In colonial America, Africans "contributed" to society by being a source of income for people who bought and sold them into slavery. They also contributed by being laborers in the southern plantations.
Women contributed to the society by being a house wives --meaning they took care of the house-- as well as cooking meals for the family and taking care of the children.
Native Americans, in the earlier days, contributed by trading with settlers and teaching them how to do things in their environment.
(Sorry I really don't know what the children did)
The answer is yes, definitely. The Roman empire grew so big that their sphere of influence reached even China (through trade most probably). There are so many achievements that the Roman empire can boast, one of which is none other than achitecture. You may not notice it, but if you look closely you'll see that most of the government's structures and or bank's structures have Greco-Roman touch about them.
And definitely you will notice that there are many Christians here and there - that's brought to you by the Roman empire who grew so big that when emperor Constatine decided to legalize Christianity, the religion spread like wild fire in the old world! This development still affects us up to now. Where is the pope's seat of power? Is it not in the Vatican, the heart of Rome?
