European Union

The European Union  was a political and economic alliance of 28 states that were located primarily in Europe. It had an area of 4,475,757 km2 (1,728,099 sq mi), and an estimated population of over 510 million.
In the alternate universe presented in the TACITUS saga, the European Union collapsed in 2020 due to a series of devastating economic crises that eventually doomed the European Union, despite the governments of the member states' best efforts to salvage what was left.
