The majority of new nations are the result of the strengthening of supranational bodies such as the European Union. This has facilitated the peaceful breakup of existing multicultural states whose regions had strong national or cultural aspirations, since many of the benefits gained as members of their original union or federation are now provided by the superstate. A very short list of the many new nations that exist in 2155 include:

• Catalonia (formerly part of Spain, an E.U. member).
• East Timor (formerly controlled by Indonesia).
• Konigsberg (city-state in the Baltic region, formerly part of the Russian Federation as Kaliningrad).
• Maritime Union (ex-Atlantic provinces of Canada, excluding Newfoundland; now an E.U. member, along with Quebec and Newfoundland).
• Republic of the Moluccas (formerly part of Indonesia).
• Scotland (formerly part of the United Kingdom).
• Union of Alberta and British Columbia (ex-Canadian provinces).
• Wallonia (formerly part of Belgium, an E.U. member).
