One year has passed since the death of Queen Elizabeth — Britain’s longest reigning monarch — and her son King Charles took the throne.

After the longest tenure as Prince of Wales, Charles has spent most of his life preparing for the day when he would take over as sovereign and symbolic head of state.

His first year as monarch has had its ups and downs: with an increasing number of republican protests and internal family dramas marring his record, amongst the global attention of set piece events like the Coronation and Trooping the Colour.

Charles has spent the anniversary of his mother’s death attending a church service at Crathie Kirk, alongside some other members of the Royal Family. His sons honoured their grandmother separately: with Prince Harry spotted visiting her resting place in St. George's Chapel, Windsor, solo earlier today and the Prince and Princess of Wales visiting St. David's Cathedral for a "moment of reflection".

Yahoo News UK breaks down some of the most significant moments of the first year of Charles's reign.

The Windsor family saga has rolled on in the last year, with explosive allegations from the Sussexes that other royal households leaked negative stories about the couple in return for better press for themselves.

Harry & Meghan, the Netflix series, provided a deep dive for their fans into their exit from royal life, although much of what was included had been previously touched on before in their bombshell 2021 interview with Oprah Winfrey.

What came next in Harry's bestselling memoir Spare would perhaps have been more of a challenge for the new King, as his youngest son drew back the veil on the monarch's parenting approach, and accused Prince William of physically attacking his younger brother.

Whilst promoting his memoir in January, Harry made it clear that his relationship with his brother and father had yet to improve. However, Harry was in attendance at the coronation, showing a public display of support to his father, despite having no official role in the ceremony, unlike Prince William and his eldest son Prince George.

Charles's most recent polling numbers paint a mixed picture with William, Kate and Anne all ranking higher in popularity than the King himself — an issue the late Queen Elizabeth did not have to face.

The King's approval most recently came in at 60%, while William enjoys 74%, Kate 73% and Anne 72%

It was recently reported that Harry and Meghan, despite coming in some of the lowest approval ratings at 31% and 24% respectively, are the most "high value" royals, with coverage of them bringing in an estimated value of £1,182,440 in the last three months.

Despite their lack of popularity at this stage, one thing is certain: people are paying attention to the Sussexes with the working royals under Charles's leadership failing to hit the same level of interest, even if they are more well thought of by the public.

Six out of ten Britons support the monarchy continuing, but in the under 25s only 37% think the system should continue, and the last poll before her death had an 82% approval rating for the late Queen.

Approval across the Commonwealth states that hold Charles as their head of state is also waning: with Australia declining to put his image on their $5 notes, which the Queen had been featured on since 1992.

In countries in the Caribbean like Jamaica and Grenada republicanism is gaining momentum — though this issue for the Windsors was already in motion while the late Queen was alive.

Charles has also faced increasing protest domestically: attempted eggings and chants of 'Not my King' have followed him as he goes about his official engagements. The arrest of peaceful protesters at his coronation in May marred a day that would otherwise may have been remembered simply for its ornate ritual and pageantry.

As the King settles into his tenure as monarch, it remains to be seen what he will make of this mixed bag of circumstance, and whether he will be able to successfully steer the monarchy back into relevancy.
