It depends on your reforms. Monarchies without voting will be absolute, monarchies with voting but only Gerrymandering or worse in Political Parties are Prussian Constutionalism. Monarchies with voting and Non-Secret Ballots or better will be HM's Government.
For Dictatorships, passing voting laws will make you a democracy. To go from Democracy to Dicttaorship you either must have rebels enforce their demands or when Reactionaries/Anarcho-Libs/Communists/fascist are in power they will turn your country into a dictatorship by event. To become a Moanrchy as a Democracy, Reactionary Rebels must break you twice in a row. To become a Democracy as a Monarchy, Jacobin Rebels are the way to go.
