大不列顛暨北愛爾蘭聯合王國

國際簡稱UK，領土包含大不列顛島、北愛爾蘭和一些海外領地。由四個構成國組成，包含英格蘭、蘇格蘭、威爾斯和北愛爾蘭。構成國有一定自治權，英國政府則負責國防和外交事務。為全球第五大經濟體（以國內生產毛額計算），人均GDP排名全球第21名。歷經數年談判，於2021年正式脫歐，但仍是G7、北約等國際組織重要成員，也是聯合國常任理事國。目前國內有蘇格蘭獨立問題，外交上則有北愛爾蘭和愛爾蘭的邊界爭議。 Year Founded: 1801 (the year the Acts of Union went into effect) Commonly known as the UK, its territory includes the island of Great Britain, the northeastern part of the island of Ireland, and many smaller islands within the British Isles. The United Kingdom consists of four countries: England, Scotland, Wales, and Northern Ireland. The constituent countries have their own respective governments with the UK government being responsible for national defense and foreign affairs. It is the fifth largest economy globally and ranks 21st in global GDP per capita. Following years of negotiation, the UK officially withdrew from the European Union in 2021 but remains an important member of international organizations, including the G7 and NATO, as well as a permanent member of the United Nations. It is currently being challenged by demands for Scottish independence and the ongoing border dispute between Northern Ireland and the Republic of Ireland.
