• Princess Diana was a teacher before marrying Prince Charles.
• After divorcing Charles, Diana became a world famous advocate for different causes, like better treatment for AIDS and HIV patients.
• Her sons Prince William and Prince Harry remember her as a loving and "informal" mother.
Princess Diana tragically died at the age of 36 over 20 years ago, in 1997.
She was first propelled into the national spotlight at the age of 20, when she wedded Great Britain's Prince Charles at the age of 20.
Their troubled marriage ultimately imploded, turning the couple in tabloid fodder.
However, Diana went on to become an international icon in her own right. Her sophisticated style dictated fashion trends. Her dedication to charitable causes won her admiration and accolades.
And, in the wake of her death in Paris, then-UK Prime Minister Tony Blair famously referred to her as "the people's princess." The mass, global outpouring of grief that her death sparked proved it an apt observation.
Here's a look at the life of Diana, Princess of Wales:
Diana Frances Spencer was born on July 1, 1961 to a British noble family. Her brother, the Earl Spencer, reminisced that she was 'incredibly brave,' even as a young girl.
In school, the future princess failed all her O-levels — twice. However, Diana had a sense that she was destined for something important. "I knew that something profound was coming my way," she said in the documentary "Diana: In Her Own Words.""I was just treading water, waiting for it."

Before her marriage, Diana reportedly shared a flat with three roommates and worked as a part-time kindergarten teacher in London’s Pimlico district.
