crisis of the third century

In 251, after killing the Roman emperor in battle and winning a decisive victory at abritus, king Cniva teams up with Priscus to establish an independent state in Thrace, Dacia, and possibly Moesia, where goths, vandals, and other tribes across the Danube could settle. How would this new...

Before I get into the details of the question, let me set out the scenario. At some point in the 3rd Century, Persia converts to Christianity in a "Light shines East" style scenario, where Christianity is largely merged with Zoroastrianism and Ahura Mazda is conflated with the Christian God. The...

challenge is to get germania unified by 200 AD from rhine to don rivers, from franks to goths edit : POD must be after Teutoburg forest but unification must be complete by 3ard century and it must coexist with Roman empire of atleast 395 borders

Macrinus become Emperor in 217 and unfortunately had a very short reign. His goal seems to have been a return to Septimius Severus-era policies and he was left in a difficult situation due to Caracalla's reign. When one takes into account his humble origins, he comes across a compotent...

By 1006 AUC, the Military Anarchy was in full swing. Trebonianus Gallus and his son Volusianus had been co-emperors for two years. Their reign had not been an easy one. Not only were Goths attacking along the Danube and Asia Minor, but the Persians had also invaded in the east, capturing Antioch...

A/N: Hello all! I am back with another new TL! This will be replacing Shadow of the Lost Son for the time being, as I currently do not have any interest to continue it. This will follow the story of Aurelian, as he continues to stabilise the empire after the Crisis of the Third Century. What...

a question that is some times asked is why the Han dynasty collapsed while the roman empire surived the third century crisis ( so since i could find any thing) i ask can we reverse it have the roman empire collapse or split in the third century ( or should i say mantain the split of the ot with...

Could a roman prophet theoretically emerge in the late roman empire and unite one of the roman pagan cults or deities ? Maybe comparable to a Jesus figure or Mohammed but based in pagan roman believes/culture ? Or would that be ASB/impossible ?

As we all know, the greatest emperor Aurelian would reign for 20 glorious years, singlehandly ending all threats to Rome and bringing about a new golden age to The Roman Empire. But what if his reign was ended early? What if Aurelian was assassinated? Would Roman have been able to surpass the...

What if the Roman Empire had collapsed during the Crisis of the Third Century?

---------------------- Part 1: Known Unknown One of the most frustrating but important battles to study by far is the Battle of Resaena, which took place in what was then Roman Syria in 243. Other than the fact that Roman and Persian arms clashed with great ferocity when the event took place...

Aurelian and what he might have accomplished had he lived longer is a frequent topic among counterfactual historians, but I believe his predecessor is also worthy of attention. Claudius Gothicus, despite reigning for less than two years, proved an able military commander, crushing a Gothic...

What if Tetricus had managed to win the Battle of Châlons? Could it have saved the Gallic Empire?

What if the Crisis of the Third Century hadn't happened? How might things be altered?

What if Aurelian had died before he could become emperor? What impact would it have had on the Crisis of the Third Century? Could it result in the end of the Roman Empire?

Which of Diocletian's reforms were good or necessary or beneficial? Which were harmful? What additional stuff would you change or not change were you emperor around this period, trying to rectify the problems of the Principate that led to the 3rd century crisis?

So, assume that the Roman "barracks emperors" are even less competent at defending the empire from the Germanics, Persians, and other usurpers, and the whole thing collapses into multiple squabbling states sometime around the 270's AD. One of the Germanic tribes, led by their king, estabilishes...

Was it possible that the Sassanids could have conquered the Roman East the same way they did (temporarily) in the 7th century by exploiting the civil war?They were able to wipe out Valerian’s army,but were ultimately defeated by Odenathus,but could they have gone further?

What if, say, emperor Diocletian had less sons or even just one, affecting his tetrarchy plan and diminishing the ammount of portions within the empire, specifically two? How much of a difference would it make? IMO, because the empire was divided in four, it ended up in chaos until it could be...

The roman emperor Carus (born 222 AD, died 283 AD) was mostly known for a handful of achievements, such as subjugating the sarmatians coming across the Danube and founding a short-lived dynasty that was eventually overthrown by the famous Diocletian. On the time of his death at age 61, Carus was...
