My pleasure. I’m not sure whether I have a favorite historical period; 19th century America (that is, before flight, autos, telephones, electricity) has some appeal from time to time. :’)
For whatever the reason I have always been fascinated by medieval history, especially England and France during the Hundred Years War. I am also intrigued by the way certain events (in particular the Black Death) lead to the emergence of the middle class and the basis for mercantilism.
