* At this time, all empires begin building base stations along their borders, replacing previous haphazard networks of various types and sizes of bases. This tends to solidify the borders over the next two decades.<ref name="PD20"/>

==Y121==

==Y124==
* The last of the [[Romulans (SFU)|Romulan]] "Old Series" mauler ships is destroyed in combat. The weapon, which needed too much power to be used effectively, was regarded as a failure. The design will be resurrected when [[Klingons (SFU)|Klingon]] [[warp drive (SFU)|warp engines]] provide the Romulans with a better source of power for their ships.<ref name="PD20"/>

==Y125==
* The [[Lyrans (SFU)|Lyrans]] attack the [[Kzinti (SFU)|Kzinti]] in the [[Kzinti-Lyran Wars (SFU)#Third War|Third Kzinti-Lyran War]] with part of their fleet, taking advantage of the [[Klingon-Kzinti Wars (SFU)#Third War|Third Klingon-Kzinti War]].<ref name="PDOne"/>
* The [[Gorn-Romulan Wars (SFU)#Fourth War|Fourth Gorn-Romulan War]] ends in a [[Gorn (SFU)|Gorn]] victory. The Gorn occupy some [[Romulan Star Empire (SFU)|Romulan]] territory to establish a clearly defined border, and destroy Romulan bases used to launch aggression.<ref name="PD20"/>
* The [[Federation Council (SFU)|Federation Council]] votes for a massive program of exploration toward the unexplored and uninhabited coreward regions. [[Aurora III (SFU)|Aurora III]] becomes the staging area for this program.

* The [[United Federation of Planets (SFU)|Federation]]'s [[Aurora III (SFU)|Aurora]] colony disappears mysteriously after sending a report of a very unusual cosmic storm. Every starship in the sector is sent to investigate but finds nothing; the entire [[Aurora system (SFU)|Aurora system]] has disappeared: star, planets, asteroids, bases, colonists — everything! The [[Federation Council (SFU)|Federation Council]] attempts a cover-up, but the news leaks. The resignation of pro-exploration members of the Council delays such exploration for decades. A century will pass before Aurora is found in the [[Omega Octant (SFU)|Omega Octant]].<ref name="PD20"/>

==Y131==
* The [[Klingon-Kzinti Wars (SFU)#Third War|Third Klingon-Kzinti War]] ends, with inconclusive results.<ref name="PDOne"/>

The Highlanders Prime Team, under the command of [[Kelleret, Sheroc (SFU)|Sheroc Kelleret]], liberates the starliner with no civilian fatalities.<ref name="PDOne"/> While the Orions fought to the death rather than surrender, Orion propaganda convinces many that a vengeful Prime Team executed the pirates.<ref name="PD20"/>

==Y132==
* [[Hydrans (SFU)|Hydran]] agents<ref name="PDOne"/> from the Lost Colonies<ref name="PD20"/> begin infiltrating [[Klingon Empire (SFU)|Klingon]]-occupied planets of the [[Hydran Kingdom (SFU)|Kingdom]].<ref name="PDOne"/>

==Y135==
* [[Hydrans (SFU)|Hydrans]] from the Lost Colonies under King [[Hydraxan XI (SFU)|Hydraxan XI]] attack the [[Klingon Empire (SFU)|Klingon]] satellites over the Hydran planets. In a swift campaign lasting only a few weeks, the [[Hydran Kingdom (SFU)|Hydran Kingdom]] is restored. The personal popularity of Hydraxan XI makes him "unacceptable" to the guilds, and he dies under mysterious circumstances. While [[Hydraxan XII (SFU)|Hydraxan XII]] ascends the throne, the guilds solidify their power.<ref name="PDOne"/>
* The [[Kzinti (SFU)|Kzinti]] field the first battle tug, which defeats an [[Orions (SFU)|Orion]] attack on a convoy.<ref name="PD20"/>

For reasons that remain obscure, four new kings take the throne in less than a year. The last, [[Hydraxan XVI (SFU)|Hydraxan XVI]], lasts for two years.<ref name="PDOne"/>

==Y142==
* The [[Federation-Kzinti Wars (SFU)#Second War|Second Federation-Kzinti War]] ends with no change in the border.<ref name="PDOne"/>
* The [[U.S.S. Enterprise NCC-1701 (SFU)|U.S.S. ''Enterprise'' NCC-1701]], responding to a falsified [[distress signal (SFU)|distress signal]], discovered that [[Talos IV (SFU)|Talos IV]]'s surviving [[Talosians (SFU)|inhabitants]] possessed powerful [[telepathy (SFU)|mental abilities]], could control humanoid minds with illusions, and were seeking [[slavery (SFU)|slaves]] to help them rebuild their world. The ship escaped,<ref name="TOS00"/> but [[Star Fleet Captain (SFU)|Captain]] [[Christopher Pike (SFU)|Pike]] recommended that the planet be placed under the strictest quarantine possible.<ref name="TOS16A"/><ref name="GPDFed"/>

==Y143==
* The brief [[Hydran-Lyran Wars (SFU)#Fourth War|Fourth Hydran-Lyran War]] begins and ends as the [[Hydran Kingdom (SFU)|Hydrans]] recapture two planets from the [[Lyran Star Empire (SFU)|Lyrans]].

Gerard]], whom they take with them. The Marquis (the Kzinti noble in charge of the [[United Federation of Planets (SFU)|Federation]] border) captures and executes the renegades to preserve peace, but he cannot return Gerard without explaining what the samurai had planned to do with him. Gerard is raised as a son of his own house.<ref name="PDOne"/>

* A [[Kzinti (SFU)|Kzinti]]-[[Hydran Kingdom (SFU)|Hydran]] Treaty is signed. Each pledges to attack the [[Klingon Empire (SFU)|Klingons]] and/or [[Lyran Star Empire (SFU)|Lyrans]] if the other is attacked by them. The Klingons and Lyrans sign a joint defense treaty six weeks later. Many Lyran nobles oppose this treaty, resulting in a sporadic civil war.<ref name="PDOne"/>

==Y157==
* A [[Gorn (SFU)|Gorn]]-[[United Federation of Planets (SFU)|Federation]] "war" starts<ref name="SFBDE"/> as the result of a small incident where two brash young captains shoot first and face embarrassing questions later.<ref name="TOS19"/> Both fleets mobilize, but no space combat takes place. The [[Romulan Star Empire (SFU)|Romulans]] attempt to disrupt treaty negotiations,<ref name="SFUSH52"/> but the "war" ends six weeks later<ref name="SFBDE"/> with the [[Treaty of Algoran (SFU)|Treaty of Algoran]].<ref name="PDOne"/> The [[United Federation of Planets (SFU)|Federation]] apologizes for entering the territory of the previously unknown Gorn, while the Gorn pay reparations for the colony destroyed in a ground raid and imprison an officer who used excessive force.<ref name="PD20"/>

All previous wars had been small (mostly consisting of border raids) but new logistical systems developed in this war (notably the semi-portable "mobile base") will make actual invasions of enemy territory possible. Fighters are deployed by the Kzinti in large numbers for the first time, establishing the concept of "attrition units" which make it possible to fight savage battles without losing quite so many ships that take years to build.<ref name="PD20"/>
* The [[United Federation of Planets (SFU)|Federation]], anxious to reduce the threat posed by the [[Klingon Empire (SFU)|Klingons]], shifts fleet units to the Klingon border and discusses a limited action with the [[Organians (SFU)|Organians]] to restore the balance of power. This is, however, a hoax intended to influence the Klingons to negotiate an immediate settlement to end the war, as the Federation would never consider military power as a solution to the problem. The plan backfires.<ref name="PDOne"/>

These increase pressure on the [[United Federation of Planets (SFU)|Federation]] border.<ref name="PDOne"/> The Federation transfers ships back from the Klingon border to the Romulan border. This allows the Klingons to transfer ships to fight the [[Kzinti (SFU)|Kzinti]].<ref name="SFBDE"/> The Federation's attempt to use the "threat of force" as a substitute for simple force has failed<ref name="PDOne"/> and planted the seeds of the [[General War (SFU)|General War]].<ref name="PD20"/>

* The first [[Klingon Empire (SFU)|Klingon]] ships are delivered to the [[Romulan Star Empire (SFU)|Romulans]] under the new treaty.<ref name="SFBDE"/>

==Y162==
* The [[U.S.S. Kongo NCC-1710 (SFU)|U.S.S. ''Kongo'']] is converted to a command cruiser<ref name="SFUPD20Modern"/> before being pursued by the [[Klingon Empire (SFU)|Klingon]] frigate [[I.K.V. Audacity (SFU)|I.K.V. ''Audacity'']].<ref name="SFUSL60"/>
* The [[Kzinti (SFU)|Kzinti]] noble known as "The Marquis," his health failing, sends [[Gerard, William (SFU)|William S.

* [[Kumerian, Ardak (SFU)|Ardak Kumerian]] assumes command of frigate ''[[I.K.V. Vigilance (SFU)|Vigilance]].'' Due to a combination of circumstances, history will record more about him than any other [[Klingon Empire (SFU)|Klingon]] officer.

==Y170==
* The [[Klingon Empire (SFU)|Klingon]] [[D-6 class (SFU)|D-6 class]] battlecruiser ''[[I.K.V. Destruction (SFU)|Destruction]]'' mutinies and is interned at [[United Federation of Planets (SFU)|Federation]] [[Starbase 16 (SFU)|Starbase 16]]. It is returned to the Klingons the next year, and the Klingons are outraged that the Federation dismantled the Ubitron Interface Module and want to declare war, but are restrained by the [[Organians (SFU)|Organians]]. [[Kumerian, Ardak (SFU)|Ardak Kumerian]], captain of the ''Destruction,'' is demoted in disgrace and sent to command the penal frigate ''[[I.K.V. Insufferable (SFU)|Insufferable]].''

The [[Klingon Empire (SFU)|Klingons]] declares war on the [[United Federation of Planets (SFU)|Federation]] and attack the border with hundreds of ships. It is unknown if the simply Klingons took advantage of the Organians' departure or if the Organians left because they knew the Klingons were going to start a major war. The Federation cruiser [[U.S.S. Hood NCC-1707 (SFU)|U.S.S. ''Hood'']] is reported destroyed by three Klingon cruisers,<ref name="SFUSH19"/> but the saucer returns to Federation lines in 2574.<ref name="SFUPD20Modern"/>
* Under pressure from the invading [[Klingon Empire (SFU)|Klingons]], the [[Orions (SFU)|Orion]] semiautonomous zone within the [[United Federation of Planets (SFU)|Federation]] briefly declares its independence and neutrality.

* [[Kraknora (SFU)|Kraknora]], a [[Klingon Empire (SFU)|Klingon]] penal colony, revolts. A task force is sent to quell the rebellion, but is never heard from again. ISF ships sent to investigate find the entire star system missing. Klingon scientists compare this event to the disappearance of the Federation's [[Aurora III (SFU)|Aurora colony]] 41 years earlier, but remain as baffled as their Federation counterparts.<ref name="SFUPD20Modern"/>

==Y172==
* The [[United Federation of Planets (SFU)|Federation]] responds to the [[Klingon Empire (SFU)|Klingon]] attack with raids by new carriers. Federation fleets are sent to assist the [[Kzinti (SFU)|Kzinti]], and a Federation expedition, Operation Hydra, unsuccessfully attempts to reach the [[Hydran Kingdom (SFU)|Hydrans]]. In an unusual case, a group of pirates is trapped bzetween Klingon and Federation fleets<ref name="SFUSH61"/> fighting on the border. [[O'Kay, Deth (SFU)|Deth O'Kay]] carries a contract cargo to Hydran territory; he is betrayed and attacked by the Hydrans, but wins.<ref name="SFUPD20Modern"/>

==Y173==
* With their invasion running out of steam, the [[Klingon Empire (SFU)|Klingons]] convince the [[Romulan Star Empire (SFU)|Romulans]] to declare war on the [[United Federation of Planets (SFU)|Federation]] and to launch a massive attack. Federation [[Star Fleet Commodore (SFU)|Commodore]] [[Stocker (SFU)|Stocker]] discovers the invasion and launches a preemptive attack with the ''[[U.S.S. Lexington NCC-1703 (SFU)|Lexington]],'' catching a Romulan squadron unprepared and badly mauling it.<ref name="SFUSH02"/> Another Federation squadron is ambushed at [[Denebola (SFU)|Denebola]] during treaty negotiations with an [[Orions (SFU)|Orion]] base.

The [[Hyran Kingdom (SFU)|Hydrans]] have co-belligerent status with the Grand Alliance but are not formal allies.<ref name="SFUPD20Modern"/>

* The [[Hydrans (SFU)|Hydrans]] begin a series of counterattacks in an attempt to drive the [[Klingons (SFU)|Klingons]] and [[Lyrans (SFU)|Lyrans]] out of their territory. Fighting is fierce, and many ships on both sides are destroyed. Several Klingon boom sections, detached from ships lost in action, are gathered at an advanced Klingon base for eventual return to the shipyards at [[Klinzhai (SFU)|Klinzhai]]. When the Hydrans begin another offensive, the Klingon sector commander decides to evacuate the booms. [[Klingon Lieutenant (SFU)|Lieutenant]] [[Kilgore (SFU)|Kilgore]] is assigned to organize the convoy, and he fortuitously arranges for an escort. The Hydrans detect the convoy and launch an attack, but decide they can't risk their ships in a direct assault. The [[Cavalier class (SFU)|''Cavalier'' class]] [[H.M.S. Restoration (SFU)|H.M.S. ''Restoration'']] and its escort, instead, launch their fighter group in an effort to catch and destroy the retreating Klingons. In short order, the entire force of Klingon fighters is destroyed, along with their carrier and one of the escorts. The Hydrans are only able to destroy one of the booms before they are forced to disengage by the Klingon reinforcements, the [[I.K.S. War King (SFU)|I.K.S. ''War King,'']] [[I.K.S.

The Tholians tentatively accept membership in the Grand Alliance.<ref name="SFUPD20Modern"/>
* The [[Insterstellar Concordium (SFU)|Interstellar Concordium]] begins incursions into [[Romulan Star Empire (SFU)|Romulan]] and [[Gorn (SFU)|Gorn]] territory. These increase over time.<ref name="SFUPD20Modern"/>

==Y177==
* [[Kurlak, Vulkalis (SFU)|Vulkalis Kurlak]], commander of the Tholian Border Squadron, finds himself as a fleet commander without ships in a backwater of the war. Amassing hundreds of fighters, he attacks the [[Tholian Holdfast (SFU)|Tholians]], exposing their weakness. Exploiting his success, the [[Coalition (SFU)|Coalition]] launches "Operation Nutcracker" to destroy the Tholians once and for all. Besieged, the Tholians allow ships of their allies to enter the Holdfast, but only those of the [[Gorn (SFU)|Gorn]] and [[Kzinti (SFU)|Kzinti]] (since they would not pose as much of a threat after the War).<ref name="SFUPD20Modern"/>

==Y178==
* The [[Neo-Tholians (SFU)|Neo-Tholian]] 312th Battle Squadron arrives. After these ships get into action, "Operation Nutcracker" begins to break down.<ref name="SFUSH22"/>
* Direct contact between [[Klingon Empire (SFU)|Klingons]] and [[Romulan Star Empire (SFU)|Romulans]] is broken and will never be reestablished. This causes serious logistical problems for the Romulans; they can no longer obtain an adequate supply of spare parts for their Klingon-built ships, and there is insufficient Romulan production available to make up for the lost shipments.<ref name="SFUPD20Modern"/>
* A [[Gorn (SFU)|Gorn]] offensive culminates in the disastrous [[Battle of Delmac (SFU)|Battle of Delmac]]. The Gorn carrier ''[[Archaeopteryx (SFU)|Archaeopteryx]]'' escapes from a [[Romulan Star Empire (SFU)|Romulan]] trap.<ref name="SFUSH21"/>
* [[PX123 (SFU)|PX123]], an [[Interstellar Concordium (SFU)|Interstellar Concordium]] mining colony, disappears in the same fashion as the [[Aurora system (SFU)|Aurora]] and [[Kraknora system (SFU)|Kraknora]] systems did in earlier years. Investigations reveal nothing until decades later when all three systems are found in the [[Omega Octant (SFU)|Omega Octant]].<ref name="SFUPD20Modern"/>

==Y179==
* [[Kumerian, Ardak (SFU)|Ardak Kumerian]] is re-promoted to [[Klingon Commodore (SFU)|commodore]], but in a staff position under the commander of the Western Fleet. While an average ship captain, he proves to be a genius at staff work, even if he hates the assignment.<ref name="SFUPD20Modern"/>
