A monarchy is a form of government in which a single leader rules a given nation for life. The general term for this leader is a monarch, whose formal title is usually King, though titles including Queen, Amir, Emperor/Empress, and Sultan are also used. While a select few monarchs are democratically elected, the overwhelming majority inherit their position from a relative (usually a parent) who was the previous monarch. The term "monarchy" can refer to either a country's government ("This kingdom is ruled by a monarchy") or to the country itself ("This kingdom is a monarchy"). Monarchies were the dominant form of government from the earliest periods of recorded history clear up to the 1900s, but are increasingly uncommon today, and those that do remain have often diluted the monarch's power.
While most democratic heads of state, such as presidents and prime ministers, are elected and can only serve a limited number of years, monarchies tend to operate differently. The king (or sultan, etc.) holds their position permanently, only giving it up when they die, step down, or (in very rare instances) commit some egregious violation of their limited rules. When this happens, the role almost always passes to a son, daughter, or other relative. As such, the only way to become the monarch in most cases is to be related as closely as possible to the existing monarch and wait for them to vacate the position one way or another. Perhaps unsurprisingly, many monarchs and heirs throughout history have either died under mysterious circumstances or been murdered outright by family members next in line for the throne.
Monarchies exist in many forms. In absolute monarchies, the monarch has complete power, with no checks or balances to their authority. However, most modern monarchies are limited monarchies, in which the power of the monarch is limited by laws, a constitution, and/or a more democratic governmental body such as a parliament. Limited monarchies can be further broken down into several sub-types such as a constitutional monarchy, a mixed monarchy, or a federal monarchy. As a result of these variations, the role and power of the modern monarch varies from country to country. While a few monarchs are still the undisputed rulers of their nations, many are essentially ceremonial figureheads with little political power. For example, England's King Charles III is the Head of State and commands great wealth, prestige, and respect—however, the country is actually ruled by Parliament and its the Head of Government, the Prime Minister.
The monarchy that the majority of people are most familiar with is that of the United Kingdom. As the reigning monarch of the United Kingdom of Great Britain and Northern Ireland, Queen Elizabeth II was a prime example of a monarch. Elizabeth was born into the royal family on 21 April 1926 and assumed the throne on 6 February 1952, at the age of 25. She reigned as queen until her death on 8 September 2022 (at age 96), a total of 70 years and 214 days, which ranks as the longest reign of any British monarch and of any female head of state in the world.
Upon Elizabeth's death, the role of monarch passed down the line of succession to her eldest son, Prince Charles, the Prince of Wales, who was installed as King Charles III on 8 September, 2022. As the heir apparent to the throne, Charles was already well known throughout the world, as were his sons Prince William, Prince of Wales; and Prince Harry, Duke of Sussex; as well as Charles' late ex-wife, Princess Diana Spencer, and his current spouse, Camilla Parker Bowles. Although Elizabeth II also has three other children—Princess Anne, Princess Royal; Prince Andrew, the Duke of York; and Prince Edward, the Earl of Wessex—Charles' eldest son, Prince William, is now next in line for the throne according to the rules of succession.
Functionally speaking, the U.K. is what is known as a constitutional monarchy, which operates under the guidance of a constitution that restricts the monarch from making decisions independently. Constitutional monarchies are often combined with some type of representative democracy, such as the U.K.'s Parliament and Prime Minister, which handles the bulk of the governance.
