Crown Dependencies in the context of "Channel Islands"

The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom, and may also legislate for the Crown Dependencies and the British Overseas Territories. Since 1999, varying degree of powers have been devolved to the devolved national parliaments of Northern Ireland, Scotland, and Wales. Each devolved parliament has different devolved powers, with Scotland being the most powerful amongst the three devolved parliaments. The central UK Parliament retains the power to legislate in reserved matters, including broadcasting, defence, and currency.

It meets at the Palace of Westminster in London. Parliament possesses legislative supremacy and thereby holds ultimate power over all other political bodies in the United Kingdom and the Overseas Territories. While Parliament is bicameral, it has three parts: the sovereign, the House of Lords, and the House of Commons. The three parts acting together to legislate may be described as the King-in-Parliament. The Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation.

The United Kingdom of Great Britain and Northern Ireland, referred to as simply "Great Britain", has been represented at every modern Olympic Games. As of the 2024 Summer Olympics, it is third in the all-time Summer Olympic medal table by overall number of medals, and fourth in number of gold medals won. London hosted the Summer Olympic Games in 1908, 1948 and 2012.

Athletes from the United Kingdom compete as part of the Great Britain and Northern Ireland Olympic Team, branded "Team GB". The team is organised by the British Olympic Association, the National Olympic Committee for the UK. Team GB also represents the United Kingdom's Overseas Territories (with the exceptions of Bermuda, the British Virgin Islands, and the Cayman Islands), and the three Crown Dependencies of Guernsey, Jersey, and the Isle of Man. Athletes from Northern Ireland can choose to compete for either Great Britain or Ireland, with most choosing Ireland. The use of "Great Britain" over "United Kingdom" has faced criticism in Northern Ireland.

The House of Windsor is the current royal house of the United Kingdom and other Commonwealth realms. The house's name was inspired by the historic Windsor Castle estate. The house was founded on 17 July 1917, when King George V changed the name of the royal house from the German Saxe-Coburg and Gotha to the English Windsor due to anti-German sentiment during the First World War. There have been five British monarchs of the House of Windsor: George V, Edward VIII, George VI, Elizabeth II, and Charles III. The children and male-line descendants of Queen Elizabeth II and Prince Philip, Duke of Edinburgh, also genealogically belong to the House of Oldenburg since Philip was by birth a member of the Glücksburg branch of that house.

The monarch is head of state of fifteen sovereign states. These are the United Kingdom, Antigua and Barbuda, Australia, The Bahamas, Belize, Canada, Grenada, Jamaica, New Zealand, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands, and Tuvalu. As well as these separate monarchies, there are also three Crown Dependencies, fourteen British Overseas Territories, two associated states of New Zealand, and one territory.

The British Islands is a term within the law of the United Kingdom which refers collectively to the following four polities:

• the United Kingdom of Great Britain and Northern Ireland (which includes England, Scotland, Wales and Northern Ireland);
• the Bailiwick of Guernsey (including the jurisdictions of Alderney, Guernsey and Sark);
• the Bailiwick of Jersey;
• the Isle of Man.

These polities constitute the principal geopolitical and territorial nucleus of British sovereignty. Distinguished from the British Overseas Territories, which are remnants of the former British Empire, the British Islands represent the core legal and constitutional realm under the direct jurisdiction of The Crown and Parliament of the United Kingdom (i.e. United Kingdom proper), albeit with varying degrees of self-governance among the Crown Dependencies. A statutory definition of the term British Islands can be found in Schedule 1 of the Interpretation Act 1978.

British overseas cities on British Overseas Territories and Crown Dependencies are remaining key places of the former far-reaching British Empire, which was a vast holding of many regions, countries, protectorates and territories. A number of notable settlements within England and constituent countries of the grouping from the medieval period onwards were granted city status by British monarchs. This is a honorific title only which grants no additional civic privileges, but it could confer a sense of increased local pride, additional prestige along with international notability and recognition to an area.

Primarily from the 20th century many territories gained independence, and this caused a reduction in the number of cities remaining within the Empire. These overseas lands did not form part of the modern United Kingdom except for Ireland, and later Northern Ireland. Today, the British Overseas Territories and Crown Dependencies remain outside the UK, but the power to designate cities continues to be vested ultimately with the UK government and the present sovereign Charles III, who is also the head of state for these lands. There are (as of 2022) presently four cities in the Overseas Territories, and one on a Crown Dependency.

The Royal Navy (RN) is the naval warfare force of the United Kingdom, responsible for defending the UK, the Crown Dependencies, and the Overseas Territories from naval attack or invasion. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.

From the early 18th century until the Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority. Following World War I, it was significantly reduced in size. During the Cold War, the Royal Navy transformed into a primarily anti-submarine force, hunting for Soviet submarines and mostly active in the GIUK gap. Following the collapse of the Soviet Union, its focus returned to expeditionary operations.

The Isle of Man (Manx: Mannin [ˈmanɪnʲ], also Ellan Vannin [ˈɛlʲan ˈvanɪnʲ]), or Mann (/mæn/ man), is a self-governing British Crown Dependency in the Irish Sea, between Great Britain and Ireland. As head of state, Charles III holds the title Lord of Mann and is represented by a Lieutenant Governor. The government of the United Kingdom is responsible for the Isle of Man's military defence and represents it abroad, but the Isle of Man still has a separate international identity.

Humans have lived on the island since before 6500 BC. Gaelic cultural influence began in the 5th century AD, when Irish missionaries following the teaching of St Patrick began settling the island, and the Manx language, a branch of the Goidelic languages, emerged. In 627, King Edwin of Northumbria conquered the Isle of Man along with most of Mercia. In the 9th century, Norsemen established the thalassocratic Kingdom of the Isles, which included the Hebrides and the Northern Isles, along with the Isle of Man as the southernmost island. Magnus III, King of Norway from 1093 to 1103, reigned as King of Man and the Isles between 1099 and 1103.

The Church of England (C of E) is the established Christian church in England and the Crown Dependencies. It was the initial church of the Anglican tradition. The Church traces its history to the Christian hierarchy recorded as existing in the Roman province of Britain by the 3rd century and to the 6th-century Gregorian mission to Kent led by Augustine of Canterbury. Its members are called Anglicans.

In 1534, the Church of England renounced the authority of the Papacy under the direction of King Henry VIII pursuant to laws passed by the Parliament, beginning the English Reformation. The guiding theologian that shaped Anglican doctrine was the reforming Archbishop Thomas Cranmer, who developed the Church of England's liturgical text, the Book of Common Prayer. Papal authority was briefly restored under Mary I, before her successor Elizabeth I renewed the breach. The Elizabethan Settlement (implemented 1559–1563) concluded the English Reformation, charting a course for the English church to describe itself as a via media between two branches of Protestantism—Lutheranism and Calvinism—and later, a denomination that is both Reformed and Catholic.
