Cities built throughout the roman empire modeled their urban planning on what city?

Athens (Greece)

Explanation:

Rome builds many cities, somewhat similar to one another. The ideas of the cities constructions taken from Greece. Athens played a significant role in showing Rome urban planning. Roman adopted the method of building structures in enormous size as the Athenians, along with temples, markets, and meeting places.  Athens being a center of culture and art, helped Rome in becoming a center of architecture, trade, culture, and art.

Romans preferred a much more regular, rational layout and plan. They inherited the Greek tradition of city planning on rectangular grids but they refined it to include more open space and central public focus: the forum, a kind of city center where the most important civic buildings, temples and monuments would be located.

Soviet Union- Republican Party
One ruled party Gov by the communist party
United States- both democratic republican part

Basically, the Soviet Union has a bad gov. And a bad way of ruling their people!
The United States however has a wayyy better government system (besides the fact that it’s overruled). And politically, we are better than them. We are free as a people and what that chart is saying, is it’s comparing government based places. In this case it’s comparing what a government is like ruled by both democrats and republicans(U.S) and a government ruled by one party, just republicans(Soviet Union).
