This was shown in a viewscreen graphic on the USS Enterprise-D, taken from the Spaceflight Chronology, which further explained the attacks were by Romulans in the buildup to the Earth-Romulan War.
- Triacus marauder attacks on the worlds of Epsilon Indi (TOS: "And the Children Shall Lead")
- The Aquans had apparently been attacked by their progenitors, known as "air-breathers", centuries prior to 2269. (TAS: "The Ambergris Element")
- Destruction of Gol: prior to the Time of Awakening (ENT: "Kir'Shara")
- Andorian renegade action in the Triangulum system (TNG: "The Survivors")
Dialogue implies this happened during Picard's lifetime and most likely even during his Starfleet carreer.
- Wars on Earth over Black pepper, paprika, mustard seed, cayenne, and other such resources. (ENT: "Rajiin")
Involving the Klingon Empire[]
Since this battle was commanded by a Klingon Emperor called Sompek, and the last Emperor reigned in the mid-21st century, it can be assumed that the battle took place before that time.
- Failed Klingon invasion of the Breen: during the Klingon Second Empire (DS9: "'Til Death Do Us Part")
This was also ordered by a Klingon emperor, and thus most likely before the mid-21st century.
- Klingon annexation of Raatooras: some years before 2153 (ENT: "Judgment")
- Klingon conquest of Krios Prime: after 2152 (TNG: "The Mind's Eye")
- Battle of HarOs: before 2370 (TNG: "Parallels")

- An attack on Romulus: during the life of Kor, before 2372 (DS9: "The Sword of Kahless")
- Romulan boarding of ShiVang's flagship (DS9: "Once More Unto the Breach")
Martok's quote that he has hated Kor's "name for almost thirty years" would put his service on the flagship and the Romulan attack sometime in the late 2340s/early 2350s.
- Conquest of the Zora Fel (DS9: "Apocalypse Rising")
- Liberation of Vrax (DS9: "Apocalypse Rising")
- A Klingon-Romulan battle at Tranome Sar (TNG: "A Matter Of Honor")
- A Klingon-Romulan battle in which Klag's father was captured (TNG: "A Matter Of Honor")
- Romulan attack on a Klingon outpost (TNG: "Face Of The Enemy")
During Kahless' life[]
- Some inconsistencies exist concerning the exact dating of Kahless' life. See the note here for details.
- Kahless-led uprising against Molor
- Battle of Qam-Chee (DS9: "Looking for par'Mach in All the Wrong Places")
- Battle of River Skral (DS9: "The Way of the Warrior")
- Kahless slaying of the Fek'Ihri (DS9: "The Sword of Kahless")
- Battle at Three Turn Bridge (DS9: "Let He Who Is Without Sin...")
This battle might or might not be part of his uprising against Molor.
Involving the Romulan Star Empire[]
- Conflicts involving both the Romulans and the Klingons have been listed under the Klingon Empire section.
- A hundred year long war between the Vulcans and the Romulan Star Empire (VOY: "Death Wish")
This may refer to the Time of Awakening, during which the logicians led by Surak fought at least one war against "those who march beneath the raptor's wings".
- "A hundred campaigns" a centurion claimed to have fought together with his Commander, previous to 2266. (TOS: "Balance of Terror")
Romulan life spans were never specified, but are likely similar to Vulcan ones, i.e. about two centuries.
- A battle involving the Romulan commander Chulak at Galorndon Core before 2370. (VOY: "The Thaw")
- Battle of Vorkado: before 2377 (VOY: "Workforce, Part II")
Alternate timelines[]
- Nazi Germany conquest of Earth (TOS: "The City on the Edge of Forever")
- An alternate version of World War II (ENT: "Storm Front", "Storm Front, Part II")
- Nazi conquest of France, Belgium, and the Netherlands

- Nazi invasion of Russia and capture of Moscow

Given that the sinking of the USS Enterprise was thought to have left no survivors, it was probably also sunk as a result of a naval battle (as opposed to scuttling).
- Alternate reality invasion of Federation space by the Borg before 2370 (TNG: "Parallels")
- Federation-Klingon War: c. 2340s – 2366 (TNG: "Yesterday's Enterprise")

- Klingon Empire conquering of the Romulan Star Empire in the anti-time future (TNG: "All Good Things...")

- Xindi destruction of Mars, Alpha Centauri, and Vega colony
- Xindi destruction of a Human convoy in the Mutara system: 2165
- Battle of Ceti Alpha V: 2165
A few vaguely referenced incidents might also qualify:
- "The Visitor" showed hostilities between the Federation and the Klingon Empire, and while war was not mentioned, these seemed serious enough that Starfleet was forced to hand over control of Deep Space 9.
- Given Admiral Janeway's confidence in "Endgame", her assertion that the Borg are no longer a threat to the Federation as of 2404 might have been proven in combat.
- "Endgame" also mentioned a seemingly serious conflict between Voyager and the Fen Domar in the 2380s.
- "Shockwave" showed a future where Earth was in ruins in the 29th century, but did not specify if this was the result of direct conflict.

Other and unsure[]
- The vast majority of species assimilated by the Borg were presumably, at least briefly, in conflict with them.
- When taken together, the short life expectancies of Jem'Hadar, together with the fact that very few don't die in battle, would suggest that the Dominion is constantly involved in conflict, even beyond those seen. (DS9: "To the Death")
- A number of species were said to have once been warlike, even if no specific conflicts were named:

- During the Dominion War, several Starfleet missions into Cardassian space had not returned. While not explicitly said, presumably this was the result of battle. (DS9: "The Magnificent Ferengi")
- The Cardassian wars caused many deaths on Camor V. However, the exact cause was not explicitly stated. (TNG: "Bloodlines")

- Quark mentioned a Minnobia-Vek war as part of a plot, and given the circumstances most likely would not dare to make names up. (DS9: "Business as Usual")

- Quark alluded to Emperor Worf's plans for mass destruction, genocide, and other things. (DS9: "The Emperor's New Cloak")
