The United Britannic Socialist Republics, commonly referred to Britannia or UBSR', is a nation situated on the islands of Great Britain and Éire in Europe.


The Kingdom of England was one of the three founding members of the UKBA along with the Irish states of Desmond (now named Munster) and Ulster. After a series of rebellions in Wales and the Hundred Years' War in France, the Isles needed stability long since absent after a parade of intemperate Norman rulers. After the Black Prince of Wales was defeated in the early 1410's, Wales rejoined England. After this, France was beseeched to end the War after the earlier King, King Henry IV of Lancaster died heir-less and the House of York, under Edward III took the throne. Eventually the war was ended and a status quo antebellum established. After the rise of the Western Church, The Acts of Union of 1425 sought to unify the nations of England (and Wales), and the Irish states of Munster and Ulster with the English Royal Crown Dependency of Dublin. Later, in a separate Acts of Union, Scotland was vassalized under the flag of Albion. In the 1430s, England and Ireland were wracked with what became known as "The Norman Rebellions", The largely Norman nobility in England and Southern Ireland rebelled against the largely Western Church locals and the the Royal family in attempt to depose the King, re-establish the Roman Catholic Church, and retaining Norman power in lieu of the growing power of the Anglo-Celts. The rebellion went on four five years before being decisively defeated at the battle of South Hampton. In 1445-46 The states of Munster and Ulster came into dynastic union and formed the Kingdom of Eire, simplifying the membership accords first set by the original Acts of Union. All members of Albion are founding members of the North Sea Trade Alliance (NSTA). The United Kingdoms' Navy is a dominating force in the North Sea, Baltic and North Atlantic Oceans.

Birth of the Western Church

Later, do to strife within the Catholic Church, several leading Bishops from Canterbury grew disenfranchised with the corrupted Roman Church. The Western European Church was born. Support was non existent in the early years, with the King of England himself rejecting the Church until the end of his life. But through constant preaching and the abolition of corrupt practices with in Catholicism, the populations of England, Wales and Scotland eventually committed to the Church, it was in these days that the United Kingdoms of Greater Albion were officially formed via Acts of Union. The Church then spread under the leadership of Pope Ian I of Eire to the shores of Castile and later to Prussia and the UNC. Currently the Church is meeting with Orthodox and Catholic leaders in effort to reconcile the Christian Faith.

The Assimilation of Eire and the birth of Britannia

After increased inefficiency in Eire and an incapable leadership, Albion stepped in and consolidated power. In this same year, the Parliament, by popular vote, voted to rename Albion into the Empire of Britannia to reflect the growing power and influence that Britannia had on the UKGA. The Empire had its trial by fire when the Invasion of the Oyo commenced later in the same year, 20,000 fighting men were deployed to fight the Oyo menace.

The War of the Grand Coalition

Britannia, was the second nation to join the war and was once, alongside Hispania and France, part of the Triple Alliance. After exiting a recent succession crisis, attacked in order to reaffirm its status as a major power and increase its colonial holdings, which were stunted by the Treaty of Westminster, which is now acknowledged as a Spanish tool that was used to expand its colonial empire without being threatened by France and Britannia. After little deliberation, Parliament, backed by a speech from the Emperor, decided to seize the opportunity and declared support for France, with a massive mobilization of forces not seen since the Austrian wars. Seeing the war as an opportunity to regain former glory, the morale of the armies, as well as popular support, was high. Many speculate that this war was the turning point in Britannic doctrine, which before, was largely isolationist. Britannia was instrumental in helping free the Mexaca peoples as well as guaranteeing protection to the recently rebelled Kingdom of Navarre.

Modern History

History in the later part of the 20th Century (except for the 90s) was pretty uneventful, Britannia was just stabilising as a country.

However, in 1961 Daniel McCenner founded the 'Britannia Communist Party,' at the age of 26. A year earlier his wife gave birth what will become the leader of the Britannia Communist Party, Conner McCenner. The first 20 years was a struggle for the Communist Party, only getting three seats in the 1976 Election. In 1980 Daniel McCenner died due to a heart attack, a young Conner McCenner (being only 20) took over the Communist Party and led it to glory. In the 1980 election they got two seats. In the 1984 election they got 33 seats. In the 1988 election they got 299 seats.

In 1992 the Communist Party was very powerful and won 800 seats. Connor McCenner renamed the country 'United Britannic Socialist States'. He said a very famous line at the winning speech: 'THE AGE OF BRITANNIA HAS COME!'. In the same year Britannia began making the standard of living higher, with roads and money invested in the economy. They also started researching nukes.
