King Charles assumed the throne on Thursday evening (September 8) following the death of his mother, Her Majesty The Queen.
In what has been a tumultuous 48 hours since then, the new monarch has travelled back down to London with Camilla, The Queen Consort by his side.
He has met with the new PM Liz Truss, and was officially proclaimed King at the Accession ceremony in central London this afternoon (September 10).
Becoming King at the age of 73, it is likely that his reign will be one of the shortest ever, especially compared to Queen Elizabeth II's 70-year rule which just came to an end.
Despite this, one royal expert believes that history 'will be kind' to King Charles.
Writing in The Sun, Robert Jobson penned: "No doubt his reign will be short, maybe one of the shortest ever. As a result, his time on the throne will not be a remarkable one, in historical terms.
"That said, his contribution to the world during his entire lifetime certainly has been remarkable."
Jobson added that his legacy will be one of a 'courageous' man who is not afraid of 'taking risks'.
He revealed that during the Queen's final years, the then-Prince of Wales worked 14 hour days as he took on more state-related duties.
He took on the role of a 'Shadow King', and reportedly done 'most of the heavy lifting' when it came to royal duties.
Charles will never break constitutional rules but, for him, leadership is pre-eminent. He is not a follower., according to Jobson.
He added: "He is a good listener who takes enormous trouble to be on top of global affairs, different cultures and religion.
"But the key to his leadership qualities is summed up by a former senior member of the royal household: “He knows he has a unique ability as somebody who can convene important people who would not otherwise sit in a room together.”
"He is, if you like, the ultimate chairman of the board."
In his first heartfelt speech as King which was broadcast to the nation on Friday (September 9), King Charles said: “I speak to you today with feelings of profound sorrow.
"Throughout her life, Her Majesty The Queen – my beloved Mother – was an inspiration and example to me and to all my family, and we owe her the most heartfelt debt any family can owe to their mother; for her love, affection, guidance, understanding and example."
He continued: “Queen Elizabeth was a life well lived; a promise with destiny kept and she is mourned most deeply in her passing. That promise of lifelong service I renew to you all today.
“Alongside the personal grief that all my family are feeling, we also share with so many of you in the United Kingdom, in all the countries where The Queen was Head of State, in the Commonwealth and across the world, a deep sense of gratitude for the more than 70 years in which my Mother, as Queen, served the people of so many nations.
“In 1947, on her 21st birthday, she pledged in a broadcast from Cape Town to the Commonwealth to devote her life, whether it be short or long, to the service of her peoples.
“That was more than a promise: it was a profound personal commitment which defined her whole life. She made sacrifices for duty.
“Her dedication and devotion as Sovereign never waivered, through times of change and progress, through times of joy and celebration, and through times of sadness and loss.
“In her life of service we saw that abiding love of tradition, together with that fearless embrace of progress, which make us great as Nations. The affection, admiration and respect she inspired became the hallmark of her reign.
“And, as every member of my family can testify, she combined these qualities with warmth, humour and an unerring ability always to see the best in people.
“I pay tribute to my Mother’s memory and I honour her life of service. I know that her death brings great sadness to so many of you and I share that sense of loss, beyond measure, with you all."
Towards the end of his speech, King Charles announced that William and Kate have gained the titles of the 'Prince and Princess of Wales.
Meanwhile he also paid tribute to Prince Harry and his wife Meghan Markle, exclaiming his love for them as they build their new life overseas.
