Barbary corsairs

The Barbary corsairs, also known as the Barbary pirates, Ottoman corsairs, or naval mujahideen (in Muslim sources), were mainly Muslim corsairs and privateers who operated from the North African coast, known in Europe as the Barbary Coast. In addition to seizing merchant ships, they engaged in razzias—raids on European coastal towns and villages, mainly in Italy, France, Spain, and Portugal, as well as Britain, Ireland, and Iceland (commemorated as the Turkish Abductions).

While such raids began after the Muslim conquest of the Iberian Peninsula in the 710s, the terms "Barbary pirates" and "Barbary corsairs" are normally applied to the raiders active from the 16th century onwards, when the frequency and range of the slavers' attacks increased. In that period, Algiers, Tunis and Tripoli came under the sovereignty of the Ottoman Empire, either as directly administered provinces or as autonomous dependencies known as the Barbary states. Similar raids were undertaken from Salé (see Salé Rovers) and other ports in Morocco.

The raids were such a problem that coastal settlements were seldom undertaken until the 19th century. Between 1580 and 1680, corsairs were said to have captured about 850,000 people as slaves and from 1530 to 1780 as many as 1,250,000 people were enslaved according to historian Robert Davis, however these figures are disputed and have been questioned by other historians. Some of these corsairs were European outcasts and converts (renegade) such as John Ward and Zymen Danseker. Hayreddin Barbarossa and Oruç Reis, the Turkish Barbarossa brothers, who took control of Algiers on behalf of the Ottomans in the early 16th century, were also notorious corsairs. The European pirates brought advanced sailing and shipbuilding techniques to the Barbary Coast around 1600, which enabled the corsairs to extend their activities into the Atlantic Ocean. The effects of the Barbary raids peaked in the early-to-mid-17th century.

The scope of corsair activity began to diminish in the latter part of the 17th century, as the more powerful European navies started to compel the Barbary states to make peace and cease attacking their shipping. However, the ships and coasts of Christian states without such effective protection continued to suffer until the early 19th century. Between 1801 and 1815, occasional incidents occurred, including two Barbary Wars waged by the United States, Sweden and the Kingdom of Sicily against the Barbary states. Following the Napoleonic Wars and the Congress of Vienna in 1814–15, European powers agreed upon the need to suppress the Barbary corsairs entirely. The remainder of the threat was finally subdued for Europeans by the French conquest of Algeria in 1830 and continuous campaigns and colonization by the French during the mid-to-late 19th century.
