1B - The political, economic, social and religious condition of the Iberian Peninsula in 1469
Learn why the marriage of Isabella and Ferdinand began a difficult political project rather than creating a united Spain overnight. Compare the peninsula's states, resources, social divisions and religions to establish what their later policies could change.
A peninsula of separate states
The Iberian Peninsula in 1469 contained several states whose rulers, institutions and interests differed. Castile occupied much of the centre and west; Portugal was an independent Atlantic kingdom. The Crown of Aragon united the kingdom of Aragon, Catalonia, Valencia and other possessions under one monarch while preserving their distinct laws and institutions. Navarre lay across the western Pyrenees. The Muslim-ruled kingdom of Granada survived in the south-east.
Castile was larger and more populous than the peninsular territories of the Crown of Aragon. Its population and taxable resources offered considerable potential, but potential resources were not the same as money a king could readily collect. Great nobles held estates, towns and jurisdictions; some royal revenues had been granted away. The Crown of Aragon had an established Mediterranean outlook, including Sicily and Sardinia, but a shared ruler did not make all its possessions one administrative unit.
| State or crown | Political position in 1469 | Important distinction |
|---|---|---|
| Castile | Ruled by Henry IV | Isabella's succession remained contested. |
| Crown of Aragon | Ruled by John II | The kingdom of Aragon was one territory within a larger composite crown. |
| Portugal | Independent kingdom | Its Atlantic ambitions could compete with Castile's. |
| Navarre | Separate Pyrenean kingdom | Its position exposed it to pressures from neighbouring rulers. |
| Granada | Muslim-ruled kingdom | Muslim communities also lived under Christian rulers elsewhere. |
Composite monarchy
A monarchy in which one ruler governs several territories that retain distinct laws, privileges and institutions.
Isabella and Ferdinand married at Valladolid in October 1469. Neither then held the crown they would later inherit: Isabella's half-brother Henry IV ruled Castile, and Ferdinand's father John II ruled the Crown of Aragon. The marriage created a dynastic alliance and the possibility of future cooperation. It did not abolish borders, merge treasuries or settle the Castilian succession.
Contested royal authority
Royal government already existed in 1469, but enforcing it depended on cooperation that rulers could not assume. Castile had a royal council, courts and the Cortes, an assembly through which privileged groups and towns could petition the ruler and grant extraordinary taxation. Local nobles and urban elites could cooperate with the crown or obstruct it. A weak monarch did not mean a society without government; it meant several authorities competed over who could command people and resources.
Henry IV's reign was troubled by noble faction and disputed succession. Opponents questioned the legitimacy of his daughter Juana, a claim used politically rather than an established fact about her parentage. Henry recognised Isabella as heir in the agreement of Guisando in 1468, but her choice of husband made the settlement vulnerable. Rival elites could attach themselves to rival claimants, making dynastic disagreement a struggle over offices and privileges.
The Crown of Aragon presented a different problem. Its ruler was expected to respect territorial privileges, often called fueros, and negotiate with separate representative institutions. In Catalonia, civil war between John II and his opponents had begun in 1462 and was still continuing in 1469. Conflict over royal authority intersected with struggles between urban groups and between landlords and dependent peasants. The Archive of the Crown of Aragon's account shows that opponents even offered the crown to alternative rulers while keeping established administrative machinery.
These conflicts also brought foreign intervention. Portugal had an interest in the Castilian succession; France intervened in the affairs of the Crown of Aragon. Restoring royal authority would therefore require diplomacy as well as action against domestic opponents.
Resources and regional economies
Most people depended on agriculture, although the peninsula also contained important commercial regions. Castilian cereal farming, vineyards and livestock supported towns and taxation. Fine wool could travel through merchants at Burgos and northern ports to European textile producers. Andalusian ports connected Castile with Mediterranean and Atlantic commerce. The Mesta, an association of migrating sheep owners, helped protect the movement of flocks between seasonal pastures.
Such trade did not imply general prosperity. Drought, harvest failure and warfare could threaten subsistence. Difficult terrain, transport costs, tolls and regional boundaries obstructed exchange. A wool exporter might benefit from access to foreign buyers while a farmer suffered when pasture rights restricted cultivation. The same economic arrangement could therefore create wealth for one group and costs for another.
The Crown of Aragon was also economically varied. Barcelona had a long commercial tradition, but Catalonia had experienced demographic, financial and political difficulties, made worse by civil war. Valencia remained an important centre of Mediterranean commerce and agriculture. It would be misleading to make Barcelona's troubles stand for every Aragonese territory. Granada had irrigated agriculture, silk production and links with North Africa; Portugal was developing Atlantic trade and exploration.
Judge an economy through regions and groups: active export trade can coexist with rural poverty, and one declining city does not prove that every region is declining.
Hierarchy and social tensions
Society was organised around unequal status and privilege. Nobles and the Church possessed substantial land and exemptions; peasants owed rents, dues or labour obligations that varied by locality. Not all peasants were serfs, and not all nobles were equally rich. Great aristocratic families could control extensive jurisdictions, while lesser nobles relied on more modest resources and office-holding.
Urban society also contained divisions. Merchants, craftsmen, labourers and established governing families did not have identical interests. A city's political independence often meant government by a narrow elite rather than equal participation by all inhabitants. Competition over municipal office, taxation and commercial regulation could intensify wider struggles over the crown.
In Catalonia, remensa peasants were tied to their holdings and faced burdens known as the bad customs. Their resistance became entangled with the civil war. Some peasants looked to the king against landlords, while some opponents of royal power defended their own privileges. This explains why “monarch versus people” is too simple: a ruler might gain support from one group by restraining another.
The Church was both a spiritual authority and a major social institution. Its bishops, monasteries and orders owned property, provided education and charity, and participated in government. A ruler wishing to strengthen authority would need its support, but influence over church appointments and resources could also become contentious. Social hierarchy therefore supplied partners for royal government as well as sources of opposition.
Religious plurality and hostility
Christianity, Judaism and Islam all had established communities in Iberia, but their coexistence was unequal and often insecure. Catholic Christianity dominated the Christian kingdoms. Muslims living under Christian rulers were commonly called Mudéjars; Granada remained ruled by a Muslim dynasty. Jewish communities had their own religious institutions and included people in varied occupations, not a single wealthy commercial class.
Anti-Jewish violence, particularly the attacks of 1391, had led many Jews to accept baptism. These converts and their descendants were called conversos. Baptism formally made them Christians, but it did not always end hostility. Suspicion that some converts secretly practised Judaism could be directed against sincere Christians as well. Religious prejudice could combine with jealousy of successful office-holders or commercial rivals.
Converso and Mudéjar
A converso was a Jewish convert to Christianity, or a descendant of converts. A Mudéjar was a Muslim living under Christian rule while retaining Islam. These are different religious and legal positions.
The presence of minority communities mattered economically and politically, but religious conflict cannot be explained by economics alone. Many Christians regarded correct belief as essential to collective salvation. Rulers could present religious unity as a source of legitimacy, while minority communities faced demands that threatened their faith and security. In 1469 the later royal Spanish Inquisition had not yet been established; do not project policies introduced after 1478 back into this starting point.
