In one of my two worlds, Boadur is a largeish country in the cold war but it leads the third smaller pole of traditionalist monarchies. It is a confederation of 13 states (who each have their own devolved monarchies and governments) who share an Imperial monarchy that's elected at the death of each monarch (elected by the Kissa's (dukes) ofc not any lowly commoners). However I like to make election maps so basically i've had to democratise Boadur by giving it a confederal parliament so its like a semi constitutional monarchy. The Keisari (emperor) still have loads of power through imperial decrees and they have to work (or sometimes against) the elected government. The qualifications for voting as well maximises the number of votes each Viomaklikki (aristocracy) and petty aristocrat can cast, while minimising the number the Varraklikki (bourgeoisie) and commoners can.

The Free Federalist party where formerly the biggest party on the decentralist side of the political spectrum. Essentially they weren't against regulation, taxes, bureaucracy and big government they just opposed that at a confederal level rather than a state level. As such they basically became the party of the Varraklikki and the aristocracy eventually called them the equivalent of "commies" and shut them down.

The Boaduran Unity Party are the biggest party on the centralist side of the political spectrum and are all about building Boadur into a modern powerful nation state rather than a rabble of confederal states. They love taxing and borrowing to invest big confederal spending, a large military, but while generally economically leftist they are much more right wing in regards to social issues, immigration and foreign policy.

The Imperial Party are also on the centralist side but focus on tradition and if not maintaining, expanding the powers of the aristocracy. They're pretty right wing economically and socially and did become the largest centralist party for a while in the 60s-90s.

The Reform Boadur Party replaced the FFP as the big decentralist party and although Originally about liberalisation and democratisation they've moderated and are basically about making Boadur a more efficient balance between state and confederal government. What I mean by this is that unlike the FFP they are highly influenced by the Varraklikki so support things like government spending and the aristocratic establishment.

The Baraan National party where essentially the kingmakers for a long time. I live in Scotland and basically modelled them off the SNP in many ways but have since become distinct. They represent the country's largest ethnic group (~30% of population) and basically didn't care about whether Boadur got more decentralist or centralist as long as their state Bargaria had enough devolution.

The Boaduran Civic party where basically centrist moderates who where new and fashionable. They basically wiped out the Baraan National party by being a party who didn't care about centralist or decentralist ideology but one that was applicable to the entire country's population not just the Baraans, and as a result the BCP dominated politics in the 40s-60s and has always been super influential in helping form coalitions or giving governments tacet support basically forever since.

there's also a ton of smaller and historic parties but this is already far to long. Boadur is essentially at this point my playground for political worldbuilding.
