ELI5: Why is there a Springfield in every state?
gpt
Basically because people used to name cities after other cities, like how a lot of cities in the New England area are named after cities in England.  The first Springfield in the US was Springfield, Massachusetts, itself named after Springfield, Essex.  During the Industrial revolution, Springfield, MA became somewhat of a big deal, and other cities took its name.
