The Barbary–Portuguese conflicts were a series of military engagements between the Kingdom of Portugal and the Barbary states of North Africa from the 16th to the 19th century.
16–17th century
Battle off Albufeira, 1554
In 1554, off the coast of Albufeira, came eight oared vessels from Algiers, commanded by the corsair Xaramet Arraes, or Cazale, Captain-Major Dom Pedro da Cunha sailed in pursuit. Upon sighting four of the enemy ships, he gave chase. The corsairs, seeing escape was impossible, turned to battle. It lasted for over two hours before Dom Pedro's forces overcame the corsairs, killing forty and capturing the commander. Meanwhile, his brother, Dom Vasco da Cunha, engaged another corsair ship, capturing it after an hour of fight. Dom Nuno da Cunha pursued two fustas, capturing one while the other escaped into the night.
In total, over two hundred corsairs were taken, along with a hundred Christian captives, who were freed from their chains. The remaining enemy ships fled.
Sack of Madeira, 1617
In 1617, Algerian forces arrived in Madeira with eight ships and 800 men. They raided the island, enslaving 1,200 of its inhabitants. During the attack, the Algerians destroyed the island's archives and looted various items, including church bells. It is also reported that they devastated the nearby island of Porto Santo in the Madeira archipelago, capturing 663 people and enslaving them.
Sinking of the Nossa Senhora da Conceição, 1621
The Nossa Senhora da Conceição was a Portuguese carrack that left Goa, India, in March 1621, heading for Lisbon with 600–800 people and 22 cannons. After passing the Azores, the captain received reports of Barbary corsairs, but reassurances came from a Portuguese fleet. On October 8, the Conceição mistook a fleet of Algerian ships for friendly vessels and was surrounded. Despite fierce resistance, the Portuguese repelled the attackers after 11 hours of battle. The next day, the ship was repaired, but on October 11, it became stranded near Ericeira. The corsairs returned, launching incendiary attacks that set the ship on fire. With the crew unable to fight back, the Portuguese surrendered. The carrack sank, and the survivors were taken as prisoners to Algiers, where most remained captive. Captain Luís de Sousa died from his injuries shortly after.
Combat near Cabo da Roca, 1669
On November 5, 1669, likely at a time when no Armada ships were patrolling the coast, two ships returning alone from Brazil engaged in combat with an Algerian frigate that had set up an ambush near Cabo da Roca. However, after the combat, the Portuguese ships managed to safely reach Lisbon.
Combat near Cabo de São Vicente, 1671
In 1671, Barbary corsairs captured a ship returning from Mazagan and attacked a small vessel (patacho) heading to India. This occurred near Cabo de São Vicente, where the patacho had sought refuge from a storm.
Capture of Portuguese ships, 1674
In 1674, the mission to patrol the coast was assigned to the frigate Nossa Senhora da Piedade. However, the vessel was reportedly lost in combat against Barbary corsairs from North Africa.
Later that year, despite the presence of naval patrols, a merchant charrua was captured by Barbary corsairs near Madeira. Its crew and passengers were taken to Algiers, where they were sold as slaves.
1675 battles
In 1675, Algerian ships attacked the island of Santa Maria in the Azores. Several inhabitants of the island were captured.
In May 1675, a Portuguese fleet composed of three galleons, three ships and a frigate, among others, patrolled the coast. This force forced two corsair ships to run aground near the coast of Algiers. Additionally, the ship Madre de Deus engaged in combat with four corsair frigates near Vigo, managing to drive them away.
However, despite Portuguese efforts, the corsairs remained highly active. A corsair vessel with 16 guns captured a merchant ship armed with 26 guns in the port of Funchal. Additionally, corsairs captured several fishermen near the mouth of the Tagus River.
Later in 1675, Portuguese ships recovered three English vessels from a group of corsairs. The ship Nossa Senhora Madre de Deus fought a three-hour battle with a corsair frigate, eventually forcing it to flee. In August, two Portuguese galleons previously mentioned engaged three corsair vessels near Cádiz, sinking one of them. Around the same time, the galleon São Francisco Xavier fought against a Muslim ship during a mission near the Azores.
Portuguese expedition to Oran, 1677
On August 1, 1677, a Portuguese naval force was assembled to relieve the city of Oran, which was under siege by Muslim forces. Although the exact actions taken by the force are unclear, it is believed they captured two enemy ships.
Combat off Tétouan, 1692
In July 1692, a Portuguese fleet intercepted a group of Algerian corsairs off Tétouan. After a combat, the Portuguese forces set one of the corsair ships on fire and captured another, rescuing a Spanish vessel in the process.
Combat near Mamora, 1694
In the summer of 1694, Portuguese frigates Nossa Senhora da Boaventura, Nossa Senhora da Penha de França, and others engaged a corsair ship from Algiers off Mamora, forcing it to run aground.

Actions of March 1714
In early March 1714, three corsair ships from Algiers attacked a Portuguese merchant ship that was coming from Brazil with a large load of sugar bound for Lisbon, between São Miguel and Lisbon. After an eight-hour battle, the corsairs eventually withdrew, and the Portuguese ship entered the Tagus River, with about 20 dead, many injured, and damage to the ship.
Later that same month, another Portuguese merchant ship, armed with 28 guns, was attacked near the Berlengas by three North African frigates, one with 50 guns, another with 40, and the last with 30. After nearly 24 hours of combat, the corsair ships eventually abandoned their target, which entered Lisbon without major issues.

Action of July 1750
Despite the presence of Portuguese warships along the coast, in late July, a ship returning from Brazil sighted two vessels off the Berlengas Islands, one of which was a captured ship, and the other an Algerian xaveco with about 300 men aboard. The corsairs attempted to board the Portuguese ship but failed, suffering heavy casualties.

One of the caravelas was lost after hitting a rock, possibly near the Berlengas.
Attacks on Lisbon, 1778
In August 1778, Algerian corsairs captured several ships off the coast of Lisbon. In response, a warship was dispatched from Lisbon to patrol the Algarve coast, and the frigate São João Baptista was put on guard duty, remaining at sea until October.
Spanish attack on Algiers, 1784
Because of the continuous activity of the North African corsairs, mainly against Spanish fleets, the kingdom was forced to carry out an attack on Algiers. Portugal participated in the operation, bringing their ships Santo António, S. José and Nossa Senhora do Bom Sucesso, commanded by Bernardo Ramires Esquível.
Combat of Tritão, 1786
On May 5, 1786, a Portuguese fleet, which included the Nossa Senhora do Bom Sucesso, Princesa do Brasil, and Cisne, conducted multiple patrols in the Strait and Mediterranean, including an action against Algerian corsairs. The Tritão, commanded by captain Manuel Ferreira Nobre, fought an Algerian ship off Gibraltar, resulting in the corsair ship getting stuck and its crew fleeing.
Action of 26 May 1789
On 26 May or early June 1789, a small Portuguese division, commanded by coronel do mar José de Melo Breyner, spotted an Algerian xebec accompanied by a captured French ship, the Le Désir, in the vicinity of Algiers. The division was constituted by the 90-gun ship of the line Nossa Senhora da Conceição, by a frigate, and by the 24-gun brigantine Lebre. The xebec was returning to its base when it was immediately attacked by the Portuguese ships, being forced to let go of his prey and flee to Algiers, where it took refuge along the coast being sheltered by the fortresses. The Lebre pursued the xebec, but after a few hours of exchanging fire, the Portuguese were unable to capture it due to shallow waters and the arrival of six reinforcements from Algiers, and ended up withdrawing. The French ship was sent to Lisbon, escorted by the Lebre, entering the Tagus on 15 or 19 June and then handed over to the consul of France. The Lebre returned to the Strait of Gibraltar on 24 June.

Both the Balão and the captured xebec entered Lisbon on April 9, 1800.

After a combat of approximately 90 minutes, the frigate Cisne was eventually captured.
