Often in historical media you may see an offended party challenge another to a duel over various matters. Was this truly as prevalent as Hollywood makes it? If so were there universal rules regarding duelling? When did it die out and why?
Unfortunately it is Football time, so I don't have time to write much, but I've written several previous answers about duelling so would encourage you to check these out, especially this one. Happy to respond to any follow ups you have later.
