You have forgot the Catalans!
Let me do some explain of who we are and who we've been:
Our history begins at IX century with the creation of the Spanish Marche by the frankish king Charlemagne, once the muslim invasion was stopped. After Charlemagne, the Marche dispersed into counties and reigns, then the catalan counties -located in the eastern extreme of the iberian peninsula and in the both sides of the Pyrenees Mountains, under the leadership of Barcelona's one, begin to adquire personality.
By marriage ans alliances, the catalan obtained some counties at Occitania (southern France), including also Provence (and his capital, Marseilles) ans Montpellier. A war between catalan and frankish factions resulted as the loss of catalan influence at Occitania. Also, the Kingdom developed a Parliament (Corts Catalanes), one of the firsts, if not the one.
At XII century, the Count of Barcelona managed to marry the crownprincess of the Kingdom of Aragon, adquiring the title of King for Barcelona's dinasty. Then, the Reconquista advances quick, and the catalans conquered the Balearic Islands and the Valencia reign to the moors, but stopped by the castilians at Murcia.
Then begins 'The Happy Overseas Expansion': The Cont-Kings of Barcelona begun the conquest of very important places in the Mediterranian Sea. At the top of the conquests, got captured Corsica, Sardinia, Sicily, Malta, Naples Kingdom (including rights to rule Albania) and Athens-Neopatria. This era finished at the XV century.
The catalan dominions at 1443:
By and from the dinastic union with Castile at the end of XV century, the two reigns share the same king, but not merged in any political or institutional union. In fact, castilian kings must be recognised by the catalan to rule (the kings were named Kings of Castille, Aragon and Counts of Barcelona -legally Spain does not exist and isn't recognized-)
At the finish of the Sucession War this ended: the right-to-choose (sovereignity) of the Parliament was used to recognice as King a Habsburg family one, while Castilla accepted the Bourbon. After the Habsburg (king Charles) has the Crown os Austria, the international coalition left the catalans alone in the war. Bourbons and Castilla won, the Kingdom was dismantiled and castilian-like laws and institution were imposed. This is the way Spain -legally- was created and internationally recognized.
Some claims for the "devolution" of the historical institutions and laws were made from this moment on, specially with the two spanish republics and the Carlists Wars -internal ans real wars between tho branches of royal family-)
In modern days, we were divided into a french department, the Principality of Andorra -a free state-, and three spanish administrative divisions. The last ones got political autonomy, specially Catalonia. Catalans were proud of their history, got a nationalist majority on his Parliament, an independentist party at the government and only a tiny minority feels more spanish than catalan, in spite of massive spanish migration to the area.
Proposed leaders...
maybe Jaume I "el Conqueridor" (the Conqueror)
and Francesc Macià "l'Avi" (the Grandfather)
