Spain: The Politics of the Catholic Monarchs
Ferdinand/ Fernando II (King of Aragón from 1479-1516) and Isabella/Isabel I (Queen of Castile from 1474-1504)

On the morning of October 19, 1469, the marriage took place in Valladolid (Castile) between Isabella and Ferdinand, heirs respectively to the thrones of Castile and Aragón that would have far-reaching consequences. The omens were not favourable:

• they were both teenagers, the older, Isabella, being 18 years-old and her husband, Ferdinand, 17;
• Isabella’s claim to the throne of Castile was disputed, and Ferdinand’s claim to the throne of Aragón was endangered by civil war;
• since they were cousins they married in secret and required special papal dispensation, which turned out to be a forgery concocted by Ferdinand and his supporters;
• both had numerous enemies, and in Castile political conditions were chaotic, with powerful nobles determined to retain their influence.
Nevertheless, Isabella succeeded to the throne of Castile in 1474 and Ferdinand to that of Aragón in 1479. Together, Ferdinand and Isabella laid the foundations of Spain’s Golden Age (Siglo de Oro), a period during which it became the largest empire the world had ever seen.
However, some clarification is in order here:
• although both monarchs worked closely together in running the country, the interests of the Crown of Aragón were subordinated to those of Castile. In fact, of the 37 years that Ferdinand ruled, he spent less that 4 in Catalonia, even less in Aragón and 6 months in Valencia.
• both Castile and the Crown of Aragón (i. e. Aragón, Catalonia and Valencia) retained their own laws and customs;
• the Crown of Aragón included the modern autonomous communities of Catalonia and Valencia, as well as southern Italy (the kingdom of Naples) and Sicily and Sardinia;
• Castile because of its larger size and greater population dominated the relationship;
• the term “Golden Age” tends to view Spain’s achievements during this period through Castilian eyes (Catalans nowadays, for example, have a different view of the period).
Ferdinand and Isabella shared similar goals when they took power.
Nationally these goals included:
• peace and order through the reduction of aristocratic power and concentration of political authority in their hands;
• the support of the Cortes (Parliament), the body that represented not only the nobility but also the church and the municipalities;
• the conquest of the kingdom of Granada (the last Muslim enclave in the peninsula), and religious uniformity.
That these national goals were achieved says much for the organisational skills, astuteness and maturity of Ferdinand and Isabella**.
**Ferdinand’s political acumen, deviousness and strength of character were generously praised in Machiavelli’s Prince (1513). Isabella’s commanding personality is frequently portrayed as responsible for the creation of the modern all powerful role of the Queen in chess.
For the general public, the best known of these goals is the conquest of Granada in 1492, followed by the expulsion of those Jews and Muslims who refused to convert to Christianity. An added bonus to the fame of the Reyes Católicos (Catholic Monarchs, a title conferred on Ferdinand and Isabella by the Pope Alexander VI in 1494) was the achievement of Christopher Columbus, a Genoese sailor who set out from the south of Spain for India and found America, or Las Indias as they called it.
Perhaps less generally known is that it was during the reign of the Catholic Monarchs that the Spanish Inquisition became a feared social scourge. Long dormant in Aragón, it was introduced into Castile in 1478 at the request of Ferdinand and Isabella to investigate the religious orthodoxy of Conversos (Jewish converts to Christianity). However, since it fell under the direct control of the Crown, it became a political as well as religious tool, and was to have a profound effect on Spanish society for centuries.
On the international front, the Catholic Monarchs sought to contain the influence of Spain’s main rival, France. France had already annexed the Catalan counties of Cerdanya and Rossello (in 1463) and also invaded Naples (1495) which belonged to the crown of Aragón. Marriage was the most expedient way of setting up alliances to contain France. The Monarchs succeeded in this by marrying:
• their son and heir, Juan, to the daughter of the powerful Hapsburg Emperor, Maximilian;
• their eldest daughter, Isabel to Manuel of Portugal;
• another daughter, Catalina/Catherine to Prince Arthur of England. (Catalina is the famous Catherine of Aragón who married Henry VIII of England after the death of Arthur.)
An unfortunate sequence of deaths, however, had unforeseen consequences. Juan died without issue in 1497, and then the deaths of both Isabel of Portugal and her infant son soon after meant that the right of succession to the Spanish throne passed to another daughter of Ferdinand and Isabella: Juana, who –as it happens– had married Maximilian’s son, the Archduke Philip/ Felipe and was living in Flanders. Juana eventually succeeded to the throne of Castile upon the death of Isabella in 1504, but her father, Ferdinand, remained king of Aragón.
Fortune didn’t favour either Juana or Philip. Philip died suddenly in September 1506 when he’d hardly stepped on Spanish soil, and Juana –whose mental health was delicate–was soon confined to the isolated castle of Tordesillas. Since their son and heir, Carlos/Charles, was only 6 and living in Flanders, Ferdinand remained as regent of Castile (and King of Aragón) for 10 years, until his death in 1516. Charles’s arrival in Spain in the following year as King of both Castile and Aragón marks the beginning of the Hapsburg dynasty in Spain.
