The war had a marked international character, as Isabella was married to Ferdinand, heir to the Crown of Aragon, while Juana was married to King Afonso V of Portugal. France also intervened, supporting Portugal in order to threaten the victory of Aragon in Italy. Despite a few initial successes by the supporters of Juana, the scarce military aggressiveness of Afonso V and the Portuguese defeat in the battle of Toro (1476) led to the disintegration of Juana's alliance between 1476 and 1477. Thereafter the conflict consisted essentially of a war between Castile and Portugal. The naval war in the Atlantic grew in importance, where the Portuguese fleets overpowered the Castilians in the struggle for the maritime access to the wealth of Guinea. The war concluded in 1479 with the signing of the Treaty of Alcáçovas, which recognized Isabella and Ferdinand as kings of Castile and granted Portugal hegemony in the Atlantic, with the exception of the Canary Islands. Juana lost her right to the throne of Castile and remained in Portugal till her death. This conflict has also been called the Second Castilian Civil War, but this name may lead to confusion with the other civil wars that have involved Castile in the 14th and 15th centuries. Some authors refer to it as the War of Portugal; however, this term clearly represents a Castilian point of view and may dismiss the legitimacy of the alliance in favour of Juana. At other times the term Peninsular War has been used, easily confused with the Peninsular War (1808–1814), part of the Napoleonic Wars. Lastly, some authors prefer the neutral expression War of 1475–1479.

Juana, born in 1462, the first and only daughter of King Henry IV of Castile, was immediately named Princess of Asturias. A rumour spread that princess Juana was not actually the daughter of King Henry, but rather of Beltrán de la Cueva, a known lover of the Queen Consort, Joan of Portugal. Juana was thus nicknamed "la Beltraneja" as a mocking reference to her assumed father. Pressure from parts of the nobility forced the King to depose her of the title and, in her place, name his half-brother Alfonso as heir in 1464. In 1465, a group of nobility assembled in Ávila and overthrew King Henry, naming Alfonso king. This led to a war that ended in 1468 with the death of 14 years old "King" Alfonso. Henry IV regained the throne, but the title of heir became disputed between Juana, his daughter, and Isabella, his half-sister. This was resolved via the Treaty of the Bulls of Guisando, which gave Isabella succession rights but constricted her marriage options. Isabella, however, secretly married in 1469 at the age of 17, ignoring her stepbrother Henry IV. Gradually the couple gained a larger number of supporters, obtaining a papal bull sanctioning their marriage from Pope Sixtus IV in 1472 and gaining the support of the powerful Mendoza family in 1473. When Henry IV died in December 1474, however, each of the two candidates for the throne were proclaimed Queen of Castile by their respective supporters. Aware of their position of weakness against Isabella's supporters, Juana's supporters proposed that the 43 year old King Afonso V of Portugal, a widower for some 20 years, marry Juana, his niece, in order to become King Consort of Castile. International alliances Western Europe in 1470. The Kingdom of France and the Crown of Aragon maintained a long-held rivalry for the control of Roussillon and, more recently, for hegemony in Italy. In June 1474, French troops invaded Roussillon and the Aragonese were forced to retreat. Ferdinand, King only after 1479, intervened before his father John II so that he would not declare war of France, enabling him to concentrate his attention on Castilian affairs. In any case, on the possibility that the heir to the throne of Aragon would also become King of Castile, Louis XI of France officially positioned himself on the side of Juana and Portugal on September 1475. France was simultaneously at war with the Duchy of Burgundy. This made Burgundy into theoretical allies of Isabella's supporters, but in practice continued the war on their own account without coordinating their actions with the Isabella alliance. England was also briefly at war with France with the disembarkation of King Edward IV in Calais on June 1475, but through a quick diplomatic response, Louis negotiated peace with Edward and signed the Treaty of Picquigny on August. The King of England accepted a truce of nine years in exchange for a significant economic compensation and returned to England.[1] The Kingdom of Navarre was experiencing an intermittent civil war, a conflict superposed over which the French and Aragonese attempts to control the Kingdom. Lastly, the Muslim Kingdom of Granada remained neutral, despite the Portuguese efforts to draw them into the war. Rivalry between Castile and Portugal in the Atlantic Modern reconstruction of a Portuguese caravel. See also: History of Portugal (1415–1542) Throughout the 15th century, merchants, explorers and fishermen of Portugal and Castile had been penetrating further into the Atlantic Ocean. The possession of the Canary Islands was from its beginning a point of contention between the two Crowns. Later on, the control of commerce between the territories of Guinea and Elmina, rich in gold and slaves, grew to a dispute of even greater importance. During the first half of the century Castile staged the conquest of a few of the Canary Islands (Lanzarote, Fuerteventura, Hierro and Gomera) through feudal pacts, first with Norman knights and later with Castilian nobles. Portugal maintained its opposition to Castilian authority in the islands and on its part continued advancing the exploration of Guinea, obtaining significant commercial benefits. Beginning in 1452 Pope Nicholas V and his successor Calixtus III modified the previous policy of neutrality of the Holy See and issued a series of bulls favourable to Portugal, giving the Kingdom commercial control and ample religious authority in the area "until all of Guinea" and "further beyond". The Holy See did not arbitrate the question of the Canaries, whose conquest had been left relatively suspended. The King of Portugal adopted a freer commercial policy, allowing foreign subjects to trade on the African coasts in exchange for the corresponding taxes. Thus, the only one negatively affected was the King of Castile. On August 1475, after the start of the war, Isabella claimed that "the parts of Africa and Guinea" belonged to Castile by right and incited Castilian merchants to sail to them, thus initiating the naval war in the Atlantic. The conflict Sides of the War in 1475 In favour of Juana: Portugal France A part of the high Castilian nobility: and descendants of Portuguese families settled in Castile after 1385: the Archbishop of Toledo (Alfonso Carrillo de Acuña), the Estúñiga family with land bordering Portugal and navarrese ancestors, the Marquis of Villena (Diego López Pacheco), the Marquis of Cádiz (Rodrigo Ponce de León),[2] and the Grandmaster of the Order of Calatrava (Rodrigo Téllez Girón), also of Portuguese settlers in Castile since about 1385.[3] In favour of Isabella: The Crown of Aragon The rest of the Castilian nobility: the powerful Mendoza family, the Manrique de Lara family, the Duque of Medina Sidonia (Enrique Pérez de Guzmán), Beltrán de la Cueva, the Order of Santiago and the Order of Calatrava except its Grandmaster, cited above.[3] The Duchy of Burgundy and the Kingdom of England were at war with France in 1475, but did not coordinate their actions with the supporters of Isabella and are thus not normally considered part of the Isabella alliance. The fight for the throne (May 1475 – September 1476) Afonso V enters Castile A Portuguese army entered the territory of the Crown of Castile under the command of Afonso V on May 10, 1475, and advanced to Plasencia, where Juana was expecting him.[4] In that city Juana and Afonso were proclaimed Kings of Castile on May 25 and were married, although the marriage was left expecting a Papal dispensation, which they obtained a few months later. From there they marched on to Arévalo, with the intention of heading towards Burgos. The castle of Burgos and the cities of Plasencia and Arévalo were controlled by the Estúñiga family, supporters of Juana, although the actual city of Burgos, namely, the Fernandez de Velasco family backed Isabella. From there Afonso hoped to be able to unite with any troops sent by his ally Louis XI of France. However, Afonso found in Castile less supporters than he expected and changed his plans, preferring to instead consolidate his control in the area closest to Portugal, in particular Toro, a city that received him favourably even though the garrison of the castle proclaimed itself loyal to Isabella. Zamora and other Leonese villages of the lower Douro also accepted the Portuguese King. In la Mancha, Rodrigo Tellez-Giron, the Master of the Order of Calatrava, supporter of Juana, conquered Ciudad Real, but the treasurer of that same Order and the Master of the Order of Santiago (Rodrigo Manrique) reconquered the city for the Isabella side.[5] Prince Ferdinand concentrated an army in Tordesillas, and on July 15 ordered it to march to seek an encounter with Afonso. Four days later he arrived at Toro where the Portuguese King avoided a direct combat and Prince Ferdinand, lacking the necessary resources for a prolonged siege, was forced to return to Tordesillas and disband his army. The castle of Toro surrendered to Afonso V, who nevertheless, did not take the advantage to march on Burgos but instead returned to Arévalo to wait for the expected French intervention. The Count of Benavente (Rodrigo Alfonso Pimentel), supporter of Isabella, situated himself with a small force in Baltanás to monitor the Portuguese. He was attacked on November 18, 1475, was defeated and imprisoned after an intense resistance. Even though this victory opened the way to Burgos, Afonso V decided once again to withdraw to Zamora. The lack of aggressiveness of the Portuguese King debilitated the Juana alliance in Castile, which began to disintegrate.[6] Isabellian counter-attack Supporters of Isabella counter-attacked by taking Trujillo and gaining control of the lands of the Order of Alcantara, a significant portion of those of the Order of Calatrava and of the Marquisate of Villena. On December 4, a part of the garrison in Zamora rebelled against King Afonso, who was forced to flee to Toro. The Portuguese garrison maintained control of the castle, but the city received Prince Ferdinand the following day. On January 1476 the castle of Burgos surrendered to Isabella through a pact that avoided reprisals against the defeated. The Battle of Toro Castle of Zamora. Main article: Battle of Toro On February 1476, the Portuguese army, reinforced by troops brought by Prince John, son of Afonso V, left its base in Toro and surrounded Ferdinand in Zamora. However, the siege took a harder toll on the Portuguese than on those under siege due to the Castilian winter, and thus on March 1 Afonso V withdrew back towards Toro. Ferdinand's troops launched themselves in their pursuit and caught up to them one league (approximately 5 kilometres) of the aforementioned city,[7] forcing him into combat. After three hours of fighting, interrupted by the rain and nightfall, the Portuguese King withdrew to Castronuño with part of his troops while his son John, later King , John II of Portugal, from 1481 to 1496, remained near Toro, retreating with his army in an organized fashion towards the city walls and even taking a few enemy prisoners.[6] From a strictly military point of view the battle has been considered a tie or, at most, a marginal victory for the Isabella supporters. Publicists from both sides claimed victory. However, politically the battle was decisive because subsequently the bulk of the Portuguese troops retreated back to Portugal along with Juana, whose side was thus left almost totally abandoned in Castile.[8] War at sea One of the objectives of Isabella and Ferdinand in the war was to challenge Portugal's monopoly on the rich Atlantic territories that it controlled. The gold and the slaves of Guinea furthermore constituted an important source of income with which to finance the war, for which expeditions to Guinea became a priority for both belligerent sides. Portuguese ships had transversed the Andalusian coast apprehending fishing and merchant ships since the start of the war. In order to put an end to this situation, Isabella and Ferdinand sent four galleys under the command of Álvaro de la Nava, who managed to stop the Portuguese incursions and was even able to plunder the Portuguese city of Alcoutim on the Guadiana river.[9] On their part, sailors from Palos launched themselves in the pillage of the coasts of Guinea. Alfonso de Palencia, official chronicler of Isabella, narrates an expedition in which two caravels of the aforementioned port captured 120 Africans and sold them as slaves. Despite the protests by the monarchs, shortly afterwards another fleet of three caravels brought with it a captive African king along with 140 nobles of his village.[10] On May 1476 Isabella ordered the liberation of the "King of Guinea" and of his entourage.[11] The order was followed only partly, as the king was liberated and return to Guinea a few months afterwards but his companions were all sold as slaves.[11] In 1476 a Portuguese fleet of twenty ships commanded by Fernão Gomes set sail towards Guinea to regain control of it.[12] The Kings of Castile ordered the preparation of a fleet to apprehend the Portuguese and appointed Carlos de Valera in command.[7] He had numerous problems in preparing the expedition, according to Palencia because of his being opposed by the Marquis of Cadiz, the Duke of Medina Sidonia and the Estuñiga family.[13] The preparations were also delayed by a naval battle that occurred when the Castilians got knowledge that one or two Portuguese ships with a rich load had left the Mediterranean headed for Portugal and were waiting for the pirate Alvar Méndez, who was coming to escort them.[14] A fleet captained by Carlos de Valera and Andrés Sonier and composed of five galleys and five caravels intercepted them in Sanlucar de Barrameda, obtaining a victory after a hard-fought battle.[15] When Valera managed to join three Basque ships and nine Andalusian caravels[16] (25 caravels according to Palencia), all heavily armed, he no longer had any possibility of intercepting the Portuguese fleet, and decided, after stopping at Porto Santo Island, to head towards the island of António Noli in the Cape Verde archipelago, near the coast of Guinea. They plundered the island and captured António Noli, who at the time held his territory feudally from the King of Portugal. Subsequently they set sail towards the coast of Africa, where they captured two caravels owned by the Marquis of Cadiz, containing a shipment of 500 slaves. Following this, the sailors from Palos separated themselves from the expedition, which forced Valera to return to Andalusia as they were the most knowledgeable in the maritime navigation of Guinea.[13] This expedition obtained few economic benefits, as a significant portion of the slaves was returned to the Marquis of Cadiz and because Valera was forced to indemnify the Duke of Medina Sidonia for the damages caused on the Island of Noli, which the Duke claimed as his.[13] French intervention Louis XI of France. On September 23 of 1475 Louis XI of France signed a treaty of alliance with Afonso V of Portugal.[1] Between March and June of 1476 French troops captained by Alain I of Albret forcefully tried to pass through the strategic frontier locality of Fuenterrabía but were repelled. Ferdinand took advantage of the situation to secure his position in the unsettled Kingdom of Navarre. In August negotiations began in Tudela which culminated in the signing of an accord by which the belligerent parties of the Navarrese Civil War put an end to the conflict and Ferdinand obtained for Castile the control of Viana, Puente la Reina and other strongholds, as well as the right to maintain a garrison of 150 lances in Pamplona. In this way Castile strengthened itself militarily against a possible French penetration into Navarre.[17] On August 1476 Afonso V of Portugal departed towards France after signing a truce with Isabella and Ferdinand. There he tried to convince Louis XI to involve France to a greater extent in the war, but he refused this proposal on the grounds that he was focused on defeating his main enemy, Charles the Bold, Duke of Burgundy. Battle of Cabo São Vicente The King of France had sent the fleet of Norman pirate Guillaume Coullon as aid to Portugal. When on August 1476 King Afonso departed towards France, he simultaneously sent two Portuguese galleys loaded with soldiers along with the 11 ships of Coullon to come in the aid of the castle of Ceuta. On the way, on August 7, this fleet encountered five armed merchant ships from Cadiz heading for England: three Genoese carracks, a galley and a Flemish vessel. Coullon attempted to capture the merchants through a ploy, but failed and was forced to engage in an intense combat in which the Franco-Portuguese side emerged victorious. However, due to the use of incendiary weapons on the French part, a fire that erupted razed two Genoese ships and the Flemish vessel but also burned down two Portuguese galleys and two of Coullon's ships. According to Palencia, some 2,500 French and Portuguese died in the event.[18] Consolidation of Isabella and Ferdinand (September 1476 – January 1479) After their strategic victory at the battle of Toro, the repulsion of the French attack and the solicited truce by Afonso V, Isabella and Ferdinand were left in a powerful position for the throne of Castile. The nobles of the Juana alliance were forced to accept the circumstances and gradually pledged allegiance to Isabella and Ferdinand. The war was reduced to skirmishes along the Portuguese border and, above all, the continuation of the naval war for the control of the Atlantic commerce. Submission of the Juana alliance to Isabella and Ferdinand Throughout 1476 the main supporters of Juana from the nobility gradually submitted to the monarchs, in particular those from the Pacheco-Girón lineage: Juan Téllez Girón and his brother Rodrigo, Luis de Portocarrero and, in September, the Marquis of Villena.[5] On November 1476 Isabella's troops captured the castle of Toro. In the following months the couple took control of the last bordering localities controlled by the Portuguese and dealt with their adversaries in Extremadura. On July 1477 Isabella arrived at Seville, the most populous city of Castile, with the objective of assenting her power over the nobility of Andalusia. On April 1476 the Monarchs gave their first exculpation to the Marquis of Cadiz, who had been regaining power while his rival, the Duke of Medina Sidonia, initially the main Isabella supporter in Andalusia, had been falling into dishonour to the Monarchs.[4] Through skilful negotiations, the Queen managed to take control of the main strongholds of Seville occupied likewise by the Marquis and the Duke and, instead of returning them to their legitimate owners, named as their heads persons of her trust. She also prohibited the entrance to the city of Seville for both nobles, under the pretext that their simultaneous presence there would risk violent conflicts.[4] In this way the political dominance that the Duke had exercised over Seville disappeared, and the city passed on to be firmly controlled by the Crown. One of the few nobles that refused to submit to the monarchs was Marshall Fernán Arias de Saavedra. His Utrera fortress underwent an extended siege by Isabella's troops and was conquered by assault on March 1478. The defeated suffered harsh repression.[4] The first son of the monarchs, Juan of Aragon and Castile, was born in Seville on June 30, 1478, opening new perspectives on the dynastic stability of the Isabellian side. Return of Afonso V After his diplomatic failure in France, Afonso V decided to return to Portugal. On his arrival on October 1477 he found that his son, John, had proclaimed himself King. However, John happily received the return of his father and returned the Crown to him immediately.[19] Expeditions to Guinea and the Canary Islands of 1478 Main article: Battle of Guinea In 1477 a fleet departed from Andalusia headed for Guinea, although the facts about this fleet are scarce.[16] At the beginning of 1478 the monarchs prepared two new expeditions in the port of Sanlúcar de Barrameda, one directed towards Elmina and the other directed towards the conquest of the island of Grand Canary, with a total of at least 35 ships. Prince John of Portugal, aware of the Castilian plans, prepared an armada to surprise his enemies in the Canary Islands. The majority of the Castilian fleet at Grand Canary had not yet disembarked most of its troops when notice that a Portuguese squadron was approaching arrived. The Castilian fleet immediately set sail, leaving only 300 Castilian soldiers on land, who despite their reduced number managed to prevent a Portuguese disembarkation. However, this detachment was insufficient to conquer the island and was left inactive until Castilian reinforcements arrived on the island the year after.[20] The other Castilian fleet arrived at Elmina and obtained sizeable quantities of gold. However, under the orders of the commercial representative of the Crown, the fleet remained stationed there for a few months, giving time for the Portuguese fleet to arrive. The Castilians were attacked by surprise, and were subsequently defeated and taken as prisoners to Lisbon. According to Hernando del Pulgar, the income thereby obtained for King Afonso allowed him to relaunch the war on land against Castile.[21] Portuguese sources affirm that both the prisoners and a significant portion of the captured gold were returned to Castile after the signing of peace in 1479.[22] Peace between Castile and France Towards the end of 1478, before the notice of the defeat at Elmina arrived in Castile, an embassy from King Louis XI of France presented itself at the court of the monarchs, offering a peace treaty. The accord was signed in Guadalupe and included the following clauses:[23] Louis XI recognized Isabella and Ferdinand as Monarchs of Castile and León. Ferdinand agrees to break his alliance with Maximilian I, Duke of Burgundy. Both parties agree to the arbitration of affairs relative to Roussillon. Final phases (January – September 1479) Towards the end of 1478 some of the main members of the nobility supportive of Juana had again revolted in Extremadura, La Mancha (Marquis of Villena) and Galicia. The Portuguese, reinforced by the naval victory at Guinea, once again intervened in Castile in aid of their allies. Portuguese offensive Aragonese helmet circa 1470. On February 1479 a Portuguese army commanded by Garcia de Meneses, Bishop of Évora, penetrated into Extremadura. His objective was to occupy and reinforce the strongholds of Mérida and Medellín, controlled by Beatriz Pacheco, Countess of Medellin and supporter of Afonso V. According to Palencia, the Portuguese army was composed of about 1000 Knights (among which 250 Castilians were included) plus the infantry. 180 Knights of the Order of Santiago marched alongside him, commanded by their treasurer Alfonso de Monroy. On February 24, near the hill of Albuera, the aforementioned army was challenged by Isabellian forces commanded by Alonso de Cárdenas, Master of the Order of Santiago: some 500 Knights of the Order, 400 Knights of the Hermandad (mainly from Seville) and some 100 infantrymen. The battle was heavily contested. The Isabellian infantry suffered a severe blow from the Juanist cavalry and became disorganized, but the intervention of the Master of Santiago aided the panicked infantry and, at the end, the Portuguese were forced to retreat, leaving significant spoils of war on the battlefield, as well as around 85 dead Knights. Only 15 Isabellian Knights were killed.[24] Despite Isabella's victory at Albuera, the bulk of the Portuguese army was able to take refuge in Mérida and from there continue its march to Medellín, which they occupied, by which the Portuguese managed to achieve the two main objectives of their offensive. Supporters of King Ferdinand, on their part, placed both Medellín and Mérida under siege. The Pope switches sides The nuncio Jacobo Rondón de Seseña arrived at Castile with notice that Pope Sixtus IV had reversed himself and had annulled the dispensation previously awarded to Afonso V for his marriage with his niece Juana. This gravely debilitated the legitimacy of the Juanist side and the pretension of the Portuguese King to the throne of Castile. Last Castilian initiatives at sea Despite the naval defeat of 1478 at Guinea, on February 1479 the monarchs tried to organize a new fleet of about twenty caravels to expel the Portuguese from Elmina.[25] However, they were unable to gather the necessary ships, and afterwards no expeditions of importance were launched up until the peace agreement with Portugal. Peace conversations On April 1479 King Ferdinand arrived at Alcántara to participate in peace conversations promoted by Princess Beatriz, daughter of Afonso V and aunt of Isabella of Castile. The negotiations lasted 50 days but in the end no agreement was reached. The two sides continued the conflict, trying to better their respective positions in anticipation of a new peace negotiation. Isabella and Ferdinand launched an offensive against Alfonso Carrillo de Acuña, Archbishop of Toledo, who was forced to surrender, and which allowed the monarchs to challenge the Marquis of Villena. Meanwhile, the Portuguese garrisons in Extremadura successfully resisted the Castilian siege. Peace negotiations were restarted in the summer and an agreement was reached. The Peace Treaty Main article: Treaty of Alcáçovas Treaty of Alcáçovas. The treaty that put an end to the war was signed in the Portuguese city of Alcáçovas on September 4, 1479. The agreement was ratified by the King of Portugal on September 8, 1479 and by the Monarchs of Castile and Aragon in Toledo on March 6, 1480, for which the treaty is also known as the Treaty of Alcáçovas-Toledo. By this agreement, Afonso V renounced his aspirations to the throne of Castile while Isabella and Ferdinand in turn renounced any aspirations to the Portuguese throne. The two Crowns divided their areas of influence in the Atlantic: Portugal gained control of most of the territories, with the exception of the Canary Islands (of which the islands of Grand Canary, La Palma and Tenerife were yet to be conquered). Likewise two other accords were signed that resolved the question of Castilian succession. By them, Juana la Beltraneja renounced all her Castilian titles, and was given the option of either marrying the heir of Isabella and Ferdinand, Prince John, or retiring to a convent. Juana chose to do the latter, although she remained active in politics until her death. Secondly, the marriage of Princess Isabella, daughter of Isabella and Ferdinand, to the heir of the Portuguese throne, Afonso, nephew was arranged, as well as the payment by the parents of the bride of a very high dowry that in practice represented the war compensation obtained by Portugal.
