Franconia/Bretonnia- france (new culture frankish/bretonnian)
Dutch League/Confederation- lowlands
Iberian Commonwealth- united iberian peninsula (new culture iberian)
The Trade Princes- northern italian (uniting venice, genoa, and milan)
Swiss Reich- alpine region (something to the effect of ultra nationalist/fascist switzerland (though this may overlap with The Trade Princes it could still be a cool idea))
Latin Empire- byzantine region (new culture latin, catholic byz, maybe another ultra nationalist nation)
Wendish Empire- southern baltic sea regions such as pomerania, to, lo, parts of lithuania and poland (new culture wendish, best to just look on the ck2 wiki for exact area)

Most of these sound great. But if I was to add the Swiss Reich one, I would call it the Switz Reich.

Ah yes of course, btw just to ask is this discussion also over non formable nations (as in nations formed in 1444) and also about national idea speculation for new nations?

All of these nations need to be formed, at least until I create new bookmarks, and National Ideas are always welcome.

The Trade Princes National Ideas (i've added suggestions for names, might do the full descriptions if your interested, also of course feel free to change and move these around as you see fit):
Traditions: -35% Mercenary maintenance, +15% Global trade power
La flotta davanti a tutti: -20% Ship costs
Grand admirals: +2 Naval leader fire
Establishment of merchant guilds: +1 Merchants, +10% Trade efficiency
Unify the nation: -2 National unrest
Espandere la frontiera: +20% Colonial range
Merchant marine: -25% Light ship cost
Productive Peasantry: +15% Production efficiency
Ambitions: -5% Technology cost

I have made the Trade Princes and I am in the process of making the ideas. I would love the descriptions if you could make them.

La Flotta davanti a tutti- "The foundation of any great nation lies of course with it's navy, as such our princes dockyards are hard at work to produce the strongest armada to defend our shores."
Grand admirals- "Our admirals have long been respected in the mediterranean as the most skillfully trained and versed in combat strategy."
Establishment of merchant guilds- "The mercantile class has long been the backbone of the princes economies, yet until now they have operated independently competing for every scrap of fur and every grain of salt, but no more! Now merchants trading in similar goods work as a coordinated force against all other nations."
Unify the nation- "Finally the council of princes have come together to decide upon the one true 'Grand Prince' to lead our nation to glory, no more will we have to deal with the faults of our lesser princes administration."
Espandere la frontiera- "While other europeans reap the benefits of the new world we sit here twiddling our thumbs, however now with the acquisition of superior shipbuilding methods our traders will spread far and wide in search of new goods."
Merchant Marine- "Often have we called upon our merchant in the defense of nations sovereignty, but now with a new 'Office of Merchant Services' we are never in need of volunteers to bravely lead towards our foes, to victory!"
Productive Peasantry- "The peasantry have been overlooked and undervalued for too long, now with the founding of overseas territories peasants finally have a chance to advance in society, this new fervor can be felt across the nation and we may reap the benefits."

Thank you for your conrtibution.

no problem, i really enjoy doing flavor and such, wish i could help you more modding wise however i've never taken the time to learn, ill probably drop another group of national ideas for one of the formable nations, if ud like me to prioritize one set over another (and looking back at it the dutch league doesn't sound very interesting, perhaps something like the 'Benelux Republic' would be a better name) just let me know.

The Switz Reich national ideas (most of this is a mockup of the regular swiss ideas but with a nice nationalistic flavor to it):
Traditions: +20% National manpower modifier, +15% Infantry combat ability
Cantons raise personal armies: -30% Regiment cost,
Swiss mercenaries: -40% Mercenary maintenance
Alpine defensiveness: -25% Fort maintenance
Switzerland for the swiss: -15% Culture conversion cost
Swiss intolerance: +2% Missionary strength
Wir nehmen keine gefangenen: +5% Discipline, +10% Morale of armies
The canton pact: -0.10 Monthly autonomy change
Ambitions: -25% Aggressive expansion impact

Cantons raise personal armies- "The 8 cantons united by the idea of a more serene alpine empire have raised their own armies in service to the führer!"
Swiss mercenaries- (copy from swiss ideas)
Alpine defensiveness- (copy from swiss ideas)
Switzerland for the swiss- "They took our jobs!" (south park reference) or "The french swine will stop at nothing to undermine our great nation, we must reclaim our rightful land and our people's liberty."
Swiss Intolerance- "The religion of the führer is the religion of the people, any who object shall be swiftly silenced or re-educated."
Wir nehmen keine gefangenen- "When our great regiments march across the battlefield routing lesser nations forces we often find ourselves with an overabundance of captives, we shall not waste our time with these people. They shall die on the battlefield today or in a cell tomorrow!"
The canton pact- "Though the cantons have always been loyal to the führer, he wishes for supreme power, yet his greatness has allowed the rulers of the cantons a new life as miners. Lang lebe der führer!"

Franconia national ideas (aka france can into more op):
Traditions: +30% National manpower modifier, +1 Diplomats
Revival of the frankish tongue: +1 Diplomatic relations
Elan!: +25% morale of armies
Expand the bureaucracy: +20% National tax modifier
Building of the maginot line (maginot line was built in the 1930's, so with the extension of the game to 1950 i'm assuming this is fine): -20% Fort maintenance, +30% Fort defense
Restoration of house karling (idk if unlocking a national idea can trigger an event but if its possible adding a karling heir to the throne would be amazing): +2 Yearly legitimacy, +1 Yearly prestige
Fund the universities: -20% Technology cost
Liberté, égalité, victoire: +2 Tolerance of heretics, +2 Tolerance of heathens
Ambitions: +10% Discipline

Revival of the frankish tongue- "For too long we have spoken a bastardized language. We must bring back the language of our forefathers and teach it to all who are willing."
Elan!- (copy from france)
Expand the bureaucracy- "With the hiring and training of more competent bureaucrats we are able to collect taxes more efficiently, even the bourgeoisie cannot escape our tax collectors."
Building of the maginot line- "In defense of our nation and the frankish people we must construct the mightiest fortifications in all of europe to hold steadfast against our enemies."
Restoration of house karling- "Glorious days!!! By some miracle or another a branch of the magnificent house karling has been found in southern france, though the kingdom has not had a karling on the throne I the king will adopt the most capable of the house. Long live the old house Karling!"
Fund the universities- "Our nation has always funded the science and the arts, but now we shall move our support to move conventional institutions."
Liberté, égalité, victoire- "We are all children of god and yet we are divided in our religious beliefs, yet equality and freedom of religion is a universal right to all our citizens, onward to victory!"

Been taking a little break. Will add Franconia, and the Switz Reich now.
