The Cast as of 1473
The Capetien Clan : the Houses of Valois
Louis XI "le Prudent", King of France (the Land of Wine)
He is known as "l'universelle aragne" or Louis the Spider King. He has spent the few first years of his reign trying to grab Burgondian lands and trying not to have his grabbed. This has stopped after the treaty of Péronne which instaured an uneasy peace between the cousins. (POD : Péronne is not invalidated) Since then he grabs others of his vassals' lands. He is certainly the most machiavelian king around, and is also a very competent administrator.
Economically speaking, France is still recovering from the not-yet-finished Hundred Years' War, but this is militarily speaking covered up by the well-trained, well-organized troops he inherited from his father Charles le Bien Servi.
Charles "le Téméraire", Duke of Burgondy and countless lands of Beer.
His nickname is well-deserved, being excessively brave and a bit rash. In his person he shows both the best and the worst of the Valois-Burgondy, as he is too pushy for fine diplomacy, but a very chivalrous duke, and his sponsoring of artists stained by his utter ruthlessness, as when he burnt and pillaged the rebellious city of Dinant. Ever heard of it ? It's because he burnt it.
He owns a massive prosperous realm whose main inconvenient is its being split in halves, the Burgondies and Netherlands. Had he a reason, or simply an occasion to invade Lorraine or Champagne, he would doubtlessly seize it.
"Le Bon Roi" René d'Anjou, Duke of Anjou, Count of Provence and Forcalquier, formerly titular king of Aragon and Naples.
An old man liked by his subjects in Angers and (especially) Aix-en-Provence. One of his daughters has married the Spider King.
Nicolas the First of Anjou, Duke of Lorraine
The grandson of René d'Anjou, whose claims on Aragon and Naples he inherited through his father Jean II of Calabria. He has been promised Marie of Burgondy. His death on July 27th, 1473, while trying to take Metz to round up his realm, will kick the butterfly flower.
The Trastamara Tribe (yes, I do it for the Added Alliterative Appeal)
Juan II de Trastamara, King of Aragon, Valencia, Majorque, Sicily, Navarra (usurping) and Count of Barcelona.
Juan is another old man. Old he was when he inherited the throne, and old he remained. Nothing noteworthy happened in Aragon after a civil war when he was 60.
Ferdinand of Aragon
The heir of Juan of Aragon. He just thought of marrying one of the women who are bound to fight for Castilla y Leon and married Isabella.
Alfonso V, (House of Aviz) King of Portugal and the Algarves.
The old man is having the same idea as Ferdinand of Aragon after a little crusading in Morocco and conquering archipielagoes.
Enrique IV, King of Castille and Leon
A weak-willed king who, after a little crusading in Andalucia, now sees his kingdom polarise over his inheritance between the allies of his daughter Juana (most Castillian nobles, France) and his step-sister Isabella (Aragon).
Ferrante of Peninsular Sicily (Naples)
One of the worst kings of Naples. Brutal and ruthless, he only reigns through coercition and terror. He is seen by his neighbours as a cruel and dissimuling King.
He had defeated Jean of Calabria, being the bastard son of the previous king of Naples and not his grandson through a woman.
The Habsburg Archduke
Friedrich III von Habsburg, Holy Roman Emperor.
He is very, very busy losing a war against Mathias Corvin. He is considering getting help everywhere he can. A bit weak-willed, he deeply admires Charles de Bourgogne.
His son Maximilian however shows great promise.
