Editing Delta Quadrant (section)

==24th century political makeup== 
The major power in the Delta Quadrant, until at least 2377, was the Borg Collective. In addition to a vast swath of territory which they had completely assimilated, the Borg used a transwarp network to routinely visit different points scattered throughout the quadrant. Following the Borg-Species 8472 War, the insurrection led by Axum, the destruction of the transwarp network and the destruction of Unimatrix 01, it is unclear how the Borg's status in the Delta Quadrant has been altered. (VOY: "Scorpion", "Unimatrix Zero", "Endgame") 

Other alien species that control significant areas of the quadrant include, among others, the Vidiians, the Devore, the Kazon, the Voth, the Hirogen, the Hierarchy and the Malon. Species 8472 had also established a presence in the Delta Quadrant until they returned to fluidic space. (Star Trek: Voyager) 

The political power of the Krenim Imperium depends largely on its temporal weapons, and as such its influence may be altered dramatically by its own manipulation of the timeline. (VOY: "Year of Hell")
