations.
In 1936 Princess Margaret's world was turned upside down when her uncle King Edward VIII abdicated to marry divorcee, Wallis Simpson.
It meant her father, a reluctant Prince George, would become King and that her sister Elizabeth was now the country's future Queen.
At the tender age of six, Margaret was second in line to the British throne.
When she was a child, there were also unfounded rumours that she was deaf and mute.
The Princess was home-schooled alongside her sister, but as an adult Margaret was said to have been resentful about her "limited education".
To many she was boisterous and outspoken, a far cry from the sensible and reserved nature of her older sister.
Princess Margaret opted for an extravagant life.
The royal rebel reportedly struggled being in the shadow of her sister, the Queen, unable to make sense of what her own role in society was.
The Princess was regarded as a fashion icon of the 50s and 60s, with her bold dress sense being dubbed The Margaret Look.
How many children did Princess Margaret have?
In the same year Margaret gave birth to their first child David on November 3.
The couple's second child Lady Sarah was born three years later on May 1, 1964.
In 1994, she married the actor Daniel Chatto, and the couple have two children together: Samuel and Arthur.
When Princess Margaret died of a stroke in 2002, both Lady Sarah and David started a charity in her honour – the Princess Margaret Fund – which supports stroke research.
When did Princess Margaret die?
On February 9, 2002, Princess Margaret passed away, aged 71, from cardiac problems following a stroke.
By 2001 the Princess had suffered several strokes, lost sight in one eye and most of the left side of her body was paralysed.
The chain-smoker and heavy-drinker had a lung operation in 1985 and a bout of pneumonia in 1993.
Just seven weeks after her daughter's death, the Queen Mother died in her sleep at the age of 101.
Who was Princess Margaret's husband Lord Snowdon?
On May 6, 1960, Princess Margaret married English photographer and film-maker Antony Armstrong-Jones at Westminster Abbey.
The ceremony was the first Royal Wedding to be broadcast on television, attracting viewers of 300 million worldwide.
The princess first met Armstrong-Jones at a dinner party in 1958 and by October 1959 they were engaged after "Tony" proposed with a ruby engagement ring displaying diamonds in the shape of a rosebud.
The Snowdon marriage marked the age of the Swinging Sixties.
Embracing the decade of parties and flamboyant lifestyle, the newlyweds established a social circle outside of aristocracy with the likes of The Beatles and actor Jack Nicholson.
The marriage of a "commonor" and a royal was also thought to represent the breaking down of British class barriers at the time.
In 1961 Armstrong-Jones was given the titles Earl of Snowdon and Viscount Linley.
