===Temporal Cold War===
The [[Krenim weapon ship]], constructed by [[Annorax]], accomplished temporal incursions by pushing a target, anything from a molecule to a civilization, out of the [[space-time continuum]]. This essentially erases the target from history, changing the [[timeline]] to one in which it had never existed.

Numerous temporal incursions occurred as part of the Temporal Cold War. Multiple factions, each one vying for control, attempted to change history to suit their own ends. Examples include the [[Suliban Cabal]]'s [[Humanoid Figure|mysterious benefactor]] attempting to sabotage the {{EnterpriseNX}}'s mission, the [[Sphere Builder]]s attempting to manipulate the [[Xindi]] into destroying [[Earth]], and [[Vosk]] collaborating with the [[Nazi]]s in [[1944]].

Arriving in [[Earth]] orbit through a [[temporal vortex]], the sphere immediately began firing upon [[Zefram Cochrane]]'s launch facility in central [[Montana]], but was itself destroyed by the crew of the {{USS|Enterprise|NCC-1701-E}}, who had followed the [[Borg]] through the vortex.

Careful calculations need to be performed prior to such an incursion if one is trying to achieve a specific result.

Erasing something as simple as a rogue [[comet]] in {{USS|Voyager}}'s path, as [[Chakotay]] had suggested, would have eliminated 8,000 civilizations in a radius of 50 [[light year]]s, because fragments from that comet had seeded life in the [[sector]] billions of years ago. Indeed, Annorax was never able to achieve his goal of fully restoring the [[Krenim Imperium]] despite hundreds of temporal incursions. Ultimatly all of his temporal incursions were erased and his goal of restoring his wife was completed when Captain Janeway destroyed the Temporal Weapons Ship and erased it from history by ramming Voyager into it.

AT: "xx" Temporal incursion was the term used of an act of timeline alteration. As of the 29th century, there were agencies specifically tasked with protecting the timeline from any changes caused by time travel, such as the Temporal Integrity Commission, and the temporal agents of the 31st century. (VOY: "Relativity"; ENT: "Carpenter Street")

The Krenim scientist Annorax used the energy beam of his weapon ship to initiate temporal incursions. (VOY: "Year of Hell")

The level of alteration to the timeline after incursions was measured by 29th century Starfleet operatives in levels of incursion factors. For example, an incursion factor of 0.0036 was considered only a minor change to the timeline. (VOY: "Relativity") The Krenim also probed the continuum after an incursion and calculated the level of temporal restoration in comparison to the original timeline in percentages. (VOY: "Year of Hell")

Examples

Temporal Cold War

Numerous temporal incursions occurred as part of the Temporal Cold War. Multiple factions, each one vying for control, attempted to change history to suit their own ends. Examples include the Suliban Cabal's mysterious benefactor attempting to sabotage the Enterprise NX-01's mission, the Sphere Builders attempting to manipulate the Xindi into destroying Earth, and Vosk collaborating with the Nazis in 1944. These factions were opposed by Temporal Agents, who represented themselves to the crew of Enterprise in the form of Daniels, who would often assist the crew in protecting the timeline. (ENT: "Shockwave", "Azati Prime", "Storm Front")

The Borg

In 2373, a Borg sphere traveled back in time to April fourth, 2063, in an attempt to prevent Humanity's First Contact with extraterrestrials and assimilate the Human race at a time period in which they were ill-equipped to offer resistance. Arriving in Earth orbit through a temporal vortex, the sphere immediately began firing upon Zefram Cochrane's launch facility in central Montana, but was itself destroyed by the crew of the USS Enterprise, who had followed the Borg through the vortex. The crew subsequently assisted Cochrane in making repairs in time for his scheduled launch, ensuring that a Vulcan survey ship detected his warp signature, making First Contact on April 5th. (Star Trek: First Contact)

The events of this incursion constituted a Pogo paradox, in which interference to prevent an event actually triggers the same event. It also set into motion a chain of events in which a group of surviving drones were revived in 2153, and subsequently sent a message to the Delta Quadrant, where it was received by the Collective in the 24th century, alerting the Borg as to the location of Earth. (ENT: "Regeneration"; VOY: "Relativity")

Annorax

Temporal incursion

The Krenim weapon ship initiates a temporal incursion against the Ram Izad homeworld

Annorax, a Krenim scientist, initiated a multitude of temporal incursions during his quest to restore the Krenim Imperium to power. Using a massive weapon ship to literally erase objects from history, he attempted to manipulate the timeline in order to ensure Krenim superiority. His efforts met with failure, however, when erasing the Rilnar civilization from the timeline had disastrous effects for the Imperium. For over a century, Annorax and his crew attempted to restore the Imperium by erasing ships, colonies, and even entire civilizations from history. In 2374, Annorax was opposed by the crew of the USS Voyager, who were attempting to cross through Krenim space on their journey back to the Alpha Quadrant. Eventually, as a result of massive battle damage, a temporal incursion was initiated within the weapon ship itself, erasing it, and all of the damage it had caused to history, from the timeline. (VOY: "Year of Hell", "Year of Hell, Part II")

Voyager

During its seven-year voyage through the Delta Quadrant, the starship Voyager was involved in numerous temporal incursions, including those involving the Krenim. Some notable examples include:

Nero

Narada

The Narada emerges from the black hole in the year 2233

In the year 2387, when a supernova threatened to destroy the entire galaxy, Ambassador Spock utilized red matter to create a black hole with which to absorb the exploding star. Although Spock's efforts were successful, he was too late to save Romulus, which was destroyed. Nero, captain of the Romulan mining vessel Narada, confronted Spock, holding him responsible for the destruction of his homeworld. During the confrontation, both vessels were pulled into the black hole and transported back through time, the Narada arriving in the year 2233, resulting in the creation of an alternate reality. Upon emerging from the black hole, Nero immediately attacked the USS Kelvin, setting into motion a chain of events causing a drastic difference in the histories of the two timelines. Spock, having entered the black hole only moments after the Narada, emerged in the year 2258, and was immediately captured by Nero, who forced Spock to witness the destruction of Vulcan at Nero's hands. Eventually, with assistance from Spock, James Kirk and Spock's alternate reality-counterpart were able to put a stop to Nero's efforts to perform the same action on every Federation world, destroying the Narada with another artifically-created black hole.
