We know that as the Roman Empire expanded it brought new ideas, inventions and cultural changes to its new territories, i'd like to know if the reverse happened, did this expansion expose the Romans to new ideas/ concepts and did any have a substantial effect on Roman society?

Hi there!

The answer is of course, yes. Just to cite perhaps the most blindingly obvious case of this sort of thing, Christianity surely qualifies as having had a "substantial effect" on Roman society. Here is a thread on the FAQ in which /u/Zosim deals with the rise of Christianity within Roman society.

Cheers!
