They brought back golds and silvers
I assume your talking about the HUNS... When the empire split in two the east had more gold and more resources and the dying west had to suffer all the barbarian attacks like the huns... The East quite simply was more prepared and had more walls and guards to defend their border also the Eastern Empire had the river danube north of them which helped deflect the Hunnic invasions and other barbarian invasion more west...
1. The agreement of Defense Alliance which is contained if one country being attacked then the <span>allies must helping.
2. Imperialism which is mean when a country try to colonize another country to take all the natural resources for themself
3.Militarism which is mean the war of weapon.
4. Nasionalism it caused by Slavia nation in Bosnia and Hergezovina don't want to be a part of Austria-Hungaria, but they want to be a part of Serbia, but mostly every countries in Europe were trying to prove their domination and their power
