There was only a single Roman Empire, even after 395 CE, but with their own governments. Fergus Millar rightly described this as the "twin regimes" of the Empire.

After all, Justinian restored Imperial authority over several western regions (including the city of Rome), which in some cases lasted several centuries. In Apulia even half a millennium!

The same could be said about other states, empires or polities, all the way from Punic Carthage to the Crusader fiefdoms in the Levant to Nazi Germany. The Roman Empire, on the other hand, makes for a much more daunting case.

2. Bret and I agree that already during the Roman Republic non-citizen soldiers played a crucial role in Rome's military. This is a staple throughout Roman history, from beginnings to end (= Byzantium). Scholarly consensus galore. Musk's original tweet was a racist dog whistle.

He covers all the era's and various domains (politics, economy etc). That said, even in the 2nd edition there are still a series of minor errors. But other surveys also have their virtues and vices.

Firstly, there's nothing wrong with giving people interested in Roman history suggestions on where to start! The suggested list, however, is at risk of being two-dimensional at best.

These days it's shorthand for the end of the Empire in its western provinces during the fifth century. After all, the Roman East continued for another millennium (wrongly and anachronistically called 'Byzantine')

2. Ancient/Modern comparisons almost never work, even though they're fun to play and think with. Especially the 'fall of Rome' (more on that soon) has proven highly popular to explain major problems of our time. I've written about this in Dutch here:
2. First things first: plenty of textbooks and studies still refer to him as the 'Vandal', 'Half-Vandal', or - horresco referens - 'German' Stilicho. These labels are incorrect/partially correct/rubbish. Often unmentioned, but most important label of all: he's a Roman. Why?
2. We don't know exactly what drove tribes of Greutungi and Tervingi to request crossing the Danube in 376. A combination of inter-tribal wars and the first tidings of the Huns in the steppe lands north of the Black Sea, may have motivated their leaders to request reallocation.

De realiteit is dat de tijd quasi voorbij is dat men een traject student-PhD-postdoc-prof aan dezelfde universiteit (of zelfs het zelfde land!) kon afleggen. Je moet jezelf en je werk live kunnen kenbaar maken aan de wereld. Dat betekent uiteraard niet automatisch jobsucces...

2. First: why can't we call this the end of the Roman Empire? Well, there was still a Roman emperor in Constantinople, who ruled the entire Eastern Mediterranean and Southeastern Balkans. Since the end of the third century, Imperial rule had ceased being centered on Italy.
2. The man who gave the orders was Alaric, who had had a chequered career as commander in the Imperial army. Looting Rome was the last thing he wanted: he had first arrived with his men near the Urbs in late 408. At any point in the next 18 months he could have taken the city.
