Death and state funeral of Elizabeth II in the context of "Balmoral Castle"

The monarchy of the United Kingdom, commonly referred to as the British monarchy, is the form of government used by the United Kingdom by which a hereditary monarch reigns as the head of state, with their powers regulated by the British constitution. The term may also refer to the role of the royal family within the UK's broader political structure. The monarch since 8 September 2022 is King Charles III, who ascended the throne on the death of Queen Elizabeth II, his mother.

The monarch and their immediate family undertake various official, ceremonial, diplomatic and representational duties. Although formally the monarch has authority over the government—which is known as "His/Her Majesty's Government"—this power may only be used according to laws enacted in Parliament and within constraints of convention and precedent. In practice the monarch's role, including that of Head of the Armed Forces, is limited to functions such as bestowing honours and appointing the prime minister, which are performed in a non-partisan manner. The UK Government has called the monarchy "a unique soft power and diplomatic asset". The Crown also occupies a unique cultural role, serving as an unofficial brand ambassador for British interests and values abroad, increasing tourism at home, and promoting charities throughout civil society.

The coronation of Charles III and his wife, Camilla, as king and queen of the United Kingdom and the 14 other Commonwealth realms, took place on Saturday, 6 May 2023 at Westminster Abbey. Charles acceded to the throne on 8 September 2022 upon the death of his mother, Elizabeth II.

The ceremony was structured around an Anglican service of Holy Communion. It included the King taking an oath, being anointed with holy oil, and receiving the coronation regalia, emphasising his spiritual role and secular responsibilities. Representatives of the Church of England and the British royal family declared their allegiance to him, and people throughout the Commonwealth realms were invited to do so. The Queen was crowned in a shorter and simpler ceremony. After the service, members of the royal family travelled to Buckingham Palace in a state procession and appeared on the palace's rear and front balconies. The service was altered from past British coronations to represent the multiple faiths, cultures, and communities of the United Kingdom, and was shorter than Elizabeth II's coronation. It had a peak UK television audience of 20.4 million, making it the most watched television broadcast of 2023, and attracted a global audience of 2 billion people across 125 countries.

Elizabeth II (Elizabeth Alexandra Mary; 21 April 1926 – 8 September 2022) was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death in 2022. She was queen regnant of 32 sovereign states during her lifetime and was the monarch of 15 realms at her death. Her reign of 70 years and 214 days is the longest of any British monarch, the second-longest of any sovereign state, and the longest of any queen regnant in history.

Elizabeth was born in Mayfair, London, during the reign of her paternal grandfather, King George V. She was the first child of the Duke and Duchess of York (later King George VI and Queen Elizabeth the Queen Mother). Her father acceded to the throne in 1936 upon the abdication of his brother Edward VIII, making the ten-year-old Princess Elizabeth the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In November 1947, she married Philip Mountbatten, a former prince of Greece and Denmark. Their marriage lasted 73 years until his death in 2021. They had four children: Charles, Anne, Andrew, and Edward.
