mountains: ancient greece
- independent city-states developed due to no unity in the country
- people grew up in different cultures and with different lifestyles, an example of this would be athens and sparta (athens was democratic and sparta was a military state)
- limited interaction amongst the greek because it was difficult to navigate around the mountains
mediterranean sea: ancient italy
- location on a penninsula made trade more efficient
- sea location made imperialism easier as well
- unity in the country due to having mostly flat land
- people developed under the same lifestyle and culture because of that
you can really do anything for this thematic topic, i decided to choose ancient greece and ancient italy because it seemed like the easiest topics i could choose.
i hope this helps!
