After the two twin boys, Romulus and Remus are abandoned by their mother in the forest, a wolf found them and took the twins and raised them both as his own.
Randomly, a shephard is walking through the forest when he sees two little baby boys with a wolf, goes over there and grabs the boys and takes them home. With the wolf putting up a fight the shepard was too strong and happily raised a happy family.
While the shephard teaching the boys a lot, the boys were already in the path of being a natural leader.
The two twins worked very hard to accomplish, founding a new city. They had to really think about where the city was going to be. They even considered consulting with the gods to determine which hill would be best to use.
Romulus started to build a wall around Plantanine Hill, but that made Remus jelous so while trying to show off, even with the wall built, Remus jumped over the wall to prove a point and that made Romulus very angry, which encouraged Romulus to kill his brother. In that moment Remus was dead.
After Remus died, Romulus continued his plans with his city. He offically founded his city on April 21, 753 BC
