Answer:
I think that the Roman Empire and Han dynasty both contributed many innovations which changed the course of history before collapsing but I think that the Han dynasty contributed more. For one thing they made paper. And we all use paper. Without paper what would we print anything on. Another reason why the Han dynasty was better was because they the hot air balloon. The hot air balloon, we use now days and they are a nice way to travel/get around. A reason why the roman empire was less influential was because of their cruel punishments such as perfecting crucifixion and persecuting many Christians. All in all, Both the Roman Empire and the Han Dynasty contributed many innovations which changed the course of history before collapsing, but I think that the Han dynasty was more of an influence.
