A Title Much Cooler Than Anything on the Old Site
Yeah, the right or duty to bear arms throughout history and like most things was more complicated than generally depicted. The Assize (edict) of Arms of 1181 A.D., issued by Henry II of England, is often cited as the earliest document recognizing the right to bear arms. Aristotle and Cicero wrote specifically about the right to bear arms as necessary to the free citizen, but I don't know if that was codified in the laws of the Greek city states or the Roman Republic. The Assize of Arms of 1181 was intended to support the rapid creation of a militia but permitted them to be carried in self defense. In the Ming Dynasty in China (14th to 17th century), there was a system where a certain number of men from every village had to go to military training and after they were discharged returned to their villages with weapons to help defend against bandits, etc. I suspect that throughout most of human history in most places, the trusted citizens (yeah, a lot of caveats there) were allowed or expected to have arms.My only real point was that there was no "Nobles would never arm the citizenry" precedence, and yeah I obviously oversimplified some ideas of why different countries took different approaches.
How historical precedence applies to a fantasy world is really largely in the hands of the author because why societies make the decisions they do even in the real world is open to debate.
The more relevant question is that how many would have the arms necessary to take on a dragon? I suspect that depends on how common of a threat dragons are. In a fairly high-magic world like D&D, I would expect that not only would vulnerable areas have protections, but as another poster stated above, governments would actively go after the threat, either with specially trained and equipped troops and/or through bounties. Or, given that dragons are intelligent creatures, treat with them to use them against their enemies.
