Rome wasn't named in a day

So it wasn't one city. It was two cities. The story of the two brothers is ultimately a story of the importance of the state. A common theme of Roman works and neo-classical works, is that the state is the most important thing, more important than your family. The story of Remus and Romulus is that both had these up and coming cities but when it came to security and trade disputes, the cities and its members were always fighting. To resolve this, Remus wanted to cooperate, but Romulus wanted to destroy Remus and his city, basically setting up how Rome would continue to educate its members. That when it comes to the state or your family, pick the state. Also I just know the story and some art history so actual historians please correct me.
