Mirror Universe Timeline

=Background=
This takes place in one of the Mirror Universes, for just as the prime universe has potential alternates so does its “mirror”. Further is focuses on the timeline from a IUOP perspective.
=Pre-Terran Era=
==Roughly 197,590 BCE “High Noon”==
*In 2410, Second Terran Empire forces from the first timeline backed by Temporal Agents from the 29th century, send a vast assault fleet to destroy the Iconian homeworld in an effort to put an end the Mirror Universe's Iconian war in which the Second Terran Empire was on the losing end of the war.
*The Assault fleet proceeded to destroy the emergency escape gateway and proceed to glass Iconia, rendering it an airless rock. As such history records that the Iconians were rendered extinct, exterminated by some unknown alien invasion force that appeared from nowhere with technology superior to anything that existed at the time and after vanished never to be heard from again – becoming folklore merely known as the Demons of Fire and Shadow.
==Roughly 320 CE==
The Romulans depart Vulcan, fearing the growing theocratic atmosphere and increasingly violent culture, some of which also feared that their homeworld might destroy itself in nuclear war.
==Roughly 1400 CE==
Prior to the 15th century, the Vaadwaur Coalition discovered and charted the Underspace, using them to travel throughout the Delta Quadrant, as far as Talax and beyond. They used Underspace for trade, exploration and to monitor civilizations on the verge of interstellar travel. The Vaadwaur had a vast data-network of records of the Underspace, which they intended to share with other races after they felt they were ready to join the interstellar community - this data-network was largely destroyed when the Turei Hegemony invaded Vaadwaur territory and largely rendered the species extinct.
Eventually, the Turei and a dozen other slave species in a brutal campaign of extermination virtually wiped the Vaadwaur out of existance, even going so far as to render the Vaadwaur homeworld uninhabitable. They then claimed the Underspace for themselves and have been engaging in an ongoing galactic expansion ever since.
==1930 CE==
McCoy of the Prime Universe may have triggered the events for the mirror universes existence here by traveling through the Guardian from 2267 to 1930 and preventing Edith Keeler's death, leading to an Axis Victory. (The City on the Edge of Forever)
=First Imperium Era=
==Pre 2008 CE “Dark Age”==
*Lost Era, little is known about Terran history during this time period, it is known however that the Terran Empire is founded around 1930 based in the Americas. It will later encompass the entire world of Terra. At-least 4 world wars occurred.
==2063 CE==
*>!
* Following the first warp flight of Zephram Cochrane, a Vulcan scout ship seeking worlds for exploitable labor and personal slaves lands at Bozeman Montana. In an ironic twist Cochrane shoots the first Vulcan to appear from the ship before they can even have any real interaction, his staff proceed to kill the rest of the scout ship crew before they can send communication to Vulcan to send more vessels to begin conquest. They proceed to claim it's superior technology for themselves. It is this first strike that will eventually lead to the interstellar version of the Terran Empire.
==2064 CE==
The Terran Empire begins a crash starship building program using any weapons and shield tech it can beg, borrow, steal, or design. Many early First Contact missions are met with aggression. Terra's governing body declares that the age of isolationism is over and that an age of expansionism must take place to ensure that human civilization, not “Vile Xenoscum”, dominates the galaxy. 
==2066 to 2153 CE==
The Terran Empire conquers the Vulcans, Andorians, Tellarites, Denobulans, and the Orions.
==2153 CE “Terran - Romulan War”==
The So called Terran - Romulan War ended quite swiftly after the initial Terran invasion force was largely wiped out in the first engagement, Terran High command had extremely underestimated the Romulan Technocracies military capabilities which included but were not limited to missile weapons which seemed to completely disable a ships warp core. 
As such and with the growing rebellion problem back home an armistice was quickly signed creating a neutral zone between the Terran Empire and the Romulan Technocracy, with the Terran Empire agreeing to give up a small area of territory in concession.
==2154 CE==
By this time, the Terran Empire is at war with the 'Rebellion'. It is known that the Vulcans, Andorians and Orions were part of that rebellion. Denobulans were not.
==2155 CE==
Commander Johnathan Archer of the ISS Enterprise (an NX Class ship) mutinied against Captain Maximillian Forrest and siezed control of the ship. He then lead the Enterprise into Tholian space where, Archer's spies have informed him that the Tholians have captured an advanced Starship from an alternate reality and from the future.
That ship was the Constitution Class starship USS Defiant. Her crew were killed, and the tholians were dismantling the vessel for it's technology. The defiant had been lured into the mirror universe by the Tholians, who had created an Interphasic Rift between the two dimensions.
While Enterprise is destroyed, by the Tholians, Archer and a small crew manage to escape Tholian space using the Defiant's advanced weapons. Archer's plans to become Emperor are cut short, however, when he is poisoned by Hoshi Sato, who seizes the Defiant for herself and uses it to declare herself Empress.
Later that year, Hoshi Sato takes The Andorian Imperial Guard Shran as her consort, consolidating her power as Empress. However Shran betrays her and temporarily ceases the throne for himself as regent.
Hoshi Sato was sent to be in permanent exile on Deneva, but her transport was intercepted by Vulcan rebels. Hoshi Sato was able to strike a deal with one of the rebels, and her former Enterprise crewmate, T'Pol. By helping her escape the rebels and helping reclaim the Empire from Shran's Andorian forces, the Vulcans were then raised to a status equal to that of Terrans.
==2156 CE==
Arik Soong is assassinated. This leads to a delay in the development in artificial intelligence until much later than when it occurs in the Prime Universe.
The Romulan Technocracy and Terran Empire enter into a non-aggression pact as the Empire focuses on regaining stability after finally crushing the rebellion and begin focus on the growing threats of the Cardassian State and Klingon Empire.

==2284 to 2288 CE==
Emperor Spock initiates sweeping reforms which begins to convert the empire into a republic. he conscripts doctors Carol and David Marcus to help him eventually form Memory Omega, which will be the storehouse of all Terran Knowledge and accomplishments after it's fall and to assist in the building of a successor state which will hopefully have learned from the past empire's mistakes.
Spock begins laying the groundwork for his long term elements of his plan. He recruits many Vulcans and begins to downgrade the Empire's defenses.

==2294 CE==

==2295 CE==
After the reforms the newly formed Terran Republic was militarily weak, and was unable to deal with the recently formed Klingon-Cardassian Alliance, whom were far more destructive and malicious than even the Terran Empire at its height. When the KCA finally reached the core worlds they Glassed half of Vulcan, meanwhile the Romulan Technocracy gave the Terran Republic details on the KCA invasion plans, including that the KCA were going to do "worse than Vulcan to Terra". This act saved at least a couple billion terrans (whom escaped to outlying sectors far from the reach of the KCA at the time), though despite such the KCA assault force was able to breach the Sol System defences and proceeded to bombard Terra until the oceans boiled away and the atmosphere was blasted away. The Estimated death toll was at-least 5 Billion, with some estimates as high as 9 billion.
Spock is killed in the attack on Terra. Terrans are largely reduced to Slave status (or less) across known space. 
Several Vulcans now serve as sleeper agents within the Alliance, among them are Saavik and Tuvok. They maintain plot to build the path to a new empire from within. The nexus of that goal is the secret Memory Omega facility where many key personnel have been placed without the KCA's knowledge.

They are attempting to protect the last few betazoids and to prevent the extermination of their species.
