How a single afternoon transformed the British monarchy

Health · Published 18 October 2026 Swipe more like this →

In short: On 10 September 2022, a formal ceremony at St James's Palace officially announced the reign of King Charles III. While the transition of power is instantaneous upon a monarch's death, the global rollout of this proclamation involved a complex, synchronized dance of heralds, gun salutes, and local traditions.

The legal transition of the throne occurs the moment the previous monarch passes away, as seen with the death of Queen Elizabeth II on 8 September 2022. However, the formal proclamation of Charles III took place at 10:00 BST on 10 September 2022. During the Accession Council at St James's Palace, the Lord President of the Council read the proclamation, which officially introduced the new regnal name. Although 700 members of the Privy Council were eligible, space limitations meant only 200 were summoned to attend.

The announcement was not limited to London; it was a global event. While the UK Parliament suspended activities for 10 days, the proclamation was cascaded through various territories. During the Rideau Hall ceremony, a period of silence was observed, yet the Royal Canadian Artillery's 21-gun salute went off prematurely, preceding the reading of the French text. In the overseas territories, the reach was vast: from video links to the British Antarctic Territory to ceremonies in Bermuda, the Cayman Islands, and Gibraltar.

Local customs added unique layers to the event. In Wales, the proclamation was read in both English and Welsh at Cardiff Castle. In Scotland, the ceremony at Mercat Cross was met with some protests. Even in the smallest territories, like the Pitcairary Islands, the news was delivered via video link from New Zealand. This coordinated effort ensured that while the line of succession remains identical across the 14 other Commonwealth realms, the local expression of the new King's reign was uniquely personal to each community.
