Can someone please help me with this question?

What was the significance of the vibrant city culture? The City Culture is around the 1870-1900's.
This is what I have so far: Everything in the world began to change. Technology and industry started to erupt over the world and the old ways were out. This was the causes of many of the conflicts in the 19th Century.
Thanks for the help.

You need to be more specific. What about plays, concerts, lectures? What about public transportation? What about the influx of immigrants from foreign countries? Didn't their varied cultures add to the vibrant city culture?
