Early Years Era (SFU)

Tactical Warp EraSFU ChronologyMain Era

2479 to 2519

2479

Y79

• The Tholians arrive in the Milky Way galaxy. Although the region had been explored and claimed by the Klingons a few years earlier, no Klingon ships were present at the time, so the Tholians remained undetected.
• The Federation launches the first of the Republic class cruisers and begins refitting the older Province class cruisers with tactical warp drive.

2480

Y80

• At this time, most empires have developed tractor beams that can function in a 360° arc.

2482

Y82

• The First Klingon-Kzinti War ends, with the Klingons capturing three key planets.

2483

Y83

• The Tholians make first contact with the Klingons and establish the borders of the Holdfast, sparking the first of several vicious border wars, which lasts for two years. The Klingons suffer heavy losses, and the Tholians wipe out three Klingon colonies, the largest of which, Kalesta, was intended as a jumping-off point for a conquest of the Romulans.
• Federation Marine Major General Kripney delivers the famous report, "Case for Primary Contact Action Teams in Novel Contact Environments" to Star Fleet Command.

2484

Y84

• Having defeated the Kzinti, the Klingons attack the Hydrans, sparking the Second Hydran-Klingon War, which the Klingons refer to as the War of Retribution, and the Hydrans call the War of Infamy.
• The Lyrans attack the collapsing Hydran border, sparking the Third Hydran-Lyran War, taking advantage of the weakening of the Hydran defenses in the wake of the Klingons' attacks.
• The Tholians make first contact with the Federation.
• In the Federation, Tumball Massi is placed in charge of the Primary Contact program; this is the gensis of the later Prime Teams.

2485

Y85

• First contact occurs between the Klingon Empire and the United Federation of Planets, although the Federation worlds were aware of the Klingons due to earlier encounters by the Vulcans. The Klingons — already embroiled in a war with the Hydrans, a border conflict with the Tholians, and watching the Kzinti border for renewed hostilities — decide not to provoke this new adversary, but instead send Klingon civilians and diplomats to hold trade negotiations and discuss cooperation treaties. The initial friendly terms last for several years, but become increasingly strained as both sides establish colonies in strategic locations in the relatively unexplored territory between the two powers.
• The Gorn successfully blockade the Paravian homeworld, destroying all orbital and space-related facilities, and begin hunting down all surviving Paravian ships. Some Paravians escape to the Omega Octant. The Gorn are unwilling to annex the Paravian territory, however, and instead set up a Trusteeship Zone; in theory, this territory will be returned to the Paravians once they agree to peacefully coexist.

2487

Y87

• Klingon forces destroy the Hydran fleet and colonies, committing many atrocities in the process. All Hydran ships larger than police corvettes are destroyed, and the Hydran Kingom is reduced to a Klingon client state. The Klingons establish governors over Hydran planets, but due to the difference in atmospheres, they are restricted to orbiting satellite bases and never able to effectively control the populace directly.
