Theodosius the Great divided the empire between his two sons in 395 AD
In the Roman Empire, the decline of the economy and trade did not affect all regions equally: In the western part of the empire, this phenomenon was more pronounced, while in the eastern territories, it had less impact
The West increasingly lagged behind the already developed East
Following this, Emperor Constantine, instead of Rome, had a new capital built for himself at the gateway of the East, on the shores of the Bosporus, on the site of the Greek-founded Byzantium, which he named Constantinople
The growing size of the military and the construction of the new capital required substantial funds, leading the emperor to raise taxes
To enforce tax collection, Constantine tied coloni (tenant farmers) and artisans to specific locations and occupations → To avoid taxes and harassment by imperial officials, small freeholders sought protection under the local large landowners, thereby becoming dependent as well → Together with the location-bound coloni, a new subjected class emerged, obligated to provide agricultural services
Emperor Theodosius reached a settlement with the Goths, recognizing them as allies = they could settle within the borders of the empire, living almost independently under their own king, effectively forming a state within the state
To enhance defense capabilities, in 395 AD, Theodosius sanctioned the de facto separation of the Eastern and Western provinces, dividing the empire between his two sons
The two new states, often competing against each other, attempted to weather the storms of the migrations
With the Gothic settlement, a wave of Germanic tribes began, primarily targeting the territories of the Western Empire
The eastern regions did not fall into the main direction of migration → due to a more developed economy and stronger state authority, the Eastern Roman Empire proved more resistant than the West
The gold of the Eastern Roman emperors and skillful diplomacy had their impact: the attackers turned their attention westward
The Goths were unleashed to the west
Steppes peoples mainly lived in the western territories, Vandals in Africa, Germans in Hispania and Italy
In 410, the Goths plundered Rome, the Vandals looted it in 455, the Britons and Saxons occupied the British Isles after the Roman withdrawal
