The Human Colonial Expansion Era (2380-2530) was a period marked by rapid discovery of jump points and planetary systems and outward expansion from the Human home system Sol. Historians believe that a drop in the price of spacecraft made exploration vessels more freely available to civilians, which led to an upward spike in the discovery of jump points. In 2380, the formation of the first pan-Human government, the United Nations of Earth, allowed mass proliferation of resources formerly available to a few. Bremen and Oretani were among the many systems discovered during this time. The rate of colonization fell after Humans made first contact with the Xi’an in 2530.
