Which cultural impact was a direct outcome of the collapse of the western roman empire?

The senate became extremely corrupt and political instability came into existance. Consuls and officials would offer positions in office for those who could pay a lump sum of denarii (currency). Furthermore, they accepted bribes in exchange for favours of a wide assortment. A series of very incompetent, rather crazy Emperors were elected and the Plebians suffered as a result. Civil revolts sprung up, lead by rebellious citizens. 

2. Emperor Constantine divided the empire into two halves. He declared Constantinople the new capital of Roman society, claiming rule over all Eastern provinces. The Western Roman Empire lost its power over towns in the East, causing a great reduction in profits from the treasury and weakening them dramatically in warfare. Now their strength had been dwindled.
