Catherine has been compared to her late mother-in-law, Princess Diana, ever since joining the royal family, with royal commentators often highlighting similarities between the two women.
Royal expert Christopher Andersen believes the "Catherine era" began when she married Prince William in 2011, arguing that few modern royals have had a greater impact on the monarchy.
Speaking to Fox News Digital, Andersen said Catherine was already making a significant contribution to the royal family before her cancer diagnosis in 2024 temporarily interrupted her public duties.
He noted that comparisons with Diana were unavoidable because both women are widely admired for their charisma, compassion, style and ability to connect with people on a personal level.
However, Andersen argued that Catherine possesses one important advantage that Diana did not have: a husband who genuinely loves and supports her.
The expert also pointed to the differences in their upbringing, suggesting that Diana's difficult childhood left lasting emotional challenges, while Catherine benefited from a stable family environment. He added that the Princess of Wales is now working to provide her own children with a similarly grounded upbringing.
Meanwhile, royal commentator Ailsa Anderson recently praised Catherine's role as the monarchy's future Queen. Speaking to People magazine, she described her as glamorous, warm and approachable, adding that public visibility remains an essential part of royal life.
As Catherine continues to carry out her royal responsibilities, experts believe her popularity and influence will remain central to the future of the monarchy.
