Video transcript

in the last video we talked about the first two hundred years of Rome being an official Empire starting with Augustus in 27 BCE going all the way to Marcus Aurelius and that time period is referred to as Pax Romana Roman peace it's a relatively stable relatively a peaceful time for Rome now all of that is relative if you're one of the tribes that are still fighting with the Roman legions if you're one of the roughly one-fourth to one-third of the population that is a slave you might not view this as such a good time but things only get worse after the death of Marcus Aurelius who's viewed as the last of the five good emperors so to speak his son Commodus takes over and Commodus is the beginning of a succession of emperors for less and less competent who are the Empire becomes more and more corrupt less and less stable and things really come to a head and start to decelerate even further or I guess accelerate downward even further in 235 C II when the Emperor Severus Alexander is assassinated and this throws the empire into a 50-year crisis called the third century crisis because it happened in the third century and over this 50 years there's 26 claimants to Emperor the Empire is temporarily split into three different states there's a tax from the east from the sassanids the sasanian empire they're the successors to the Parthians you have attacks across the Rhine and the Danube from Germanic tribes all of that makes us a very unstable period for Rome now the third century crisis is considered to end in 284 with the Ascension of Diocletian and Diocletian is viewed as a somewhat or a reasonably strong Emperor he's known as the last emperor that really persecuted the Christians because they didn't follow the Roman religion they did not they did not worship the Emperor as a God but he's also or maybe he's most famous for splitting the Empire he decides that probably one of the main causes of the third century crisis is that the Empire has gotten too vast it has too many borders it's hard for one Emperor to administer the whole thing so he splits it into East and West from an administrative point of view he doesn't they don't become separate empires but he decides that he is going to rule from the east and that he will have a co Emperor who rules from the West and not only does he set that up but he had he sets up a what's called a Tetrarchy beyond himself and his Co Emperor they have a sect they each have a second-in-command that if any one of them were to die or would have to retire somehow that that second-in-command could take over and once again this is to address some of the issues of the third century crisis where the the wars for succession and this isn't just during the third century crisis we've seen in multiple videos Rome is famous even during the Pax Romana for these really ugly succession battles but as we'll see the splitting of the Empire into East and West even though it started as an administrative thing over time it's going to become a real split and they're going to turn into two different empires now after Diocletian you have another significant emperor you have Constantine and Constantine is known for many things maybe most famously he embraced Christianity as opposed to Diocletian who who persecuted Christians you have the the Council of Nicaea and then I see in code where there's now a uniform church doctrine around Christianity he has the Edict of Milan which makes Christianity legal under Roman rule maybe most famously on his deathbed he gets baptized he becomes the first Christian Emperor he also moves the capital to officially moves the capital of the entire Empire of the entire empire to what at the time was Byzantium but then he renames it to Constantinople named after him now he was still it was still one unified Empire Empire even Diocletian who cool ruled with a co Emperor he had veto power over the Emperor to the west now as we get further into the fourth century here and especially into the fifth century will see that the empire further and further fragments and gets diluted and really just breaks down one major factor in that breakdown is in that fourth century in the fourth and fifth centuries you have a group called the Huns coming in from Central Asia coming in from northern Europe right over here and they are fierce nomadic conquerors and they're so fierce that they start pushing more of the dramatic tribes across the Rhine and the Danube and a lot of these Germanic tribes at first even though their history has been fighting the Romans a lot of them try to seek refuge in the Roman Empire and they're given refuge in the Roman Empire but while they have that refuge they're treated very very very badly and all of that comes to a head in the like as you say the last quarter of the fourth century with the Gothic wars and the Gothic wars really have a decisive battle at adrianople originally Hadrian appleís named after the Emperor Hadrian and Adrian appleís at Adrianople the Gothic tribes in particular and when we say gothic we're really talking about Germanic tribes and this one in particular as you can see from this legend right over here this is the Visigoths sore western gods they're able to decisively defeat the eastern Roman Emperor Valens he's actually killed at Adria noble and then the Visigoths just continue to hang out here in in the Roman Empire and they continue to move forward in 410 they're able to actually sack Rome and they eventually settle in the Iberian Peninsula and in southern Gaul now after the Battle of Adrianople you have another significant Emperor Theodosius because what you'll see is is that Diocletian persecuted Christians Constantine now embraces Christianity he becomes a Christian he says Christianity is legal Theodosius now right as we are about to enter into the fifth century he makes Christianity the official religion of the Roman Empire so in roughly Han years the Roman Empire went from persecuting Christians to making it the official official religion and actually going the other way starting to persecute some of the pre-christian religions or rituals the other thing that happens as we enter into the fifth century now the as we go into the fifth century you have the the capital of the Western Empire is moved from Rome to Ravenna with the idea that you would the the Emperor's see all of these Germanic tribes they feel threatened by them that Ravenna is easier to defend it's surrounded by kind of marshy swampy area the other thing of note about Thea Dacia Theodosius and as we move into this this this really the last century of the Western Roman Empire is Theodosius was the last Roman Emperor to rule all of Rome after that the East and West are going to be ruled essentially independently they're essentially going to be separate empires but then as we get into the fifth century we already talked about the Visigoths sacking Rome then in 455 you have the Vandals which is another Germanic tribe that was similarly originally pushed out by the Huns you see them in blue right over here they make it down the Iberian Peninsula into North Africa they eventually get to Carthage and they become a little bit of a naval power and they eventually are able to in 455 sack Rome as well so Rome is is really taking a hit multiple times and then finally the the end of the Roman Empire or the Western Roman Empire what most historians consider the end of the Roman Empire is when the Germanic ruler general otto a cirrhotic are depending on how you pronounce it is able to ask the emperor in ravana and Ravenna and so then you have the official and it just to be clear this isn't this is rote let me write Roman Empire and so odoacer is able to essentially end the Western Empire as we know it and after that the Western Empire becomes more and more fragmented into these kingdoms that are ruled by essentially Germanic kings and that we are now entering into the Middle Ages now the big question that historians have a lot of fun thinking about is why did all of this happen why did the Roman Empire fall and before we even talk about why it fell it's we should give them a little bit of credit even in this video where I talk about the fall of the Roman Empire I'm covering 300 years of history and if you start with the founding of the Republic until odoacer takes over Ravana outs the Emperor we're talking a thousand years most civilizations most empires don't last anywhere near that long so to some degree there's it's it's surprising that it lasted so long but in terms of the causes of its decline we've talked about several of them in this video the Empire got divided the east and west stopped viewing themselves so much as the same Empire trade sometimes broke down they didn't support each other militarily the Eastern Empire was generally stronger so it allowed invading tribes to focus on the weak point in the West some historians would say that the Roman Empire stopped expanding and it needed that expansion in order to keep getting more land and more slaves that really drove its economy one major factor probably was the Huns that caused this great migration in the 4th and 5th centuries that caused the Germanic tribes to cross the Rhine and cross the Danube and become either pot or either settle as part of the Roman Empire or threaten the Roman Empire another theory and all of these are probably contributors is that as a Germanic tribe settled they actually became more and more part of the Roman military and some of them were were officially part of the military some of them were mercenary soldiers for fortune paid soldiers and so you can imagine their allegiance to Rome was not as strong some folks say Christianity may been a factor that the Empire might have lasted especially when people were doing what their traditional rites rituals they worshiped an emperor but not Christianity wasn't about worshiping an emperor anymore a lot of people think it's corruption instability and we've talked a little bit about that it could have been invasions not just from the Germanic tribes and the Huns but also the sassanids on the east so I'll leave you there and to think about what was the cause or maybe what allowed the Roman Empire to survive for so long
