I believe this is a true or false question... So im going to say True.
Puerto Rico is a living example of this statement.
Rome treated the people of the conquered land with same privileges
as their own people. The senators of the conquered land were given all the
facilities received by the Roman senators. The people slowly absorbed the Roman
culture and so the chance of further rebellion reduced greatly. The general
people were given the opportunity to watch and play lavish games and were also
given equal share of food as the other general Roman people. The Italians were
won over by the Romans in the same way.
The practice of enslaving people is contrary to Christian principles
