There's a lot of high quality discussion here on determining historically realistic values for military/population/economic/etc parameters for cities-countries-etc.
I'm wondering if anyone is aware of or collecting historical datasets on these kinds of state parameters for the medieval/early modern periods. For example are there datasets on the relative military strengths / army sizes for the period of 1400-1800?
I think a database like that might be really worthwhile to make, as it would allow one to systematically look at the determinants and the limits of military size at the time. Books on particular places and eras is fine, but it is difficult to generalize from there. Thanks!
