From 1460 to 1809
The history of the Iberian peninsula is almost unchanged up to 1468, when king Enrique VI of Castile and Leon's brother Alfonso died *here*.
Enrique died on schedule in 1474 and in a quick civil war Alfonso managed to get rid of Enrique's wife's daughter Juana and was proclaimed king.
Alfonso XII's sister, Isabella, had married Ferdinand II, king of Aragon, and there was no unification of Spain.
Both Alfonso of Castile and Ferdinand of Aragon continued their crusade against the Moors, and in 1492 the Caliphate of Cordova was decisively defeated, and both kings expelled the Jews from their kingdoms.
Alfonso, worried trying to compete with Portugal, who had circumnavigated Africa, and the Aragonese dominium of the Mediterranean, accepted the proposal of this Genovese sailor Cristopher Columbus, and sponsors an expedition to the Indies by navigating westwards.
Isabella and Ferdinand of Aragon have several daughters, including Juana, who marries Richard III, and Catherine, who marries the Habsburg prince Phillip. Their son, Charles, will become Emperor of the Holy Roman Empire as Charles V and king of Aragon as Carlos I, who was followed by Philip II (who also inherited the Netherlands), Philip III, Philip IV and Carlos II.
In Castile, Alfonso's son Sancho V is followed by his son Juan III, who also became king of Portugal as Joao IV, but this was barely a personal union. Juan's heirs - Alfonso XIII and Enrique VII - also ruled over Portugal (Alfonso VI & Henrique II) until Joao Braganza drived out the Castilian usurpers, and became Joao V of Portugal.
Enrique's son Sancho VI, was a contender to the Aragonese throne after the death of Carlos II. He managed to hold the Aragonese crown from 1700 to 1704, but he finally lost the Aragonese Sucession War to the Bourbons, and Philip V Bourbon become the new king of Aragon.
After Joao V, the Braganza dynasty in Portugal followed: Alfonso VII, Pedro II, Joao VI, Joseph Emanuel and Maria I.
In Aragon, Ferdinand VI, Charles III and Charles IV followed Philip V. Charles IV's son Ferdinand conspired with Napoleon and assumed the throne as Ferdinand VII after his father's abdication in 1808. Aragon and the Two Sicilies (under Ferdinand), became allied to France and their armies and navies part of the French Imperial Army and Navy.
In Castile, Sancho VI was suceded by his nephew Sancho VII, then by Juan IV and Juan V and Alfonso XIV.
In 1809, Napoleon attempted to take both Castile and Portugal. He managed to make Maria resign for his son Pedro and Pedro resign for Nap's brother Joseph, and both of them were made prisoners. Alfonso of Castile managed to escape to New Grenada denouncing Joseph Bonaparte as a ursurper.
