The skull of a Xindi-Avian

Xindi history was long and troubled; the Xindi were often characterized by inter-species conflict. The Xindi were a spacefaring civilization for at least 4,000 years, since the remains of 4,000 year-old Xindi-Avians were found on another planet. (ENT: "The Council")

Civil war and diaspora[]

For about a century, the different Xindi races fought for control of Xindus, their homeworld. At the end of this long war, the Xindi-Reptilians and the Xindi-Insectoids forged an alliance which resulted in the destruction of the planet, sometime during the 2030s. The Xindi-Avians were unable to evacuate when Xindus was destroyed. (ENT: "The Shipment") This began the era known to the Xindi as the Great Diaspora, as the various Xindi species that survived the destruction declared peace and sought to work together to find and establish a new homeworld.


Two "Guardians" in their native realm

They were unable to settle on a single new world, however, spreading across several worlds in the Delphic Expanse, including Azati Prime and others. It was around this time that the Xindi were first contacted by the transdimensional beings they dubbed the Guardians. The Guardians assisted the Xindi during the Diaspora, directing groups of refugees to appropriate planets and helping them avoid the dangers of the Expanse. The Guardians were responsible for the creation of the Xindi Council and kept it together during troubling times. (ENT: "The Council")

The Human threat[]

Xindi probe

The Xindi weapon probe fires on Earth in 2153.

In the 2140s, the Guardians contacted the Xindi Council, informing them that – in the 26th centuryHumanity would destroy their new homeworld, thereby using the Xindi for their purposes in the Temporal Cold War. As a result, the Xindi began developing a planet-destroying weapon, so they could wipe out Earth in a preemptive strike. A test strike against Earth in March 2153 resulted in the deaths of seven million people between Florida and Venezuela. Earth responded by sending the flagship of Starfleet, Enterprise, into the Delphic Expanse, in order to find the Xindi and stop them from launching their final weapon. (ENT: "The Expanse", "Azati Prime")

When Enterprise arrived at Azati Prime in January 2154 after a long and harrowing search for the weapon, the information Captain Jonathan Archer brought rocked Xindi civilization to its core. He revealed that the Xindi "Guardians" were actually the same beings responsible for the construction of the spheres found all across the Delphic Expanse, and that they were using the spheres to alter space in our universe to conform to their dimension's physical laws. They had foreseen that, in the 26th century, the United Federation of Planets would defeat their invasion force; the Sphere-Builders were trying to stop this from happening by destroying Earth, using the Xindi. (ENT: "Azati Prime")

Archer managed to convert Primate representative (and weapon designer) Degra to his cause and, with his help, brought Arboreal representative Jannar and the other Primate on the Council to his side as well. The Aquatics remained on the fence until Archer provided stronger evidence; they then provisionally sided with Archer's cause. The Reptilian representative Commander Dolim as well as his Insectoid colleague refused to accept Archer's story and stole the weapon rather than let the Council delay the launch. Fortunately for Earth and the future, Enterprise – working with the Primates, Arboreals and Aquatics – managed to stop the weapon from destroying Earth. Enterprise also destroyed the sphere network in the Delphic Expanse. (ENT: "The Forgotten", "The Council", "Countdown", "Zero Hour")

The Insectoids eventually rejoined the Council, after events indicated Archer's story was correct. The Xindi expressed gratitude toward Enterprise for showing them the truth, though reunifying after the fractures Archer's revelations had caused proved to be difficult. (ENT: "Zero Hour")

24th century[]

By the late 24th century, the Xindi were either members of the United Federation of Planets or close allies with them. with a Xindi-Arboreal serving aboard the USS Protostar in 2382 as a Starfleet officer. (PRO: "Last Flight of the Protostar, Part I")

By 2384, the Xindi-Reptilians ran Denaxi Depot near the Romulan Neutral Zone, the only major transportation hub in its sector. It was known to be a safe haven for smugglers and those who wished to disappear. They were also friendly to the Federation, Starfleet and Humanity, suggesting that the Reptilians ultimately accepted the truth about the Sphere-Builders and ceased any remaining hostilities they might've held towards their former enemies. (PRO: "Crossroads")

Alternate realities and timelines[]

In an alternate timeline, according to Daniels, the Xindi were intended to join the Federation; by the 26th century, Xindi were serving aboard Starfleet vessels and took part in the Battle of Procyon V against the Sphere-Builders. (ENT: "Azati Prime")
