When Lady Diana Spencer married to the Royal family in 1981 on May 7 (the same month she turned 20), she quickly became the star of the show. Her beauty, her style, her shyness, her warmth, her humor, her presence captivated the world — soon the Princess of Wales made the most famous woman in the world and, unfortunately, it was the point of controversy between Diana and her husband, Prince Charles, that Diana hated to be in the limelight from him.

However, Diana "wasn't aware of the royal machinery" before marrying Charles (of course, now King Charles), Miller reports. Diana, when she got engaged to Charles in 1981, was only 2 years old and had no idea what she was obsessed with and consenting to, her friend said. "The pair married in a lavish ceremony at St. Paul's Cathedral in 1981 - and it looked like a fairy-tale romance in public, but behind closed doors Diana struggled," Miller wrote. The couple's marriage eventually broke down acrimoniously, with many of their problems playing out on the front page of the newspaper."

One of the most important sources of tension was Diana's massive popularity, Miller added, "In the early days of their union, Charles would often be overshadowed by his beautiful wife, cheering for the princess and shouting her name and desperate to get a glimpse or short conversation with her on behalf of the future king." He added.

During a controversial panorama interview on the BBC in 1995, Diana herself confirmed as well, "The pressure on both of us as a couple with the media was phenomenal and was misunderstood by many. We would go around Australia, for example, and all you can hear, oh, she is on the other side."Well, if you are a man like my husband, if you are a proud man, if you listen to it every day for 4 weeks, you care about it. And you feel low about it instead of feeling happy and sharing it.(Charles and Diana made a tour of Australia and New Zealand together in 1983-3 and 4 months and brought the baby Prince William, who was just nine months old.Claiming that the attention pointed to her caused "a lot of jealousy," Diana said, "so many complex situations arose.""

Diana's friend James Corthurst—Diana had known Diana from her teenage years until her death in 1997 - not only did Diana not know what she was doing when it came to the royal machinery that works to keep the institution of the monarchy going, but the company claimed she did not know what to do with the quality of her star, either. (Colthurst is probably best known for the context to serve as a go-between when Diana secretly collaborated with journalist Andrew Morton on his bombshell 1992 book Diana: Her true Story. "Colthurst, a mutual friend of both parties, interviewed on behalf of Morton and recorded a few hours' worth of tapes of Diana answering the author's questions, which would eventually become a book," Miller reports.

"Her engagement and marriage to Prince Charles brought her worldwide fame," Colthurst said, Per The Telegraph. "But I felt that when she joined the royal family, she might not have been fully aware of the machine she was in. The company, for its part, was not used to having a superstar in its midst, and I don't think it knew how to deal with the sheer amount of publicity she generated.

Corthurst said, "She wasn't given a lot of easy stuff at Clarence House at the wedding build-up, and no one was about to happen."She didn't have a big support team at the palace. She was just trying to do her best. When she did what she thought was right, it was well received by the public, but not necessarily by the company.

After 11 years of marriage and two children, Charles and Diana separated in 1992 and eventually divorced in August28, 1996.
