Anglo-Celtic Commonwealth

The **Anglo-Celtic Commonwealth**, officially the **Commonwealth of England and Celtic Nations**, often referred to as the **Dual Republic**, the **(Insular) Commonwealth**, or simply **Britain**, or **CECN**, is a country in Europe off the north-western coast of the continental mainland. It comprises the two federations of  England and  Celtland. The Anglo-Celtic Commonwealth includes the islands of Great Britain, Ireland, it's surroundings,  Britanny in continental Europe, and many oversea territories all around the world. It shares a land border with  Rome through  Britanny and the Tridominium of  Greater Gibraltar; the latter belonging to  Rome,  Zarexium and  CECN themselves, also sharing a border with  Maghreb through  Ceuta and  Melilla; the military bases of  Akrotiri and Dhekelia border  Hellas on the island of Cyprus, the autonomous district of  Guyana borders  Benelux and  Venezuela in South America; otherwise, the Insular Commonwealth is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is 367,766 square kilometres (141,995 sq mi), with an estimated 2021 population of more than 80 million people.

The Commonwealth has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the  Kingdom of England (which included  Wales, annexed in 1542) and the  Kingdom of Scotland in 1707 formed the  Kingdom of Great Britain. Its union in 1801 with the  Kingdom of Ireland created the  United Kingdom of Great Britain and Ireland. Due to a war with  Zarexium, London lost the latter in 1863, leaving the present  Kingdom of Great Britain, which formally adopted that name in the same year. Almost 100 years later the two entities would find themselves being united once again. Although Britain did not emerge empty-handed from its war against the French, it was not a total victory and the economy was shacked. To counter the Irish idea of a Celtic federation, which at the time became very popular amongst the Scots, the Welsh and the Bretons, some socialist politicians proposed an Anglo-Celtic federation which would preserve the cohesion of the islands and rebuild Britain's economy. However, turning this plan into action in 1962 provoked a social split in the British society that would lead to civil strife in the British Revolution, which encompassed three to four million Royalists emigrating to the Dominions together with the royal family. Ultimately, it would take several decades for the economy to recover from all those crises.

CECN is a directorial republic with the Commonwealth Council, a six-member body, as head of state and government. Due to its complicated system, it is difficult to clearly define the relationship between the Commonwealth and the two federations of  England and  Celtland. The national capital is  Liverpool and the most populous city is  London, a global city and financial centre with a metropolitan area population of over 12 million. Other major cities include Birmingham, Dublin, Glasgow, Leeds, Manchester and Nantes. The island nation became the world's first industrialised country and was the world's foremost power during the 19th and early 20th centuries. In the 21st century, the Commonwealth retains considerable economic, cultural, scientific and technological influence. CECN has the world's seventh-largest economy by nominal gross domestic product (GDP), and the twelve-largest by purchasing power parity. It has a high-income economy and a very high Human Development Index rating, ranking eighth in the world. It also performs well in international rankings of education, healthcare, life expectancy and human development. It is a recognised regional power and is ranked sixth globally in military expenditure.

The Dual Republic is a member of the  Transuniversal Alliance of Nations (NATU), the  Council of Europe, the Group of Ten, the G16, the  United Nations, the  Defensive Council of Independent Nations (DCIN), the Organisation for Economic Co-operation and Development (OECD),  Interpol, and the World Trade Organization (WTO).
