First: Form of government - it was hotly debated who should held major power.
Parliament (parliamentarism) or the head of state (presidentialism/his majesty's government)
Head of State.
Second: Head of State - it was debated who should be the new head of state an
elected president (Democracy) or an appointed monarch (Constitutional Monarchy).
Elected president.
Third: Civil Rights - probably the most discussed subject. Universal Suffrage vs voting
rights only for the educated was the main subject here. Whereas freedom of the press,
speech were thought granted for free as well as freedom of assembly and association.
Universal suffrage.
Fourth: Form of Parliament - The delegates from urban areas argued for a one chamber
parliament like the house of representatives. The delegates from rural areas on the other
hand argued in favor of a two chamber parliament including a second chamber like the american senate.
One chamber.
Fifth: How the Kingdom of Platinea would be called in the future. The major debate was
about renaming it into Argentina or not.
Unión Federal de Platinea (Federal Union of Platinea).
Seventh: Parties - As the three old parties (Unitarios, Partido Real, Partido Federal) broke
down during the revolution it would be necessary and inevitable that other parties would
take their place. Besides the fact that their would be no longer a royal party the future of
the platinean party system was unclear.
1) Reactionaries. Old Carlists. Aristocrats. Hated by liberals, marginalized by conservatives. Not in power and never should be. Interventionism, protectionism, residence, moralism, jingoism (Carlist cause).
Partido Agrario de Platinea > PAP (Platinean Agrarian Party > PAP).
2) Conservatives. Supporters of the Prince. Rural folks, moderate landowners, common soldiers [who didn't join the revolution] -- those who distrust the revolution should join forces here. Big party, strong, and probably will share power with the liberals in a National Coalition for the first few years after the revolution. It's a big coalition so choose their policies depending on the way your story is shaping up.
Bloque Conservador > BloCon (Conservative Block > ConBlo).
3) Liberals. Capitalists, clerks, moderate former revolutionaries who are willing to compromise with the conservatives and the prince. Big, strong, and I think should form a coalition with the conservatives story-wise for a few years at least. I don't know of Argentina's specific condition so I don't know how their liberals at the time would think.
Federación y Democracia > FYD (Federation and Democracy > FAD).
4) Anarcho-Liberals. Revolutionaries who refuse to compromise with the prince. Consequently, marginalized. Consider themselves "betrayed." Laissez-faire, free trade, full citizenship, secularized, anti-military.
Estrella Sureña > ES (Southern Star > SS).
