Ck2 Merchant Republic Vassal
HF: Being Doge is a huge advantage because it gives you control over all assets in the Republic; levies and taxes. Of course, you also get to dictate top level foreign policy. This expansion fills in one of the remaining blanks in Crusader Kings II - the great merchant republics of the era.
Perhaps could you give a vassal a city and then marry into them to make your relative a grand mayor from there you would have to somehow make them the main inheriter, perhaps through making them a duke and electing them. Because their main title was a grand city they should be a doge, no?idk if this would work as ive just made it up and, ill be honest, fabricating claims and inheritance isnt my forte though i do like to dabble i mostly rely on holy war.Republics can be landlocked though it doesnt help them.
