Prince Harry is the youngest son of King Charles and the late Diana, Princess of Wales.
Born Henry Charles Albert David on 15 September 1984, he is currently fifth in line to the throne after his older brother, Prince William, and his three children, Prince George, Princess Charlotte and Prince Louis.
Harry's life has been documented from the moment he made his debut on the steps of the Lindo Wing. From his first day at school and boarding at Eton College to passing his military training at Sandhurst and meeting the love of his life, Meghan Markle.
The couple were made the Duke and Duchess of Sussex on their wedding day in 2018. Less than a year later, they became parents to baby Archie.

Harry starts Eton College
Harry followed in his big brother's footsteps and passed the entrance exams for Eton College, enrolling in 1998.
In his memoir, Spare, Harry says he threw himself into sport at the Windsor-based private school.
"Sport, I decided, would be my thing at Eton," he wrote. "Sporty boys were separated into two groups: dry bobs and wet bobs. Dry bobs played cricket, football, rugby, or polo. Wet bobs rowed, sailed, or swam."
He added: "I played every dry sport, though rugby captured my heart. Beautiful game, plus a good excuse to run into stuff very hard. Rugby let me indulge my rage. I simply didn't feel pain the way other boys did, which made me scary on a pitch."

Best man

The Duke later wrote in his book, Spare: "The public had been told that I was to be best man, but that was a bare-faced lie. The public expected me to be best man, and thus the Palace saw no choice but to say that I was."
Harry claims that William chose two best men in his close-knit circle - James Meade and Thomas Van Straubenzee.

Harry completed two tours of Afghanistan as a forward air controller and an Apache helicopter pilot, in 2007 to 2008 and from 2012 to 2013. He served for ten years in the military, rising to the rank of Captain.
