The main factors that led to the collapse of Western Roman Empire are due to
· The falling of the economy
· Poor Administration
· Extravagant Nature of the Empire
· Attack of Germanic Tribes
Explanation
Constantine, the Roman Emperor on 330 CE, divided the empire into two parts- The Western Empire whose center is in Rome and The Eastern Empire whose center is in Constantinople.
After the rule of Constantine, agricultural sector dropped thereby boosting the prices of food.
In addition, The Western Empire lived luxuriously by purchasing costlier items from the Eastern Empire in return for nothing.
Succeeding, Germanic tribes conducted invasions over Western Empire and in 470 CE, the last emperor of the west, Romulus was dethroned by the German tribes.
