In Italy the King-Emperor is more of a Constitutional monarch, with an Italian Parliament seemingly holding much more power than the one in London (in a story set in Italy, a local policeman emphasizes that his oath of office is to the Parliament rather than the King). There is no mention, however, of whether the parliament is appointed or elected, and by whom. Italy being united implies that the Catholic Church was, like in our history, deprived at some time of its Temporal power over the city of Rome and its environs, but there is no mention of when and how this happened.
