This title of Emperor is the name of a ruler of a specific Empire. The title has been applied to the rulers of the Ysgramor Dynasty, the Reman Dynasty, the Septim Dynasty, and the Mede Dynasty. The Emperor is the Head of State for the entire Empire. The Emperor resides in the Imperial Palace in the Imperial City. With the title inherited through blood by the first-born male child of the current emperor, the title has been bestowed upon daughters and dowagers. Until the reign of Tiber Septim, the title was passed through lineage. With no surviving heirs, Septim was granted the title due to his war prowess. After the death of the last-known Septim heir at the end of the Oblivion Crisis, Martin Septim, the Elder Council struggled to declare and emperor, until Titus Mede I seized the Ruby Throne;thus began the Mede Dynasty.
Since the rule of Slave-Queen Alessia, the Amulet of Kings has traditionally been a symbol of the Emperor's power, with the Aedric relic being the means by which the ceremonial Dragonfires were lit within Temple of the One, at the Emperor's seat of power, the Imperial City. This tradition has been abandoned since the Oblivion Crisis was stopped by Martin Septim.
Emperors ascend to the throne through bloodlines. The title is usually handed from father to son, upon the death of the former. The title has been handed to dowagers of Emperors, most notably Katariah. In the absence of an heir, the Empires successions were different, during the time of the Second Empire the Akaviri Potentate ruled in the Emperors stead.During the Third Empire the Elder Council elected a Potentate to rule in the Emperor's place until a suitable alternative can be crowned. 
The Amulet of KingsEdit
When Saint Alessia rallied the slaves against the Ayleids, Akatosh bestowed upon her the gem that would later be faceted into the Amulet of Kings. The jewel later became crucial in the crowning of Cyrodilic Emperors.
During the Septim Dynasty, newly crowned Emperors brought the amulet to the Temple of the One to light the Dragonfires and keep the barrier between Tamriel and Oblivion shut. Martin Septim, an illegitimate heir, broke the tradition when he destroyed the amulet to invoke Akatosh and return Mehrunes Dagon to Oblivion, thus sealing the barrier between Oblivion and Tamriel forever.
The First EraEdit
The Ysgramor DynastyEdit
The origins of the first Empire of the Nords date back to the late Merethic Era when Ysgramor and his sons escaped the slaughter of the first human city of Saarthal by the native elves. He returned to Skyrim with an army known as the Five Hundred Companions and lead a reprisal campaign against the elvish population. The city of Saarthal was retaken and eventually rebuilt. Ysgramor then ordered the construction of Windhelm which would serve as the capital of the Empire.
In the following years, Ysgramor and his army hunted the remaining elves to near extinction. Once Skyrim had been purged of Snow Elves, the ancient Nords turned their attention to Solstheim where a great number of skirmishes were said to have taken place.
The Alessian EmpireEdit
The first Imperial Empire of Tamriel began with Queen Alessia. The Alessian Empire often called the "First Empire", was founded by Alessia after the overthrow of the Ayleid by the human slaves on Cyrodiil. Outside of historical writings, the term more specifically refers to the Empire as it exists since the unification of Tamriel under Tiber Septim, Emperor of Cyrodiil at the end of the Second Era.
The Reman EmpireEdit
The birth of the Reman Empire is shrouded in myth. It is believed that in the first Interregnum, many lords and warlords fought for the throne, while others searched and prayed to Saint Alessia for the return of the peace brought with the first empire. Hrol, king of what is now known as Old Hroldan, specifically went searching for the spirit of Alessia. He had a vision of her standing with Akatosh, and was seduced by the spirit of Alessia. Hrol is believed to have "" in the belief it was Alessia.
Nine months later, the Hill birthed Reman Cyrodiil, who even as an infant spoke with the voice of an Adult. He marched into The Imperial City and was proclaimed a divine emperor. Reman managed to unite the Empire's claims of Skyrim, High Rock, Hammerfell, Nibenay, and Colovia by repelling Akaviri invaders at Pale Pass. Elsweyr and Valenwood were taken militarily in the next decade or so. Morrowind never joined the Empire because, as the war between them was concluding, Reman Cyrodiil III and his son were both assassinated by the Dark Brotherhood.
The Reman Empire fell twice. First it fell at its peak, with the assassination of all Reman Cyrodiil's heirs. This lead to the slow decline of the empire under the Akaviri potentate, Versidue Shaie. In 2E 324, the potentate was assassinated by the Morag Tong and his son, Savirien Chorak, took power. The new potentate and all his heirs were assassinated in the years to come by the Dark Brotherhood, ending the empire.
The Second and Third EraEdit
The Septim EmpireEdit
The Potentate Versidue Shaie ruled for 430 years in prosperity that established some traditions of the empire before the last Potentate was assassinated by Morrowind's official assassins guild, the Morag Tong. His successor, also a Tsaesci, was promptly murdered by the Dark Brotherhood, leaving no Akaviri heirs, and officially ending the Second Empire.
A series of non-noteworthy Emperors would follow over the next four hundred years, until the rise to prominence of the Imperial General Talos Stormcrown, also known as Tiber Septim. Septim commanded the army and navy of Cyrodiil through a number of victories or stalemates, slowly bringing the independent states of Tamriel under the umbrella of Imperial Provinces. Talos' own emperor was assassinated in 2E 854, leaving the Elder Council in charge of the government and, effectively, putting Tiber Septim in charge of the Empire. He continued to press his attacks across Tamriel, until in 2E 896, he enacts a truce between Cyrodiil and Morrowind to bring the Dunmer province into the Empire as a mostly independent province, in return for the aid of the golem Numidium in defeating the rest of the continent. Talos succeeds, and is named Emperor Tiber Septim I, beginning both the Third Era and the Third Empire, the Septim Empire.
During his time as Emperor, Tiber Septim had an affair with a Dunmeri queen named Barenziah. Outraged by the pregnancy, he ordered the child aborted. Barenziah fled the province. In a memoir, she recounted that, to avoid scandal, the child was named the daughter of an enigmatic bard, Nightingale. The daughter, Dralsi Indoril, bore one daughter, Karliah. This daughter, now a native of Skyrim, may have been the only legitimate Septim heir following into the Fourth Era.
The first few in the line of Septim Emperors ruled with relative peace and prosperity, but within 50 years, mismanagement and political infighting become the norm. In more than one case, wars are fought over the throne, including the notable War of the Red Diamond, fought among three surviving heirs. Potential kings or queens frequently attack the sitting Emperor, or have him assassinated, and the Empire begins to lose its grip on several provinces. It would not be until the reign of Uriel Septim V that the lands of Tamriel were reconquered and the Empire returned to its place of power. Unfortunately, Uriel V also chose to launch an ill-planned invasion of Akavir, in which he was defeated soundly and killed.
The next generations of Septim rule restored the peace, prosperity, and most importantly, the stability of the Imperial line to Cyrodiil. By the time of Pelagius IV and his son, Uriel VII, the Empire was back almost to the height of its power.
Uriel VII's reign was overall a stable one, but was dotted with occasional strife and near-catastrophe. His Imperial Battlemage Jagar Tharn, possibly at the urging of Mehrunes Dagon, imprisoned him and ruled in his stead for several years. The Emperor escaped just in time to thwart an attempt by the King of Wayrest to conquer Daggerfall. By the time of the Dagoth Ur crisis in Morrowind, there was talk of the failing health of the Emperor, and concerns over the future of the Empire.
As it turned out, the Emperor's health was not an issue, but he was assassinated trying to flee the Imperial City after learning of the murder of every known heir to the throne. Their murderers, a cult called the Mythic Dawn, serving Mehrunes Dagon, were preparing Tamriel for an invasion by the Daedric Lord. Septim's one remaining illegitimate son Martin eventually led a defense of the Empire by becoming an avatar of Akatosh and defeating Dagon, but died in the process.
The Empire was left without an heir once more, but this time, with no one even distantly related to Tiber Septim available to be crowned. The Elder Council, which had essentially ruled during the periods of the weakest emperors, was now officially running the Empire. Many provinces floated rumors of dissolving the Empire; after the Oblivion Crisis many provinces left the empire like Black Marsh.
The Fourth EraEdit
After the death of the last Septim, the Elder Council struggled to maintain peace in Cyrodiil, placing new Emperors on the throne -- none of which were well-taken by the people of the Empire. Eventually a Colovian warlord named Titus Mede conquered the Imperial City with just a thousand men and crowned himself Emperor. Thus began the Mede Dynasty.
Following the death of Titus Mede II, the Council could not successfully coronate another emperor.
As a descendent of Queen Barenziah, a thief in Skyrim named Karliah might be the only legitimate hier to the Cyrodilic throne. Dralsi Indoril, her mother, may have been the illegitimate child of Tiber Septim, in turn making Karliah a possible Septim and giving her a claim to the throne as Empress.

- When Republican Rome (the Empire on which this Empire is based) turned into a de facto monarchy in the second half of the 1st century BC, at first there was no name for the title of the new type of monarch. Ancient Romans abhorred the name Rex ("king"), and it was critical to the political order to maintain the forms and pretenses of republican rule.
