The Fourth Era -- Death Knell of the Empire
- 4E 0 End of the Oblivion Crisis.
- The banishing of Mehrunes Dagon from Tamriel by the Champion of Cyrodiil, Martin Septim, and the avatar of Akatosh ends the Oblivion Crisis. The Septim bloodline ends and the Amulet of Kings is destroyed. The Third Era ends, marking the beginning of the Fourth.
- The Fourth Era begins with no Emperor on the throne of Tamriel. High Chancellor Ocato, the Elder Council, and the Blades try to maintain order. The provinces start to take advantage of the Empire's weakened state.
- 4E 5 The Red Year. Red Mountain erupts; Vvardenfell is devastated by natural disasters.
- 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.
- 4E 510 The Empire begins to collapse. Black Marsh secedes from the Empire after the explosion of Red Mountain; it is soon followed by Elsweyr.

The Rise of the Aldmeri Dominion and the Decline of the Empire
- 4E 22 The Thalmor seize total control of Summerset Isle and rename it Alinor.
- 4E 23 Annaοg Hoοnart 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 comes about after a Thalmor-backed coup overthrows Valenwood's government. The Empire and its Bosmer allies in the Imperial-backed government are caught off-guard and defeated by better-prepared Bosmer and Thalmor troops following the coup.
- The Dominion severs all contact with the Empire and is silent for the next 70 years. Most Imperial scholars believe that there was some sort of internal strife in Alinor during this period.
- 4E 40 Umbriel, a floating city, appears on the coast of Black Marsh, heading toward Morrowind.
- 4E 42 The Night of Green Fire occurs in Sentinel.
- Altmer dissidents who had fled to Sentinel from the Thalmor in Summerset Isle are attacked by Thalmor operatives. Their efforts to fight back against the Thalmor are in vain, and by the time Imperial Legion soldiers arrive, the entire refugee district of the city had been destroyed. The event became known as "The Night of Green Fire" due to the destructive magic attacks employed by both sides during the battle.
- 4E 50 The Keepers of the Razor first appear in Imperial records.
- 4E 65 Brara Morvayn, ruler of Solstheim, passes away and is replaced by her son Lleril.
- 4E 95 An unsuccessful attempt is made on the life of Lleril Morvayn as part of a plot masterminded by House Hlaalu to take control of Solstheim from House Redoran.
- 4E 98 The two moons of NirnMasser and Secundavanish for two years in what becomes known as the Void Nights.
- 4E ~100 Artaeum disappears.

- 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 during an event known as the Great Collapse.
- The citizens blame the College of Winterhold due to its remaining unscathed when everything around it falls into the Sea of Ghosts. The College denies this, theorizing that the collapse is tied to the destruction of Vivec and eruption of the Red Mountain.
- 4E 129 Riften is razed during an uprising against its Jarl.
- Hosgunn Crossed-Daggers controversially ascended to Riften's throne in 4E 98 and instituted harsh taxes for his personal benefit. The citizens rebel and burn Hosgunn's castle to the ground with him inside, but the fire spreads to the rest of the city. Riften is rebuilt over the next five years, but remains little more than a "glorified fortress" of "wooden structures and rough stonework" compared to the sprawling city of old.
- 4E 130 Lleril Morvayn uses his personal wealth to repair the Bulwark, a barricade which protects Raven Rock from ash storms.
- 4E 150 A small force of Argonians land on the island of Solstheim bent on destruction, but Lleril Morvayn repels them.
The Great War and Its Aftermath
- 4E 168 Emperor Titus Mede II ascends to the throne.
- The Empire is now a shadow of its former glory. Valenwood and Elsweyr have been ceded to the Thalmor, Black Marsh has been lost to Imperial rule since the Oblivion Crisis, Morrowind has yet to fully recover from the eruption of Red Mountain, and Hammerfell is plagued by infighting between the Crown and Forebear factions. Only High Rock, Cyrodiil, and Skyrim remain 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 174 The Reachmen rebel, taking over the Reach.
- With the Empire busy fighting the Thalmor, Markarth is left undefended. The Reachmen take the opportunity to overthrow the Nords of the Reach, retaking The Reach easily. The changeover is relatively peaceful, with only a few of the harshest Nord landowners being put to death.
- 4E 175 The Battle of the Red Ring results in the complete destruction of the main Aldmeri force 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 Elder Scrolls mysteriously disappear from the Imperial Library.
- The Elder Scrolls are scattered across Tamriel by forces unknown. Members of the Cult of the Ancestor Moth set out to search for them.
- 4E 175 The Great War ends with the White-Gold Concordat.
- The peace treaty between the Empire and the Aldmeri Dominion gives the Thalmor free rein to stamp out the worship of Talos throughout the Empire, and cedes 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.
Ulfric Stormcloak and the Seeds of Civil War in Skyrim
- 4E 176 Ulfric Stormcloak retakes The Reach, instigating the Markarth Incident.
- The Empire and the son of the deposed Jarl promise Ulfric Stormcloak free worship of Talos in exchange for retaking The Reach. Ulfric forms a Nord militia and crushes the Reachmen at Markarth with the aid of the thu'um. The survivors flee into the wilds, forming a group called the Forsworn. Ulfric is arrested when the Thalmor discover the open worship of Talos. Ulfric and his men are eventually released, but the incident kindles what will become the Stormcloak Rebellion.
- 4E 180 The Second Treaty of Stros M'Kai is signed.
- Having been fought to a standstill by the Redguards, the Aldmeri Dominion withdraws from Hammerfell.
- 4E 181 The ebony mines of Raven Rock are completely exhausted, and the colony turns to hunting and fishing for sustenance.
- 4E 188 Wayrest falls to corsairs.
- Corsairs seize Wayrest and raid the Dark Brotherhood sanctuary there, destroying it.
- 4E 188 Bravil erupts into violence.
- A war of control being waged by Cyrodiil's two largest skooma traffickers leads to violent fighting within the city. The Lucky Old Lady statue is destroyed in the fighting. The Night Mother's crypt is raided and Alisanne Dupre, Listener of the Dark Brotherhood, is killed defending it. The Night Mother's remains would later come into the care of Cicero.
- 4E 201 Torygg, the High King of Skyrim, is killed by Ulfric Stormcloak in Solitude.
- 4E 201 The Nords of Skyrim engage in a civil war.
- The people of Skyrim become divided between the Stormcloaks, led by Jarl Ulfric Stormcloak of Windhelm, and the Imperial Legion, commanded by military governor General Tullius. The Stormcloaks believe their Nord way of life is at risk, while the Imperials believe Skyrim is a part of the Empire, and must follow its laws and customs.
- 4E 201 Alduin the World-Eater destroys the town of Helgen, heralding the return of the dragons and the end of the world.
