Okay, so here's everything that has happened between Oblivion and now, or what is commonly referred to as the "Fourth Era", from:
http://www.uesp.net/wiki/Lore:History
_________________________________________________________________________________________
First Century
4E 0 — End of the
Oblivion Crisis.
4E 1 — The Empire begins to collapse.
- Black Marsh secedes from the Empire a few years after the proclamation of the new era; it is soon followed by Elsweyr.
4E 10 — Potentate Ocato is assassinated by Thalmor agents, initiating the Stormcrown Interregnum.
- For the next seven years, the Elder Council is fractured by petty infighting over the Ruby Throne, further weakening Imperial power in the provinces.
4E 17 —
Titus Mede, a Colovian warlord, captures the Imperial City and is crowned the new emperor of the Empire of Tamriel.
4E 18 —
Prince Attrebus Mede is born.
4E 22 — The
Thalmor seize control of
Summerset Isle and rename it Alinor.
4E 23 —
Annaïg Hoïnart is born.
4E 29 — The
Aldmeri Dominion is recreated after Alinor and
Valenwood proclaim a union, and all contact is severed with the
Empire.
- The union came about after a Thalmor-backed coup overthrew Valenwood's government. The Empire and its Bosmer allies are caught off-guard and defeated by Altmer forces that invaded Valenwood following the coup.
4E 40s —
Umbriel, a floating city, appears on the coast of
Black Marsh, heading toward
Morrowind.
4E 40s —
Red Mountain erupts;
Vvardenfell is destroyed.
- In Vivec's absence, the Ministry of Truth becomes unstable. Vuhon creates an Ingenium that uses at first dozens of dying souls, then a small number of living ones to stabilize the rock. The soul of Sul's wife Ilzheven was among them. In a fight to free her, the Ingenium is destroyed and the rock crashes into the city of Vivec with all the energy it originally had. The impact causes Red Mountain to erupt and destroys the entire island of Vvardenfell, as well as causing massive destruction to the rest of the province.
- The Argonians invade southern Morrowind after the eruption of Red Mountain.
4E 98 — The two moons of
Nirn,
Masser and
Secunda, vanish for two years in what becomes known as the Void Nights.
4E 98 — The Dark Brotherhood Sanctuary in Cheydinhal is raided by Imperial Forces. The previous Listener is supposedly killed in the attack.
[edit] Second Century
4E 100 — The Void Nights end, with the Thalmor taking credit for the return of Nirn's moons.
- The Khajiit credit the Thalmor as their saviors and Imperial influence in Elsweyr begins to wane dramatically.
4E 115 — The Elsweyr Confederacy becomes the two kingdoms of Anequina and Pelletine, which the Aldmeri Dominion accepts as client states.
4E 122 — Most of
Winterhold collapses into the sea. The citizens have blamed the
College of Winterhold but the College denies it.
4E 168 — Emperor Titus Mede II ascends to the throne.
- The Empire is now a shadow of its former glory. Valenwood and Elsweyr had been ceded to the Thalmor, Black Marsh had been lost to Imperial rule since the Oblivion Crisis, Morrowind had yet to fully recover from the eruption of Red Mountain, and Hammerfell was plagued by infighting between the Crown and Forbear factions. Only High Rock, Cyrodiil, and Skyrim remained prosperous and peaceful.
4E 171 — The
Great War begins with armies from the
Aldmeri Dominion invading the Imperial provinces of Hammerfell and Cyrodiil.
- After Titus II rejects an ultimatum to make massive concessions to the Thalmor, Aldmeri armies invade. An army led by Thalmor general Lord Naarifin emerges from hidden camps in northern Elsweyr and assaults southern Cyrodiil, flanking Imperial defenses along the Valenwood border. Leyawiin falls to the invaders, and Bravil is surrounded and besieged. Simultaneously, an army under Lady Arannelya crosses western Cyrodiil, bypassing Anvil and Kvatch and entering Hammerfell. This army is joined by smaller forces landing on Hammerfell's coast. Imperial troops are forced into retreat across the Alik'r Desert.
4E 174 — The Imperial City is sacked by Aldmeri forces.
- Titus II flees north from the city, smashing through the surrounding Aldmeri forces with his main army and linking up with reinforcements heading south from Skyrim under General Jonna. The Imperial City falls to the invaders. The Imperial Palace is burned, White-Gold Tower is looted, and the Aldmeri commit many atrocities against the defenseless populace.
4E 175 — The Battle of the Red Ring results in the complete destruction of the Aldmeri army in Cyrodiil, a victory for the Empire precipitating the end of the Great War.
- The Imperial City is retaken and Titus II's decision to withdraw from it the previous year is vindicated. Despite this resounding victory, however, the Empire is exhausted and unable to continue the war. Realizing this, Titus II seeks to negotiate with the Aldmeri Dominion to end the war.
4E 175 — The
Great War ends with the
White-Gold Concordat.
- The Concordat is a peace treaty between the Empire and the Aldmeri Dominion. The terms of treaty gave the Thalmor free rein to stamp out the worship of Talos throughout the Empire, and ceded a large section of southern Hammerfell. Critics note that these terms are almost identical to the ultimatum that Titus II rejected at the start of the war.
4E 175 —
Hammerfell leaves the Empire after rejecting the White-Gold Concordat.
- Titus II renounces Hammerfell as a province of the Empire to preserve the treaty after the Redguards oppose ceding their lands. The Redguards see this as a betrayal, and a lasting bitterness between Hammerfell and the Empire is sown to the delight of the Thalmor. Hammerfell continues to war with the Aldmeri Dominion for the next five years.
4E 180 — The Second Treaty of Stros M'Kai is signed.
- Having been fought to a standstill by the Redguards, the Aldmeri Dominion completely withdraws from Hammerfell.
[edit] Third Century
4E 201 — Torygg, the High King of
Skyrim, is killed by
Ulfric Stormcloak at
Solitude.
4E 201 — The
Nords of Skyrim engage in a civil war.
4E 201 —
Alduin the World-Eater makes the first strike on the small town Helgen, symbolizing the return of the
dragons and the end of the world.
_________________________________________________________________________________________
Note that the Khajit have recognized the Thalmor (Aldmeri Dominion) as their saviors, and have become client states of the Thalmor. They don't appear to want to be "saved" by the Empire. Black Marsh seceded of it's own accord, as an independent nation.
