This timeline mainly focuses on events from an Imperial point of view, and is therefore not definite for non-Cyrodiil affairs.
Middle Merethic Era
(c. ME 2000)
- The Niben valley and its environs are inhabited by numerous human tribes: the Nedes, Kothringi, Al-Gemha, Keptu, Men-of-Ge, Al-Hared, Men-of-Ket, Orma, Yespest, Horwalli, and many others. Later generations will remember them as "Nedes", though this was the name of but one of many tribes.
- Likewise, the areas later known as the Gold Coast and Hammerfell are inhabited by human tribes, though these are culturally distinct from the Niben ones.
(c. ME 2000 - 1500)
- The Aldmeri explorer Topal (or Torval) the Pilot sets sail from the Summerset Isles, looking for the mythical continent of Aldmeris. He is the first Elf to explore the shorelines of Tamriel and interact with its native populations. Topal explores the course of the river Niben up to Lake Rumare, reporting the existence of Khajiit, Argonians, and a mysterious race of "Bird-people" inhabiting the future site of the Imperial City. He claims these people give him their islands as a gift in return for the art of literacy. Topal's account suffers from several anachronisms, and may be a forgery meant to justify the later Ayleid land-grab in this area.
- Various Aldmeri factions colonize the coastline of Tamriel. Presumed birth of the Bosmer, Khajiit, Falmer, and Dwemer civilizations.
- Founding of the first Ayleid city-states in the Cyrodiilic Heartland. These Elves were dissenters from the Aldmeri mage caste, fleeing their home culture's restrictions on Daedra worship and the usage of Dawn Magics. Unlike other Elven colonists, the first Ayleid settled deep in the Heartland, subjugating and enslaving the indigenous population through use of their summoned Daedra armies. The Ayleid city-states are tribute-kingdoms to the throne of Alinor, though the vast distances make enforcing Summerset law all but impossible.
- Several enterprising Elven families explore an colonize the northwest of Tamriel, without relinquishing their ties to Alinor. First among them are the Direnni clans.
- Small groups of Atmoran colonists settle the northern shores of Tamriel, fleeing war, hunger, and ill-defined political struggles in their homeland. This slow immigration movement continues for the next hundred years.
- Construction of White-Gold Tower, known as the Temple of the Ancestors or the Citadel to the Ayleid. This magical construction, erected through the knowledge of the Dawn Magics, amplified the power of the Ayleid sorceror-kings and allowed them a measure of control over the fabric of reality, similar to that of the Ada-Mantia Tower in Balfiera and Crystal-Like-Law in Summerset.
- The Ayleid Hegemony expands to the east and west, founding city-states and fortresses in modern-day Colovia, southern Nibenay, and Argonia.
- Saint Veloth, an Aldmeri prophet and mystic, proclaims the faith in the Good Daedra. Rejecting the decadence of Summerset culture, he leads a mass migration of the faithful Chimer into the promised land of Resdayn, later known as Morrowind.
- The colony of Saarthal is founded in northern Skyrim, being the first large-scale Nordic settlement on Tamriel.
Late Merethic Era
(c. ME 1000 - ME 800)

- The Nords finish their conquest of modern-day Skyrim. The Falmer, driven to extinction, disappear from recorded history.
- Tension and small-scale skirmishes occur between the Nordic Empire and the surrounding Elven realms: the Direnni, Velothi, and the Ayleid sphere of influence.
c. 1E 198
- The Narfinsel Schism: the southern Barsaebic city-states of the Ayleid hegemony chafe under the cultural and political dominance of the High Heartland Monarchs. The Barsaebics are conservatives who maintain strong connections with Alinor and Direnni. They are concerned over the Heartland's reliance on Daedric pacts, neglect of the Aedra, abuse of the Dawn Magics, and general deviation from mainstream Aldmer culture.
- The Scouring of Wendelbek: the Barsaebics are defeated by an alliance of Daedrophile Ayleids led by Glenferen of Atatar.
- The surviving barsaebics take refuge in their remote colonies in southern Blackwood and the Argonian borderlands.

- Worship of the Eight Divines and the Ancestor Moth Cult, responsible for studying the Elder Scrolls, are founded. Both harken back to Ayleid predecessors.
- The new Alessian state becomes a protectorate of the Nordic Old Empire. Several northern holdings in the area of modern-day Artemon, Bruma, and Cheydinhal are under direct Nordic rule.
1E 243-1E 498
- Alessian power slowly grows and consolidates. Imperial culture develops from joint Nedic, Nordic and Elven traditions.
- As a reward for their aid in battle (and to keep the unruly mercenary armies at arm's length), Alessia grants the Nordic chieftains land claims in what is now known as Colovia. The Nords quickly form several war-parties and, aided by tribeless Nedic serfs, wage a campaign of conquest against the remaining Ayleid enclaves of the west.

- Belharza the Man-Bull assumes the throne.
c. 1E 266-1E 358
- Nedic and Nordic settlers migrate to Colovia, taking land from local Ayleid city-states and Nedic settlements. The first Colovian Estates are founded, vassals to the Alessian throne. Known Estates are the Strident Coast, Skingrad, Sarchal, Chorrol, Bruma, and Falkreath.
- The War of the Tribes: political disagreements between the Nedic tribes lead to a small civil war in the east and south of the Nibenay. The conflict is exploited by the central Niben-Nedic administrators loyal to the Emperor in order to destabilize the tribelands. Following the war, the rural tribes are weakened and the central temple administration grows in importance.

- Bendu Olo forges defense pacts and trade treaties with Hammerfell and the nations of the Iliac Bay. For the first time, the Colovian Estates develop strong diplomatic relations with nations beyond the Alessian Empire.
- The military success of Bendu Olo leads to the founding of the Oloman Compact or Oloman Confederacy, a short-lived movement of unity among the Colovians. The Compact stipulates that the Estates will aid each other when threatened by war, and normalizes defense treaties and alliances with the other human kingdoms.
- In contrast to the Colovian Estates, the Alessian Empire is declining. The densely populated cities of the Nibenay are hard-hit by plague and famine.

Slowly, the old royal houses morph into prestigious officer families, supplying the Imperial Legions and Navy with their upper ranks, and taking control over the conquered provinces as governors.
- The Niben Battlemage-Hierophants ingratiate themselves as the court of Reman, introducing Nibenese decadence to the latest wave of western warlords to control the Empire. In time, the Hierophants join their bloodlines with the Dragonguard Tsaesci from Akavir, determined to gain both social standing and control over the arcane secrets of the far east.
- Influenced by Akaviri ideas of governance, the Reman Emperors reform their bureaucracy to be more efficient and rational. The result is the Imperial Curia, an order of magistrates whose nobility arises from merit, not birth (at first). The Curia quickly comes to control key aspects of the Imperial government.

- Katariah dies in an bandit ambush in Black Marsh, later discovered to be the work of a disenfranchised branch of the Septim family. She is succeeded by Cassynder.
- Emperor Cassynder suffers from poor health, possibly due to his half-Elven heritage. He does not have the strenght to govern his kingdom properly, and leaves much work to his half-brother, Uriel Lariat.
