What societal change during the classical era did the most to improve all aspects of life?

this is a good question! i'll do some research and come back when i have the answer!

depending on what kind of map for example a pltical maps works in many ways this iss how it works it shows the areas and places the democratics and the repbulcicans reside for example if   texas chooses trump for president there a republican state and if   califronia chooses hillary there a democratic state.

i think 3 documents.

hope i
