The term applies to a wider area
https://en.wikipedia.org/wiki/Lunigiana , although I suppose it might be used for a more specific area, as this map of Italy from 1499
https://upload.wikimedia.org/wikipedia/commons/4/4a/Italy_in_1499.png and, yes, Lucca is not shown as owning that particular version of "Lunigiana". In my defense it was shown
in these , and, as I said, I only have so much time to research these maps, especially when verifying fine historical detail on the internet is like stumbling blindfolded through the Turd Museum with your arms out, in hopes of putting your hands on a diamond . Let's just call it another ministate. I will admit I should have given Massa to Habsburg Parma to give it some coastline.
(I'm fine with suggestions on how to improve my maps, but I find your responses a little hectoring, a little "why did you miss this obvious thing." Perhaps I'm oversensitive - I have been on some new medication lately, and it affects my mood.)
