The Crown of Aragon (//; Aragonese: Corona d'Aragón, Catalan: Corona d'Aragó, Latin: Corona Aragonum, Spanish: Corona de Aragón)[nb 1] was a composite monarchy, also nowadays referred to as a confederation of individual polities or kingdoms ruled by one king with a personal and dynastic union of the Kingdom of Aragon and the county of Barcelona. At the height of its power in the 14th and 15th centuries, the Crown of Aragon was a thalassocracy (a state with primarily maritime realms) controlling a large portion of the present-day eastern Spain and southwestern France, as well as some of the major islands and mainland possessions stretching across the Mediterranean as far as Greece. The component realms of the Crown were not united politically except at the level of the king, who ruled over each autonomous polity according to its own laws, raising funds under each tax structure, dealing separately with each cortes. Put in contemporary terms, it has sometimes been considered that the different lands of the Crown of Aragon functioned more as a confederacy of cultures rather than as a single country. In this sense, the larger Crown of Aragon must not be confused with one of its constituent parts, the Kingdom of Aragon, from which it takes its name.
In 1469, a new dynastic familial union of the Crown of Aragon with the Crown of Castile by the Catholic Monarchs, joining what contemporaries referred to as "the Spains" led to what would become the Kingdom of Spain under King Philip II. The Crown existed until it was abolished by the Nueva Planta decrees issued by King Philip V in 1716 as a consequence of the defeat of Archduke Charles in the War of the Spanish Succession.
Formally, the political center of the Crown of Aragon was Zaragoza, where kings were crowned at La Seo Cathedral. Leading cultural and economic centres of the Crown of Aragon were the cities of Barcelona and Valencia. Finally, Palma (Majorca) was an additional important city and seaport.
The Crown of Aragon eventually included the Kingdom of Aragon, the County of Barcelona, the Kingdom of Valencia, the Kingdom of Majorca, the Kingdom of Sicily, Malta, the Kingdom of Naples and Kingdom of Sardinia. For brief periods the Crown of Aragon also controlled Montpellier, Provence, Corsica, the Duchy of Neopatria in Latin Greece and the Duchy of Athens.
The countries that are today known as Spain and Portugal spent the Middle Ages after 722 in an intermittent struggle called the Reconquista. This struggle pitted the northern Christian kingdoms against the Islamic taifa petty kingdoms of the South and against each other.
In the Late Middle Ages, the expansion of the Aragonese Crown southwards met with the Castilian advance eastward in the region of Murcia. Afterward, the Aragonese Crown focused on the Mediterranean, acting as far as Greece and Barbary, whereas Portugal, which completed its Reconquista in 1249, would focus on the Atlantic Ocean. Mercenaries from the territories in the Crown, known as almogàvers participated in the creation of this Mediterranean "empire", and later found employment in countries all across southern Europe.
The Crown of Aragon has been considered by some[who?] as an empire which ruled in the Mediterranean for hundreds of years, with the power to set rules over the entire sea (for instance, the Llibre del Consolat del Mar or Book of the Consulate of the Sea, written in Catalan, is one of the oldest compilation of maritime laws in the world). It was indeed, at its height, one of the major powers in Europe.
However, its different territories were only connected through the person of the monarch, an aspect of empire as early as Achaemenid Persia. A contemporary, the Marqués de Lozoya described the Crown of Aragon as being more like a confederacy than a centralised kingdom, let alone an empire. Nor did official documents ever refer to it as an empire (Imperium or any cognate word); instead, it was considered a dynastic union of autonomous kingdoms.
The Aragonese empire originated in 1137, when the Kingdom of Aragon and the County of Barcelona (with the County of Provence, Girona, Cerdanya, Osona and other territories) merged by dynastic union upon the marriage of Raymond Berengar IV of Barcelona and Petronilla of Aragon; their individual titles combined in the person of their son Alfonso II of Aragon, who ascended to the throne in 1162. This union respected the existing institutions and parliaments of both territories. Although the County of Barcelona had more wealth (given its position on the Mediterranean and strong family ties in Occitania), the combined state was initially known as Regno, Dominio et Corona Aragonum et Catalonie, and later as Corona Regum Aragoniae, Corona Aragonum or simply Aragon. This was due to the total loss of Catalan influence, the renunciation of the family rights of the counts of Barcelona in Occitania, and the extinction of the House of Aragon and Barcelona in 1410. Consequently the monarchs denominated themselves de Aragon, and Aragon became prominent as an Iberian kingdom linked to the House of Jiménez which ruled over Navarre (905–1234), Castile, Leon and Galicia (1035–1126) and Aragon (1035–1137).
Petronilla's father King Ramiro, "The Monk" (reigned 1134–1137) who was raised in the Saint Pons de Thomières Monastery, Viscounty of Béziers as a Benedictine monk was the youngest of three brothers. His brothers Peter I (reigned 1094–1104) and Alfonso I El Batallador (The Battler, reigned 1104–1134) had bravely fought against Castile for the hegemony in the Iberian peninsula. After the death of Alfonso I, the Aragonese nobility that campaigned close him feared being overwhelmed by the influence of Castile. And so, Ramiro was forced to leave his monastic life and proclaimed himself King of Aragon. He married Agnes, sister of the Duke of Aquitaine and betrothed his only daughter to Raymond Berengar IV of Barcelona, member of one of the most influential families in Southern Occitania. The wedding agreement provided Raymond Berengar IV the title of Princeps Aragonum and Dominator Aragonenesis (Ruler of the Kingdom and Commander of the Military) and kept the title and honors of King of Aragon to Ramiro II.
Raymond Berengar IV, the first ruler of the united dynasty, called himself Count of Barcelona and "Prince of Aragon".
Alfonso II inherited two realms and with them, two different expansion processes. The House of Jiménez looked south in a battle against Castile for the control of the Mediterranean coast in the Iberian peninsula. The House of Barcelona looked north, to its origins, Occitania where, through family ties, it had significant influence, especially in Provence and Foix.
Soon, Alfonso II of Aragon and Barcelona committed himself to conquer Valencia as the Aragonese nobility demanded. But like his father, he gave priority to the expansion and consolidation of the House of Barcelona's influence in Occitania.
Alfonso II signed the treaties of Cazorla, a multilateral treaty between Navarre, Aragón, León, Portugal, and Castile to redefine the frontiers and zones of expansion of each kingdom. Alfonso II assured Valencia by renouncing the Aragonese rights of annexing Murcia in exchange for securing the Aragonese frontier with Castile. This action should be seen as result of the aforementioned priority given over the Occitan and Catalan dominions of the Crown of Aragon.
From the 9th century, the dukes of Aquitaine, the kings of Navarre, the counts of Foix, the counts of Toulouse and the counts of Barcelona were rivals in their attempts at controlling the various pays of Occitania. And the House of Barcelona succeeded in extending its influence to the area that is now south of France through strong family ties, in the areas of the County of Provence, County of Toulouse and County of Foix. The rebellion of the Cathars or Albigensians, who rejected the authority and teachings of the Catholic Church, led to the loss of these possessions in southern France. Pope Innocent III called upon Phillip II of France to suppress the Albigensians—The Albigensian Crusade, which led to bringing Occitania firmly under the control of the King of France, and the Capetian dynasty from northern France.
Peter II of Aragon and I of Barcelona returned from the Battle of Las Navas de Tolosa in autumn 1212 to find that Simon de Montfort had conquered Toulouse, exiling the Count Raymond VI of Toulouse, who was Peter's brother-in-law and vassal. Peter's army crossed the Pyrenees and arrived at Muret where they were joined by Raymond of Foix and Raymond of Toulouse's forces, in September 1213 to confront Montfort's army. The Battle of Muret began on 12 September 1213. The Catalan, Aragonese and Occitan forces were disorganised and disintegrated under the assault of Montfort's squadrons. Peter himself was caught in the thick of fighting, and died as a result of a foolhardy act of bravado. Thus, the nobility of Toulouse, Foix and other vassals of the Crown of Aragon were defeated. The conflict concluded with the Treaty of Meaux-Paris in 1229, in which the Crown of Aragon agreed to renounce its rights over the south of Occitania with the integration of these territories into the dominions of the King of France.
King James I (13th century) returned to an era of expansion to the South, by conquering and incorporating Majorca and a good share of the Kingdom of Valencia into the Crown. With the Treaty of Corbeil (1258), which was based upon the principle of natural frontiers, French claims over Catalonia came to an end. The general principle was clear, that Catalan influence north of the Pyrenees, beyond the Roussillon, Vallespir, Conflent and Capcir, was to cease. James I had realized that wasting his forces and distracting his energies in attempts to keep a footing in France would only end in disaster. On January 1266, James I besieged and captured Murcia, then settled his own men, mostly Catalans, there; and handed Murcia over to Castile with the treaty of Cazorla.
The Kingdom of Majorca, including the counties of Cerdanya and Roussillon-Vallespir and the city of Montpellier, was held independently from 1276 to 1279 by James II of Majorca and as a vassal of the Crown of Aragon after that date, becoming a full member of the Crown of Aragon in 1344.
Valencia was finally made a new kingdom with its own institutions and not an extension of Aragón as the Aragonese noblemen had intended since even before the creation of the Crown of Aragon. The Kingdom of Valencia became the third member of the crown together with Aragon and Catalonia. Majorca's legal status was not ranked at the same level of the aforementioned three members.
In 1282, the Sicilians rose up against the second dynasty of the Angevins on the Sicilian Vespers and massacred the garrison soldiers throughout the island. Peter III responded to their call, and landed in Trapani to an enthusiastic welcome five months later. This caused Pope Martin IV to excommunicate the king, place Sicily under interdiction, and offer the kingdom of Aragon to a son of Philip III of France.
When Peter III refused to impose the Charters of Aragon in Valencia, the nobles and towns united in Zaragoza to demand a confirmation of their privileges, which the king had to accept in 1283. Thus began the Union of Aragon, which developed the power of the Justícia to mediate between the king and the Aragonese bourgeois. 
In 1297, to solve the dispute between the Anjevins and the Aragonese over Sicily, Pope Boniface VIII created ex novo a Kingdom of Sardinia and Corsica and entrusted it as a fief to the Aragonese King James II, ignoring already existing, indigenous states. In 1324, James II finally started to seize the Pisan territories in the former states of Cagliari and Gallura. In 1347 Aragon made war on the Genoese Doria and Malaspina houses, which controlled most of the lands of the former Logudoro state in north-western Sardinia, and added them to its direct domains. The Giudicato of Arborea, the only remaining independent Sardinian state, proved far more difficult to subdue. The rulers of Arborea developed the ambition to unite all of Sardinia under their rule and create a single Sardinian state, and at a certain point (1368–1388, 1392–1409) almost managed to drive the Aragonese out. The war between Arborea and Aragon was fought on and off for more than 100 years; this situation lasted until 1409, when the army of Arborea suffered a heavy defeat by the Aragonese army in the Battle of Sanluri; the capital Oristano was lost in 1410. After some years during which Arborean rulers failed to organise a successful resurgence, they sold their remaining rights for 100,000 gold florins, and by 1420 the Aragonese Kingdom of Sardinia finally extended throughout the island. The subduing of Sardinia having taken a century, Corsica, which had never been wrestled from the Genoese, was dropped from the formal title of the Kingdom.
Through the marriage of Peter IV to Maria of Sicily (1381), the Kingdom of Sicily, as well as the duchies of Athens and Neopatria, were finally implemented more fimrly into the Crown. The Greek possessions were permanently lost to Nerio I Acciaioli in 1388 and Sicily was dissociated in the hands of Martin I from 1395 to 1409, but the Kingdom of Naples was added finally in 1442 by the conquest led by Alfonso V.
The King's possessions outside of the Iberian Peninsula and Balearic Islands were ruled by proxy through local elites as petty kingdoms, rather than subjected directly to a centralised government. They were more an economic part of the Crown of Aragon than a political one.
The fact that the King was keen on settling new kingdoms instead of merely expanding the existing kingdoms was a part of a power struggle that pitted the interests of the king against those of the existing nobility. This process was also under way in most of the European states that successfully effected the transition to the Early Modern state. Thus, the new territories gained from the Moors—namely Valencia and Majorca—were usually given fueros—Catalan furs—as an instrument of self-government in order to limit the power of nobility in these new acquisitions and, at the same time, increase their allegiance to the monarchy itself. The trend in the neighbouring kingdom of Castile was quite similar, both kingdoms giving impetus to the Reconquista by granting different grades of self-government either to cities or territories, instead of placing the new territories under the direct rule of nobility.
Union with Castile
In 1410, King Martin I died without living descendants or heirs. As a result, by the Pact of Caspe, Ferdinand of Antequera from the Castilian dynasty of Trastámara, received the Crown of Aragon as Ferdinand I of Aragon.
Later, his grandson King Ferdinand II of Aragon recovered the northern Catalan counties—Roussillon and Cerdagne—which had been lost to France as well as the kingdom of Navarre, which had recently joined the Crown of Aragon but had been lost after internal dynastic disputes.
In 1469, Ferdinand married Infanta Isabella of Castile, half-sister of King Henry IV of Castile, who became Queen of Castile and León after Henry's death in 1474. Their marriage was a dynastic union which became the constituent event for the dawn of the Kingdom of Spain. At that point both the Castile and the Crown of Aragon remained distinct territories, each keeping its own traditional institutions, parliaments and laws. The process of territorial consolidation was completed when King Charles I, known as Emperor Charles V, in 1516 united all the kingdoms on the Iberian peninsula, save the Kingdoms of Portugal and the Algarve, under one monarch—his co-monarch and mother Queen Joanna I in confinement—thereby furthering the creation of the Spanish state, albeit a decentralised one.
The literary evocation of past splendour recalls correctly the great age of the 13th and 14th centuries, when Valencia, Majorca and Sicily were conquered, the population growth could be handled without social conflict, and the urban prosperity, which peaked in 1345, created the institutional and cultural achievements of the Crown. The Aragonese crown's wealth and power stagnated and its authority was steadily transferred to the new Spanish crown after that date—the demographic growth was partially offset by the expulsion of the Jews from Spain (1492), Muslims (1502) and the expulsion of the Moriscos (1609). It was unable to prevent the loss of Roussillon in 1659, the loss of Minorca and its Italian domains in 1707–1716, and the imposition of French language on Roussillon (1700) and Castilian as the language of government in all the old Aragonese Crown lands in Spain (1707–1716).
The Crown of Aragon and its institutions were abolished in 1716 only after the War of the Spanish Succession (1701–1714) by the Nueva Planta decrees, issued by Philip V of Spain. The old regime was swept away, the administration was subsumed into the Castilian administration, the lands of the Crown were united formally with those of Castile to legally form a single state, the kingdom of Spain, as it moved towards a centralized government under the new Bourbon dynasty.
Some of the nationalist movements in Spain consider the former kingdoms of the Crown of Aragon to be the foundation of their nations, the Catalan nationalist movement being the most prominent. Spanish nationalism, on the other hand, tends to place more importance on the later dynastic union with the Crown of Castile, considering it the origin of one Spanish nation.
The reprisals inflicted on the territories that had fought against Philip V in the War of Succession is given by some Valencian and Catalan nationalists as an argument against the centralism of Spanish nationalism and in favor of federalism, confederation, or even independence. Some Catalans associated their ancient privileges with their Generalitat and resistance to Castile. Because restoration of fueros was one of its tenets, Carlism won support in the lands of the Crown of Aragon during the 19th century.
The Romanticism of the 19th century Catalan Renaixença evoked a "Pyrenean realm" that corresponded more to the vision of 13th century troubadours than to the historical reality of the Crown. This vision survives today as "a nostalgic programme of politicised culture". Thus, the history of the Crown of Aragon remains a politically loaded topic in modern Spain, especially when it comes to asserting the level of independence enjoyed by constituents of the Crown, like the County of Barcelona, which is sometimes used to justify the level of autonomy (or independence) that should be enjoyed by contemporary Catalonia and other territories.
The origin of Coat of arms of the Crown of Aragon is the familiar coat of the Counts of Barcelona and Kings of Aragon. The Pennon was used exclusively by the monarchs of the Crown and was expressive of their sovereignty. James III of Majorca, vassal of the Kingdom of Aragon, used a coat of arms with four bars, as seen on the Leges Palatinae miniatures.
Aragon, Catalonia and Valencia each had a legislative body, known as the Cortes in Aragon or Corts in Catalonia and Valencia. A Diputación General was established in each, becoming known as a Generalidad in Aragon and Generalitat in Catalonia and Valencia.
During the 15-16th century the Crown's de facto capital was Naples: after Alfonso V of Aragon, also Ferdinand II of Aragon settled the capital in Naples. Alfonso, in particular, wanted to transform Naples into a real Mediterranean capital, lavishing also huge sums to embellish it further. Later the courts were itinerant until Philip II of Spain. The Spanish historian Domingo Buesa Conde has argued that Zaragoza ought to be considered the political capital, but not economic or administrative, due to the obligation of the kings to be crowned at the Seo of Zaragoza.[nb 2]

- Domingo J. Buesa Conde, in El rey de Aragón (Zaragoza, CAI, 2000:57–59. ISBN 84-95306-44-1) postulates that the Crown of Aragon's political capital of Zaragoza, though it was not the economic one, nor the administrative one, due to the court being itinerative in the 14th century, took its start from the decrees of Peter IV of Aragon establishing his coronation there.: "Pedro IV parte (...) de la aceptación de la capital del Ebro como "cabeza del Reino". [...] por eso hizo saber a sus súbditos que Mandamos que este sacrosanto sacramento de la unción sea recibido de manos del metropolitano en la ciudad de Zaragoza al tiempo que recordaba: "...y como quiera que los reyes de Aragón están obligados a recibir la unción en la ciudad de Zaragoza, que es la cabeza del Reino de Aragón, el cual reino es nuestra principal designación—esto es, apellido—y título, consideramos conveniente y razonable que, del mismo modo, en ella reciban los reyes de Aragón el honor de la coronación y las demás insignias reales, igual que vimos a los emperadores recibir la corona en la ciudad de Roma, cabeza de su imperio. Zaragoza, antigua capital del reino de Aragón, se ha convertido en la capital política de la Corona (...).
