The Union of Yuktobanian Republics (Yuktobanian: Союз Юктобанианских Республик), also called Yuktobania (Yuktobanian: Юктобания), was a communist nation on the planet of Arden in the Outer Rim Territories, later conquering the entire star system after defeating all other nations on the planet. It was a communist state, a union of several socialist republics located on the northeastern half of one of the three major continents of the planet. Eventually, it covered the globe. The Union was a rival of several other nations, the Osean Federation, the Kingdom of Sapin, the Belkan Empire, the Federal Republic of Estovakia, and the Nordland Free State, up until the Hundred Day War.
