can anyone tell me why Wisconsin is called the Badger State?

Question

just the history behind that of why?

Answer 1

Back in Wisconsin's history, all the way back to the 1800s, miners dug tunnels into hillsides as they searched for lead and then lived in them during the winter months to keep warm. This reminded people of badgers and Wisconsin became known as the badger state.

Answer 2

Because the one whe named it had a mother-in-law from Wisconsin
