The European Union (EU) is a political and economic union of 27 member states, located primarily in Europe. It was established by the Treaty of Maastricht in 1993 upon the foundations of the pre-existing European Economic Community.
The United Kingdom voted to leave the European Union in 2016. Not long after, Scotland left the U.K. and retained membership in the E.U. The remainder of the U.K. was still trying to figure out what to do with itself in 2031.
In the home timeline, the European Union had grown to resemble a single state politically over the course of the 21st century. However, national and cultural differences remained, and each country still seemed to have its own sense of national identity.
