This is a revised version of a previous deviation of the same name which I have deleted because, frankly it sucked.
The European Federal Union (EFU or EU) is a Parliamentary semi-presidential federal republic of 61 terrestrial provinces, located in Europe. Born out of a commitment to regional stability during the Flood, the EU was established by the Second Treaty of Maastricht on 1 November 2014 upon the foundations of the pre-existing European Union (E.U.). With almost 1 billion citizens, the EU combined generates an estimated 30% share (US 58.4 trillion in 2068) of the nominal gross human product.
The EU traces its origins to the European Coal and Steel Community formed among six countries in 1951 and the Treaty of Rome in 1957. Since then the union has grown in size through the accession of new countries, and new policy areas have been added to the remit of the EU's institutions.
A four tier Republic, Europe is one of the few human civilizations left that still permits regional Monarchs as a ceremonial level of local government; the most famous being the British Crown which still technically has dominion over the whole of the British Isles.
