Section 31 (unofficial)

United Earth was a planetary state created through the unification of Earth in the 22nd century, following first contact with Vulcans in 2063. United Earth continued to exist as a political subdivision of the United Federation of Planets when its government helped found that interstellar state in 2161. (Star Trek: First Contact, Star Trek: Enterprise)


By the 2150s, the United Earth government was coterminous with all major settlements made by Humanity. This included all territory on Earth itself, after all previous Human governments united into one organization. United Earth controlled all of the Sol system, but in the 2150s, the organization had begun to spread to other nearby star systems.

Planetary bodies that had major Human settlements or military installations on them in the 2150s included:

In the Sol system:

In other solar systems:

In ENT: "Twilight", in an alternate timeline in which Jonathan Archer lost his long-term memory, Earth was destroyed by the Xindi weapon in 2154. When describing the Xindi's drive to exterminate Humanity, a future T'Pol explained to Archer that the Xindi had not stopped with the destruction of Earth (and thus, Luna) but went on to destroy every major Human colony which existed in 2154, which she then listed as Mars, Alpha Centauri, and "Vega colony." It is uncertain, from T'Pol's comments, if these four planets were absolutely the only worlds colonized by Humans, or if there may have been smaller colonies/outposts besides them. As for Deneva, TOS: "Operation -- Annihilate!" states that the planet was colonized by Humans by the 2150s. Furthermore, in ENT: "Horizon", it is stated that Earth Cargo Service trading ships were making runs to the colony in 2153.

In the first half of the 22nd century, the most significant Human presence in space beyond the Sol system itself was in the form of "Boomers", independent Human traders that formed a merchant marine using crude, generationally-owned starships that took years to travel between destinations. While nominally under the control of the Earth Cargo Authority, by their very nature, the Boomers were frontiersmen without any real oversight from Earth and generally handled their own affairs. In a sense, these small (with approximately two dozen crewmen on the common Y-class freighter) and mobile ship-borne communities could be seen as "colonies" of a sort. During the second half of the 22nd century, as faster warp drives became more commercially available, travel time between destinations was cut down from years to months or weeks, and response by official United Earth Starfleet ships was, for the first time, made a practical reality; the independent frontier lifestyle of the Boomers gradually came to an end. (ENT: "Fortunate Son")


As a planetary state, United Earth was represented in the Coalition of Planets and, later, the United Federation of Planets. Government officials included ministers. (ENT: "Demons")

Given the existence of the "minister" title, it is likely that the United Earth is a parliamentary government, possibly led by a prime minister.

Even after United Earth was formed, many nation-states and confederations of Earth retained their individual identities. These included the African Confederation, Canada, the European Alliance, Russia, and the United States of America. (TNG: "The Naked Now", "The Price", "Conundrum", "Lower Decks"; VOY: "Imperfection")

United Earth had many agencies. This included an early form of Starfleet (prior to 2161), Military Assault Command Operations (MACO), the United Earth Space Probe Agency, and the United Earth Diplomatic Corps, the latter of which was responsible, among other things, for running the United Earth Embassy on Vulcan during the 22nd century. (ENT: "Broken Bow", "The Expanse", "The Forge"; TOS: "Court Martial")

As evidenced by the first draft script of the ultimately undeveloped film Star Trek: The Beginning, a United Earth agency called the "United Earth Stellar Navy" (abbreviated as "UESN" and with an academy of its own) was at one point intended to have been established. [1]


The term "United Earth" was used in relation to a New United Nations declaration of 2036. (TNG: "Encounter at Farpoint") The phrase was used as a name as early as 2067, for the United Earth Space Probe Agency. (TOS: "Court Martial"; VOY: "Friendship One")

By 2079, all "United Earth nonsense" was abolished in the post-atomic horror, at least in some areas of the planet. (TNG: "Encounter at Farpoint")

The activities of the European Hegemony, which existed in the 2120s, led to the formation of United Earth. (TNG: "Up The Long Ladder")

According to the official Star Trek website, United Earth may have come into being in 2113. However, this detail has never made it into canon. The date is cited to Star Trek: First Contact by some sources (citation needededit), but except for Deanna Troi speaking of "poverty, disease, [and] war" being gone in fifty years, there is no line in the movie suggesting a unification.

In 2150, the last of Earth's nations joined United Earth, making it truly global. (TNG: "Attached")

It is a common misbelief that Australia was the last state to join the United Earth government in 2150, but Australia holding out was only used by Beverly Crusher as a hypothetical example when discussing the eligibility of the fractured planet Kesprytt with Jean-Luc Picard in TNG: "Attached".
It is, however, possible that the United Earth government was founded prior to 2150 and that this was the year that the last remaining independent nations chose to join. This is supported by various episodes of Star Trek: Enterprise, such as "First Flight", which established that the United Earth Starfleet existed in the 2130s and 2140s.

Minister Nathan Samuels represented United Earth at talks for the Coalition of Planets in 2155. (ENT: "Demons", "Terra Prime")

It is consistent with the term "federation" (as in "United Federation of Planets") to presume that the United Earth government remained in place following the founding of the United Federation of Planets. Further evidence in this regard includes the 23rd century existence of a United Earth Space Probe Agency in TOS Season 1 and other agencies noted above under the jurisdiction of a Terran global government within the UFP.


Archer's ambassadorship is from a 2268 biographical screen seen in "In a Mirror, Darkly, Part II".


Background informationEdit

The logo for United Earth was designed by Michael Okuda. "For a long time, I was actually dreading designing the United Earth logo," he admitted, "because it was such an important thing [....] But, when it came time to design, you suddenly realize, 'Well, you want to point toward the Federation [in design lineage] and you want to show Earth,' so it's actually created very quickly." (ENT: "The Forge" audio commentary, ENT Season 4 Blu-ray)


In the novel Articles of the Federation, it is revealed that United Earth came into existence in 2130, with the signing of a document called the Traité d'Unification at the Place de la Concorde in Paris, France; the Place de la Concorde later becomes the site of the Palais de la Concorde, the Federation's capitol building. The novel The Good That Men Do followed the notion that the last nation to become part of United Earth was Australia.

The short story "Eleven Hours Out" in the anthology Tales of the Dominion War indicates that United Earth is a parliamentary system, as an unnamed Prime Minister of United Earth is described as touring the devastated city of San Francisco after the Breen attack of 2375, along with the President of the United States and Federation President (established in a subsequent novel, A Time to Kill, as Min Zife of Bolarus). The novel Starfleet: Year One features a character named Lydia Littlejohn, who served as President of United Earth during the Earth-Romulan War. If the apocryphal stories are accepted as being in continuity with one another, this may be an indication that United Earth utilizes both presidential and prime ministerial offices, akin to the systems of the present-day State of Israel or Italian Republic. (In such systems, the President is usually the head of state, and the Prime Minister is the head of government.)

The Star Trek: Enterprise novel Last Full Measure reveals that United Earth was involved in a number of very low-level conflicts with factions on alien planets (not full governments) and a rebellion on Mars in the years prior to the Xindi attack of 2153; MACO forces played a decisive role in those conflicts. United Earth's military is also revealed to have inherited the martial funeral ceremony of flag folding.

According to an unseen It's Federation Day! article created for the Picard family album in Star Trek Generations, Thomas Vanderbilt was the United Earth ambassador to the Federation Founding Ceremony.
