Living in Kensington Palace until her death in 1997, Princess Diana had a cleaner, cook, dresser and her butler Paul Burrell.
She would only have police protection when attending large public events, but in her day to day life she refused to have security guards.
It comes after Diana had a turbulent time while she was a member of the royal family.
Royal biographer Penny Junor wrote: "[Princess Diana] was just bitterly unhappy, she was disappointed in her marriage as was Charles it was a car crash from the very beginning.
"When Charles and Diana got together it seemed on paper that this was the most perfect match, but Diana's childhood had been very difficult and the happy jolly-go-lucky venire that she presented to the world was nothing more than a venire.
"Charles was a very complex character and the two of them was about the worst match you could possibly have made."
Princess Diana's unhappiness as a member of the royal family may have been a contributing factor to Prince Harry stepping down and moving to America for a new life.
Harry has shared his own trials and tribulations with the media attention that comes from being a senior royal.
In an interview with ITV last year, the duke said of Princess Diana's death: "[It's] a wound that still festers"
Before going on to say: "I think (of) being part of this family, in this role, in this job every single time I see a camera, every single time I hear a click, every single time I see a flash,
"It takes me straight back, so in that respect, it's the worst reminder of her life as opposed to the best."
It comes as Donald Trump has said he won't pay for Meghan and Harry's US security. after they also stepped away from the Royal Family to seek a quieter life away from the intense public glare.
"I am a great friend and admirer of the Queen & the United Kingdom. It was reported that Harry and Meghan, who left the Kingdom, would reside permanently in Canada. Now they have left Canada for the U.S. however, the U.S. will not pay for their security protection. They must pay!" Trump tweeted.
After Trump proclaimed that he would not be providing secret services agents to the former royal couple, the Sussexes spokesperson quickly hit back.
"The Duke and Duchess of Sussex have no plans to ask the U.S. government for security resources," a spokesperson for Meghan and Harry told Fox News.
"Privately funded security arrangements have been made."
Meghan and Harry later confirmed their security will be paid for by them, but Twitters users still weighed in.
One said: "What nerve, they leave Canada who told them no more security and now they're here begging? Too bad."
Another replied: "Not working members of the Royal Family ONLY CELEBRITIES! Does the US have to pick up their SECURITY COSTS?"
A third commented: "So Britain will be footing the full security bill, right? It's ludicrous to think America should help with their security - Prince Harry is nothing to us. Harry does understand this, right? Harry understands Donald Trump is still OUR President, right?"
Prince Charles and Princess Diana married back in 1981, however, their happy union was not to be, after rumours of an affair between Charles and Camilla swirled. In 1992 the pair separated and divorced in 1996 after their split Diana no longer wanted to carry on needing a security team.
Much like her son Harry and his wife Meghan Markle, Diana sought to live a more private and quiet life after her whirlwind royal romance ended.
"Over the next few months, I will be seeking a more suitable way of combining a meaningful public role with, hopefully, a more private life," she said in 1993 at a benefit lunch for the Headway National Injuries Association.
The Sussexes currently have a reported 15 person security team, however, Diana was desperate to have freedom and therefore she kept her staff force small.
