Monarchy over the Wizarding community
I'm writing a historical fic which takes place in 19th century England. I decided that the Wizards, like the Muggles, were ruled by a king/queen, but I'm having problems coming up with magical equivalents of the various admistrative functions of a ministry. So I have a few questions.
What kind of department would be controlling the life on streets? For example, if someone were pickpocket-ed in Diagon Alley, or something small-scale and ordinary like that, who would be called/summonned? A counterpart to, say, gendarmerie or police force?
I also appreciate any suggestion about how you think the wizarding community would be ruled in monarchic system.
Many thanks in advance :)
