The History Of Rome

Immediatly after becoming the undisputed Emperor in 285, Diocletian elevated Maximian to serve as his Imperial colleague.

The Crisis of the Third Century finally ended with the mini dynasty of Carus and his two sons. In 284 Diocletian rose to power, ushering in a new age in Roman history.

After Aurelian's death, an old Senator named Marcus Cluadius Tacitus briefly reigned before the throne fell to Probus, who ruled from 276-282.

Aurelian defeated the breakaway western provinces and reunified the Empire in 274 AD. The next year he was assassinated by officers who had been tricked into committing murder.

In 272 Aurelian finally managed to bring the east back under Roman control by defeating Queen Zenobia of Palmyra.

Aurelian became Emperor in 270 and immediatly faced an invasion of Italy by the Juthungi. After succesfully driving the Germans off, Aurelian turned his attention to building a new wall circuit around Rome to protect the capital in the future.

Claudius Gothicus became Emperor in 268 and promptly lead the legions to victories against the Goths and the Alamanni. Unfortunately he died before he was able to reunify the Empire.

The near simultaneous deaths of Gallienus, Odenathus and Postumus upset the political equilibrium in the late 260s AD.

The 260s AD were bad for the Romans, but they could have been a whole lot worse had not Gallienus, Postumus and Odenathus each done their part to defend their respective corners of the Empire.  

Valerian and his son Gallienus did their best to hold the Empire together through the 250s AD, but after Valerian was captured by the Sassanids things quickly spiraled out of control.

After the Battle of Abrittus, Trebonianus Gallus was proclaimed Emperor. After reigning for two years he was ousted by Aemilianus, who lasted less than a month on the throne before being ousted by Valerian.

In 249 AD Decius ousted Philip the Arab and ascended to the Imperial throne. Two years later though, Decius was dead after leading the legions to a massive defeat at the hands of the Goths.  

Gordian III died in 244 AD and was succeeded by his Praetorian Prefect Philip the Arab. While Philip dealt with internal revolts and external invasion, he found time to celebrate Rome's 1000th birthday in 248 AD.

By August of 238, the other five men who had claimed a share of the purple were dead, leaving 13-year-old Gordian III as the last man standing.

In 238, a revolt in Africa sparked a revolution in Rome that would eventually lead to six different men claiming the title of Augustus.

After bungling a campaign in the east, Alexander headed to the Rhine where he was assassinated by Maximinius Thrax in 235 AD.

Alexander was only 13 when he ascended to the throne in 222. With the help of his mother and a few key advisers, he managed to avoid being the kind of disaster that previous teenage Emperors had been.  

Elagabalus became Emperor in 218 AD at the tender age of 14. His short reign was defined by a scandalous private life and an obsession with the eastern sun god El-Gabal. 

Carcalla was killed by his Praetorian Prefect Macrinus in 217 AD. Macrinus then spent a troubled year as Emperor before the House of Severus came back to challenge his rule.
