An alliance of nations previously existing as the European Union.
After WWIII, the Union formed into a federation and updated its governmental structure accordingly. Also called the European Federal States, the Federation of Europe or Europe, simply. Europe is an amalgamation of thirty or so nations, a long-standing alliance that has stood the test of time over and over again. Despite having prevented major losses during the War, the EU still found itself struggling to survive following both the Russian invasion and the nuclear strikes that hit the main cities of the member states and large military bases. Already a de facto federation, it took very little work to officially declare Europe a federal conglomerate, removing a number of obstacles to transnational cooperation and allowing the member states to assist each other effectively. Following a number of laws, the states of Europe managed to create an efficient system and quickly build up a powerhouse of financial, military and diplomatic might.
In varietate concordia.
Europe officially recognizes three languages, English, French and Spanish, although all of them are respected and local dialects are highly diverse. Official documents are primarily written in English, but translations are available in every language of the union. Rights and social matters are highly regarded and previous historical feuds based on concepts such as gender theory and abortion have largely been abandoned. Human rights are safeguarded tightly via very severe punishments and an extremely high-quality court system. Europe is extremely diverse, and as such, classification of culture is impossible - every nation within the alliance retains its own customs, cuisine, art and ideals. Every state in the union has its own differences, but most are harmonized by the Constitution of the European Federal States, a veritable "gigadocument" encompassing upwards of 300 regulations, the Charter of Fundamental Rights, the Treaty on the Functioning of the EU and the Treaty on the EU. The Federation is currently rated as the second most powerful technology powerhouse just after the PPS and several of the galaxy's largest corporations have their origin here.
The European Federation is extremely varied, and so national aesthetics, culture, architecture and so on have mostly remained the same. Some ideals are prevalent to all nations, however, such as adaptive reuse, the practice of repurposing and adapting older buildings with new purposes or additional, modern structures. Given how much damage was sustained during the war, this practice became a common way of restoring historical areas while both respecting them and providing housing and services during the post-war population boom.
European cities are clean, green, walkable, equipped with automated public transport, the occasional skycar route and, most of the time, a small spaceport. The European Transnational Maglev Network connects every major city in a matter of hours. Europeans are generally lively, active people, with a strong sense of community and a great willingness to help others. It's not surprising, then, that a saying has become popular among spacers:
If you're in trouble, call a Euro.
The federation relies on a highly capable military body, the European Federation Armed Forces, split into the Federal Navy, the Federal Army and the Federal Special Forces. The Federal Navy is the third most powerful navy in the galaxy without counting alien species, just after the American and the UN Navies.
The Navy is mostly based on a balanced doctrine, without relying on battleships and huge ships, instead deploying large fleets of versatile, fast vessels, armed with a variety of equipment to deal with most threats and generally focused on a more defensive stance. The Navy is divided in fleets that mostly base themselves around a specific planet or area of space, but they are loosely organized and capable of quick reassignment and movement. European ships are utterly ubiquitous in modern times, and it is common for travelers to spot a European ship mostly anywhere within known space while plotting their journeys. European ships are usually painted a dark blue and adorned with the circlet of stars that is present on their flag.
Naming conventions are as such:
Frigates are named after famous historical figures (EFNS Charlemagne, De Gasperi, De Gaulle, etc.)
Destroyers are named after mythological figures (EFNS Achilles, Agamennon, etc.)
Cruisers are named after European cities (EFNS Milan, Dunkirk, Dusseldorf, etc.)
