A once proud nation of ancient times, the United Kingdom became a hermit state after leaving the European Union in 2020 A.D, focusing on internal revitilisation of its economy and industrial power. The United Kingdom refused alliance with the United States of North America and the United European States, instead remaining independent of the major global superpowers.

During the Fossil Wars, the UK began its own project to abandon the dying Earth, leading to the development of a vast orbiting facility - originally intended as a deep-space mining starship - known as UK1. The United Kingdom would eventually leave the Earth under its own flag sometime in the 22nd century. Very little data is available on the ultimate fate of the United Kingdom at this time.
