The Battle of Lepanto was a naval engagement that took place on 7 October 1571 when a fleet of the Holy League, a coalition of European Catholic states arranged by Pope Saint Pius V, inflicted a major defeat on the fleet of the Ottoman Empire in the Gulf of Patras. The Ottoman forces were sailing westward from their naval station in Lepanto (the Venetian name of ancient Naupactus Ναύπακτος, Ottoman İnebahtı) when they met the fleet of the Holy League which was sailing east from Messina, Sicily. The Spanish Empire and the Venetian Republic were the main powers of the coalition, as the league was largely financed by Philip II of Spain and Venice was the main contributor of ships.^[12]

In the history of naval warfare, Lepanto marks the last major engagement in the Western world to be fought almost entirely between rowing vessels,^[13] namely the galleys and galeasses which were the direct descendants of ancient trireme warships. The battle was in essence an "infantry battle on floating platforms".^[14] It was the largest naval battle in Western history since classical antiquity, involving more than 400 warships. Over the following decades, the increasing importance of the galleon and the line of battle tactic would displace the galley as the major warship of its era, marking the beginning of the "Age of Sail".

The victory of the Holy League is of great importance in the history of Europe and of the Ottoman Empire, marking the turning-point of Ottoman military expansion into the Mediterranean, although the Ottoman wars in Europe would continue for another century. It has long been compared to the Battle of Salamis, both for tactical parallels and for its crucial importance in the defense of Europe against imperial expansion.^[15] It was also of great symbolic importance in a period when Europe was torn by its own wars of religion following the Protestant Reformation. Pope Pius V instituted the feast of Our Lady of Victory, and Philip II of Spain used the victory to strengthen his position as the "Most Catholic King" and defender of Christendom against Muslim incursion.^[16] Historian Paul K. Davis writes that, "More than a military victory, Lepanto was a moral one. For decades, the Ottoman Turks had terrified Europe, and the victories of Suleiman the Magnificent caused Christian Europe serious concern. The defeat at Lepanto further exemplified the rapid deterioration of Ottoman might under Selim II, and Christians rejoiced at this setback for the Ottomans. The mystique of Ottoman power was tarnished significantly by this battle, and Christian Europe was heartened."^[17]

The Christian coalition had been promoted by Pope Pius V to rescue the Venetian colony of Famagusta on the island of Cyprus, which was being besieged by the Turks in early 1571 subsequent to the fall of Nicosia and other Venetian possessions in Cyprus in the course of 1570. On 1 August the Venetians had surrendered after being reassured that they could leave Cyprus freely. However, the Ottoman commander, Lala Kara Mustafa Pasha, who had lost some 50,000 men in the siege,^[19] broke his word, imprisoning the Venetians. On 17 August Marco Antonio Bragadin was flayed alive and his corpse hung on Mustafa's galley together with the heads of the Venetian commanders, Astorre Baglioni, Alvise Martinengo and Gianantonio Querini.

The members of the Holy League were the Republic of Venice, the Spanish Empire (including the Kingdom of Naples, the Habsburg Monarchy, the Kingdoms of Sicily and Sardinia as part of the Spanish possessions), the Papal States, the Republic of Genoa, the Duchies of Savoy, Urbino and Tuscany, the Knights Hospitaller and others.^[20]

The banner for the fleet, blessed by the Pope, reached the Kingdom of Naples (then ruled by the Philip II of Spain) on 14 August 1571. There, in the Basilica of Santa Chiara, it was solemnly consigned to John of Austria, who had been named the leader of the coalition after long discussions among the allies. The fleet moved to Sicily and, leaving Messina, reached (after several stops) the port of Viscardo in Cephalonia, where news arrived of the fall of Famagusta and of the torture inflicted by the Turks on the Venetian commander of the fortress, Marco Antonio Bragadin.

All members of the alliance viewed the Ottoman navy as a significant threat, both to the security of maritime trade in the Mediterranean Sea and to the security of continental Europe itself. Spain was the largest financial contributor, though the Spaniards preferred to preserve most of their galleys for Spain's own wars against the nearby sultanates of the Barbary Coast rather than expend its naval strength for the benefit of Venice.^[21][22] The combined Christian fleet was placed under the command of John of Austria (Don Juan de Austria) with Marcantonio Colonna as his principal deputy. The various Christian contingents met the main force, that of Venice (under Sebastiano Venier, later Doge of Venice), in July and August 1571 at Messina, Sicily.^[23]

The Christian fleet consisted of 206 galleys and six galleasses (large new galleys, developed by the Venetians, that carried substantial artillery) and was commanded by Spanish Admiral John of Austria, the illegitimate son of Emperor Charles V and half-brother of King Philip II of Spain, supported by the Spanish commanders Don Luis de Requesens y Zúñiga and Don Álvaro de Bazán, and Genoan commander Gianandrea Doria.^[25][26] The Republic of Venice contributed 109 galleys and six galleasses, 49 galleys came from the Spanish Empire (including 26 from the Kingdom of Naples, the Kingdom of Sicily and other Italian territories), 27 galleys of the Genoese fleet, seven galleys from the Papal States, five galleys from the Order of Saint Stephen and the Grand Duchy of Tuscany, three galleys each from the Duchy of Savoy and the Knights of Malta and some privately owned galleys in Spanish service. This fleet of the Christian alliance was manned by 40,000 sailors and oarsmen. In addition, it carried approximately 20,000^[27][28] fighting troops: 7,000 Spanish regular infantry of excellent quality,^[29] 7,000 Germans,^[30] 6,000 Italian mercenaries in Spanish pay, all good troops,^[30] in addition to 5,000 professional Venetian soldiers.^[31] Also, Venetian oarsmen were mainly free citizens and able to bear arms, adding to the fighting power of their ship, whereas convicts were used to row many of the galleys in other Holy League squadrons.^[32] Free oarsmen were generally acknowledged to be superior but were gradually replaced in all galley fleets (including those of Venice from 1549) during the 16th century by cheaper slaves, convicts and prisoners-of-war owing to rapidly rising costs.^[33]

Ali Pasha, the Ottoman admiral (Kapudan-i Derya), supported by the corsairs Mehmed Siroco (natively Mehmed Şuluk) of Alexandria and Uluç Ali, commanded an Ottoman force of 222 war galleys, 56 galliots and some smaller vessels. The Turks had skilled and experienced crews of sailors but were significantly deficient in their elite corps of Janissaries. The number of oarsmen was about 37,000, virtually all of them slaves,^[34] many of them Christians who had been captured in previous conquests and engagements.^[32] The Ottoman galleys were manned by 13,000 experienced sailors—generally drawn from the maritime nations of the Ottoman Empire—mainly Berbers, Greeks, Syrians and Egyptians—and 34,000 soldiers.^[35]

An advantage for the Christians was the numerical superiority in guns and cannon aboard their ships, as well as the superior quality of the Spanish infantry.^[26] It is estimated that the Christians had 1,815 guns, while the Turks had only 750 with insufficient ammunition.^[9] The Christians embarked with their much improved arquebusier and musketeer forces, while the Ottomans trusted in their greatly feared composite bowmen.^[36]

The Christian fleet started from Messina on 16 September, crossing the Adriatic and creeping along the coast, arriving at the group of rocky islets lying just north of the opening of the Gulf of Corinth on 6 October. Serious conflict had broken out between Venetian and Spanish soldiers, and Venier enraged Don Juan by hanging a Spanish soldier for impudence.^[37] Despite bad weather, the Christian ships sailed south and, on 6 October, reached the port of Sami, Cephalonia (then also called Val d'Alessandria), where they remained for a while.

Early on 7 October, they sailed toward the Gulf of Patras, where they encountered the Ottoman fleet. While neither fleet had immediate strategic resources or objectives in the gulf, both chose to engage. The Ottoman fleet had an express order from the Sultan to fight, and John of Austria found it necessary to attack in order to maintain the integrity of the expedition in the face of personal and political disagreements within the Holy League.^[38] On the morning of 7 October, after the decision to offer battle was made, the Christian fleet formed up in four divisions in a north-south line:

Two galleasses, which had side-mounted cannon, were positioned in front of each main division for the purpose, according to Miguel de Cervantes (who served on the galley Marquesa during the battle), of preventing the Turks from sneaking in small boats and sapping, sabotaging or boarding the Christian vessels. This reserve division consisted of 38 galleys—30 behind the Centre Division and four behind each wing. A scouting group was formed, from two Right Wing and six Reserve Division galleys. As the Christian fleet was slowly turning around Point Scropha, Doria's Right Division, at the offshore side, was delayed at the start of the battle and the Right's galleasses did not get into position.

The Ottoman fleet consisted of 57 galleys and two galliots on its right under Mehmed Siroco, 61 galleys and 32 galliots in the centre under Ali Pasha in the Sultana and about 63 galleys and 30 galliots in the south offshore under Uluç Ali. A small reserve consisted of eight galleys, 22 galliots and 64 fustas, behind the centre body. Ali Pasha is supposed to have told his Christian galley slaves, "If I win the battle, I promise you your liberty. If the day is yours, then God has given it to you." John of Austria, more laconically, warned his crew, "There is no paradise for cowards."^[39]

The lookout on the Real sighted the Turkish van at dawn of 7 October. Don Juan called a council of war and decided to offer battle. He travelled through his fleet in a swift sailing vessel, exhorting his officers and men to do their utmost. The Sacrament was administered to all, the galley slaves were freed from their chains, and the standard of the Holy League was raised to the truck of the flagship.^[37]

The wind was at first against the Christians, and it was feared that the Turks would be able to make contact before a line of battle could be formed. But around noon, shortly before contact, the wind shifted to favour the Christians, enabling most of the squadrons to reach their assigned position before contact. Four galeasses stationed in front of the Christian battle line opened fire at close quarters at the foremost Turkish galleys, confusing their battle array in the crucial moment of contact. Around noon, first contact was made between the squadrons of Barbarigo and Sirocco, close to the northern shore of the Gulf. Barbarigo had attempted to stay so close to the shore as to prevent Sirocco from surrounding him, but Sirocco, knowing the depth of the waters, managed to still insert galleys between Barbarigo's line and the coast. In the ensuing mêlée, the ships came so close to each other as to form an almost continuous platform of hand-to-hand fighting in which both leaders were killed. The Christian galley slaves freed from the Turkish ships were supplied with arms and joined in the fighting, turning the battle in favour of the Christian side.^[41]

Meanwhile, the centres clashed with such force that Ali Pasha's galley drove into the Real as far as the fourth rowing bench, and hand-to-hand fighting commenced around the two flagships, between the Spanish Tercio infantry and the Turkish janissaries. When the Real was nearly taken, Colonna came alongside with the bow of his galley and mounted a counter-attack. With the help of Colonna, the Turks were pushed off the Real and the Turkish flagship was boarded and swept. The entire crew of Ali Pasha's flagship was killed, including Ali Pasha himself. The banner of the Holy League was hoisted on the captured ship, breaking the morale of the Turkish galleys nearby. After two hours of fighting, the Turks were beaten left and centre, although fighting continued for another two hours.^[42] A flag taken at Lepanto by the Knights of Saint Stephen, said to be the standard of the Turkish commander, is still on display, in the Church of the seat of the Order in Pisa.^[43]

On the Christian right, the situation was different, as Doria continued sailing towards the south instead of taking his assigned position. He would explain his conduct after the battle by saying that he was trying to prevent an enveloping manoeuvre by the Turkish left. But Doria's captains were enraged, interpreting their commander's signals as a sign of treachery. When Doria had opened a wide gap with the Christian centre, Uluç Ali swung around and fell on Colonna's southern flank, with Doria too far away to interfere. Ali attacked a group of some fifteen galleys around the flagship of the Knights of Malta, threatening to break into the Christian centre and still turn the tide of the battle. This was prevented by the arrival of the reserve squadron of Santa Cruz. Uluç Ali was forced to retreat, escaping the battle with the captured flag of the Knights of Malta.^[44]

Isolated fighting continued until the evening. Even after the battle had clearly turned against the Turks, groups of janissaries kept fighting to the last. It is said that at some point the Janissaries ran out of weapons and started throwing oranges and lemons at their Christian adversaries, leading to awkward scenes of laughter among the general misery of battle.^[9] At the end of the battle, the Christians had taken 117 galleys and 20 galliots, and sunk or destroyed some 50 other ships. Around ten thousand Turks were taken prisoner, and many thousands of Christian slaves were rescued. The Christian side suffered around 7,500 deaths, the Turkish side about 30,000.^[45]

The engagement was a significant defeat for the Ottomans, who had not lost a major naval battle since the fifteenth century.^[46] However, the Holy League failed to capitalize on the victory, and while the Ottoman defeat has often been cited as the historical turning-point initiating the eventual stagnation of Ottoman territorial expansion, this was by no means an immediate consequence; even though the Christian victory at Lepanto confirmed the de facto division of the Mediterranean, with the eastern half under firm Ottoman control and the western under the Habsburgs and their Italian allies, halting the Ottoman encroachment on Italian territories, the Holy League did not regain any territories that had been lost to the Ottomans prior to Lepanto.^[47] Historian Paul K. Davis synopsizes the importance of Lepanto this way: "This Turkish defeat stopped Ottomans' expansion into the Mediterranean, thus maintaining western dominance, and confidence grew in the west that Turks, previously unstoppable, could be beaten"^[48]

The Ottomans were quick to rebuild their navy.^[49] By 1572, about six months after the defeat, more than 150 galleys, 8 galleasses, and in total 250 ships had been built, including eight of the largest capital ships ever seen in the Mediterranean.^[50] With this new fleet the Ottoman Empire was able to reassert its supremacy in the Eastern Mediterranean.^[51] Sultan Selim II's Chief Minister, the Grand Vizier Mehmed Sokullu, even boasted to the Venetian emissary Marcantonio Barbaro that the Christian triumph at Lepanto caused no lasting harm to the Ottoman Empire, while the capture of Cyprus by the Ottomans in the same year was a significant blow, saying that:

In 1572, the allied Christian fleet resumed operations and faced a renewed Ottoman navy of 200 vessels under Kılıç Ali Pasha, but the Ottoman commander actively avoided engaging the allied fleet and headed for the safety of the fortress of Modon. The arrival of the Spanish squadron of 55 ships evened the numbers on both sides and opened the opportunity for a decisive blow, but friction among the Christian leaders and the reluctance of Don Juan squandered the opportunity.^[53]

Pius V died on 1 May 1572. The diverging interests of the League members began to show, and the alliance began to unravel. In 1573, the Holy League fleet failed to sail altogether; instead, Don Juan attacked and took Tunis, only for it to be retaken by the Ottomans in 1574. Venice, fearing the loss of her Dalmatian possessions and a possible invasion of Friuli, and eager to cut her losses and resume the trade with the Ottoman Empire, initiated unilateral negotiations with the Porte.^[54]

The Holy League was disbanded with the peace treaty of 7 March 1573, which concluded the War of Cyprus. Venice was forced to accept loser's terms in spite of the victory at Lepanto. Cyprus was formally ceded to the Ottoman Empire, and Venice agreed to pay an indemnity of 300,000 ducats. In addition, the border between the two powers in Dalmatia was modified by the Turkish occupation of small but important parts of the hinterland that included the most fertile agricultural areas near the cities, with adverse effects on the economy of the Venetian cities in Dalmatia.^[55] Peace would hold between the two states until the Cretan War of 1645.^[56]

In 1574, the Ottomans retook the strategic city of Tunis from the Spanish-supported Hafsid dynasty, which had been re-installed after John of Austria's forces reconquered the city from the Ottomans the year before. Thanks to the long-standing Franco-Ottoman alliance, the Ottomans were able to resume naval activity in the western Mediterranean. In 1576, the Ottomans assisted in Abdul Malik's capture of Fez – this reinforced the Ottoman indirect conquests in Morocco that had begun under Suleiman the Magnificent. The establishment of Ottoman suzerainty over the area placed the entire southern coast of the Mediterranean from the Straits of Gibraltar to Greece under Ottoman authority, with the exceptions of the Spanish-controlled trading city of Oran and strategic settlements such as Melilla and Ceuta. But after 1580, the Ottoman Empire could no longer compete with the advances in European naval technology, especially the development of the galleon and line of battle tactics used in the Spanish Navy.^[57] Spanish success in the Mediterranean continued into the first half of the 17th century. Spanish ships attacked the Anatolian coast, defeating larger Ottoman fleets at the Battle of Cape Celidonia and the Battle of Cape Corvo. Larache and La Mamora, in the Moroccan Atlantic coast, and the island of Alhucemas, in the Mediterranean, were taken (although Larache and La Mamora were lost again later in the 17th century). Ottoman expansion in the 17th century shifted to land war with Austria on one hand, culminating in the Great Turkish War of 1683–1699, and to the war with Safavid Persia on the other.

Giovanni Pietro Contarini’s History of the Events, which occurred from the Beginning of the War Brought against the Venetians by Selim the Ottoman, to the Day of the Great and Victorious Battle against the Turks was published in 1572, a few months after Lepanto. It was the first comprehensive account of the war, and the only one to attempt a concise but complete overview of its course and the Holy League’s triumph. Contarini’s account went beyond effluent praise and mere factual reporting to examine the meaning and importance of these events. It is also the only full historical account by an immediate commentator, blending his straightforward narrative with keen and consistent reflections on the political philosophy of conflict in the context of the Ottoman-Catholic confrontation in the early modern Mediterranean.^[58]

The Holy League credited the victory to the Virgin Mary, whose intercession with God they had implored for victory through the use of the Rosary. Andrea Doria had kept a copy of the miraculous image of Our Lady of Guadalupe given to him by King Philip II of Spain in his ship's state room.^[59] Pope Pius V instituted a new Catholic feast day of Our Lady of Victory to commemorate the battle, which is now celebrated by the Catholic Church as the feast of Our Lady of the Rosary.^[60] Dominican friar Juan Lopez in his 1584 book on the rosary states that the feast of the rosary was offered "in memory and in perpetual gratitude of the miraculous victory that the Lord gave to his Christian people that day against the Turkish armada".^[61]

A piece of commemorative music composed after the victory is the motet Canticum Moysis (Song of Moses Exodus 15) Pro victoria navali contra Turcas by the Spanish composer based in Rome Fernando de las Infantas.^[62] The other piece of music is Jacobus de Kerle's "Cantio octo vocum de sacro foedere contra Turcas" 1572 (Song in Eight Voices on the Holy League Against the Turks), in the opinion of Pettitt (2006) an "exuberantly militaristic" piece celebrating the victory.^[63] There were celebrations and festivities with triumphs and pageants at Rome and Venice with Turkish slaves in chains.^[64]

Spanish poet Fernando de Herrera wrote the poem "Canción en alabanza de la divina majestad por la victoria del Señor Don Juan" in 1572. King James VI of Scotland published in 1591 a poem of about 1,000 lines celebrating this Christian victory.^[65]

The fortress of Palmanova in Italy originally called Palma was built by the Republic of Venice on 7 October 1593 to commemorate the victory.

There are many pictorial representations of the battle. Prints of the order of battle appeared in Venice and Rome in 1571,^[66] and numerous paintings were commissioned, including one in the Doge's Palace, Venice, by Andrea Vicentino on the walls of the Sala dello Scrutinio, which replaced Tintoretto's Victory of Lepanto, destroyed by fire in 1577. Titian painted the battle in the background of an allegorical work showing Philip II of Spain holding his infant son, Don Fernando, his male heir born shortly after the victory, on 4 December 1571. An angel descends from heaven bearing a palm branch with a motto for Fernando, who is held up by Philip: "Majora tibi" (may you achieve greater deeds; Fernando died as a child, in 1578).^[67]

The Allegory of the Battle of Lepanto (c. 1572, oil on canvas, 169 x 137 cm, Gallerie dell'Accademia, Venice) is a painting by Paolo Veronese. The lower half of the painting shows the events of the battle, whilst at the top a female personification of Venice is presented to the Virgin Mary, with Saint Roch, Saint Peter, Saint Justina, Saint Mark and a group of angels in attendance.

A painting by Wenceslas Cobergher, dated to the end of the 16th century, now in San Domenico Maggiore, shows what is interpreted as a victory procession in Rome on the return of admiral Colonna. On the stairs of Saint Peter's Basilica, Pius V is visible in front of a kneeling figure, identified as Marcantonio Colonna returning the standard of the Holy League to the pope. On high is the Madonna and child with victory palms.^[68]

Tommaso Dolabella painted his The Battle of Lepanto in c. 1625–1630 on the commission of Stanisław Lubomirski, commander of the Polish left wing in the Battle of Khotyn (1621). The monumental painting (3.05 m × 6.35 m) combines the Polish victory procession following this battle with the backdrop of the Battle of Lepanto. It was later owned by the Dominicans of Poznań and since 1927 has been on display in Wawel Castle, Cracow.^[69]

The Battle of Lepanto by Juan Luna (1887) is displayed at the Spanish Senate in Madrid.

The English author G. K. Chesterton wrote a poem Lepanto, first published in 1911 and republished many times since. It provides a series of poetic visions of the major characters in the battle, particularly the leader of the Christian forces, Don Juan of Austria. It closes with verses linking Miguel de Cervantes, who fought in the battle, with the "lean and foolish knight" he would later immortalize in Don Quixote. Miguel de Cervantes lost the use of an arm in this battle and therefore he is known as el manco de Lepanto (the one-armed man of Lepanto) in the Hispanic world.^[70]

Emilio Salgari devoted two of his historical novels, Capitan Tempesta ("Captain Tempest", 1905) and Il Leone di Damasco ("The Lion of Damascus", 1910), to the siege of Famagusta and the Battle of Lepanto. The novels were adapted in two films by Corrado D'Errico in 1942.^[71]
