Ottoman Algeria in the context of "Barbary corsair"

The sultans of the Ottoman Empire (Turkish: Osmanlı padişahları), who were all members of the Ottoman dynasty (House of Osman), ruled over the transcontinental empire from its perceived inception in 1299 to its dissolution in 1922. At its height, the Ottoman Empire spanned an area from Hungary in the north to Yemen in the south and from Algeria in the west to Iraq in the east. Administered at first from the city of Söğüt since before 1280 and then from the city of Bursa since 1323 or 1324, the empire's capital was moved to Adrianople (now known as Edirne in English) in 1363 following its conquest by Murad I and then to Constantinople (present-day Istanbul) in 1453 following its conquest by Mehmed II.

The Ottoman Empire's early years have been the subject of varying narratives, due to the difficulty of discerning fact from legend. The empire came into existence at the end of the 13th century, and its first ruler (and the namesake of the Empire) was Osman I. According to later, often unreliable Ottoman tradition, Osman was a descendant of the Kayı tribe of the Oghuz Turks. The eponymous Ottoman dynasty he founded endured for six centuries through the reigns of 36 sultans. The Ottoman Empire disappeared as a result of the defeat of the Central Powers, with whom it had allied itself during World War I. The partitioning of the Empire by the victorious Allies and the ensuing Turkish War of Independence led to the abolition of the sultanate in 1922 and the birth of the modern Republic of Turkey in 1922.

The Barbary corsairs, 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 reference to the Berbers. Slaves in Barbary could be of many ethnicities, and of many different religions, such as Christian, Jewish, or Muslim. Their predation extended throughout the Mediterranean, south along West Africa's Atlantic seaboard and into the North Atlantic as far north as Iceland, but they primarily operated in the western Mediterranean. In addition to seizing merchant ships, they engaged in razzias, raids on European coastal towns and villages, mainly in Italy, France, Spain, and Portugal, but also in Britain and 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 Second Barbary War, also known as the U.S.–Algerian War and the Algerine War, was a brief military conflict between the United States and the North African state of Algiers in 1815.

Piracy had been rampant along the North African "Barbary" coast of the Mediterranean Sea since the 16th century. Algerian pirates and privateers intermittently preyed on American ships, with Algiers extracting annual tribute from the U.S. since 1795; the First Barbary War in the early 19th century, fought primarily against Algiers' neighbors, failed to fully stem the problem.

The Turkish Abductions (Icelandic: Tyrkjaránið [ˈtʰɪr̥caˌrauːnɪθ]) were a series of slave raids by pirates from Algier and Salé that took place in Iceland in the summer of 1627.

The adjectival label "Turkish" (Icelandic: Tyrkja) does not refer to ethnic Turks, country of Turkey or Turkic peoples in general; at the time it was a general term for all Muslims of the Mediterranean since the majority were from or subjects of the Ottoman Empire.
