What did Constantine do to help reunite the empire? He forced all Roman citizens to pledge allegiance to him.
He moved the capital to a better location for defence and trade.
He cut the size of the empire to make it more manageable.
He made Christianity the sole religion, to unite everyone.

Found this off of google, "Constantine now became the Western Roman emperor. He soon used his power to address the status of Christians, issuing the Edict of Milan in 313. This proclamation legalized Christianity and allowed for freedom of worship throughout the empire. ... In 324, Constantine defeated Licinius and took control of a reunited empire."

So, the answer to your question is D)He made Christianity the sole religion, to unite everyone.

Hope this helps have a great day and stay safe! :) :D :3

the ss was the main organization responsible for the genocidal murder of around six million people of european ethnic minorities, essentially jews, in the holocaust. the members of all its branches committed war crimes and crimes against humanity during the second world war (1939-1945). likewise, the ss were involved in commercial enterprises and exploited the inmates of the concentration camps as slave laborers.

the tortures and assassinations committed by the ss were the result of an ideology developed long before the armed conflict, this ideology was based on the racial supremacy of the germans over the rest.
