why was the roman empire divided into two halves?
the empire was split up based on cultural and religious beliefs.
it was difficult to protect one large empire against invasions.
each half could more easily conquer other countries if they were apart. government officials disagreed over how to rule and thus split up.

The Roman Empire grew to be huge.  It covered most of Europe, North Africa, and parts of Asia.  Just getting messages from Rome to the outer parts of the Empire took weeks.  The Empire had become too large to rule effectively.  The outer provinces were pretty much doing whatever they wanted.

Emperor Diocletian was looking for a way to fix this and other problems.  He decided that the only thing to do was to actually break the empire into two pieces.

explanation:

japan participated in world war i from 1914 to 1918 in an alliance with entente powers and played an important role in securing the sea lanes in the west pacific and indian oceans against the imperial german navy as the member of the allies.

c) legal battles last five weeks after the election due to the narrow victory in several states.
