History of Algeria

ured the island of Ischia, taking 4,000 prisoners, and enslaved some 9,000 inhabitants of Lipari, almost the entire population. In 1551, Turgut Reis enslaved the entire population of the Maltese island of Gozo, between 5,000 and 6,000, sending them to Libya. In 1554, pirates sacked Vieste in southern Italy and took an estimated 7,000 slaves.
In 1558, Barbary corsairs captured the town of Ciutadella (Minorca), destroyed it, slaughtered the inhabitants and took 3,000 survivors to Istanbul as slaves. In 1563, Turgut Reis landed on the shores of the province of Granada, Spain, and captured coastal settlements in the area, such as Almuñécar, along with 4,000 prisoners. Barbary pirates often attacked the Balearic Islands, and in response many coastal watchtowers and fortified churches were erected. The threat was so severe that the island of Formentera became uninhabited.
Between 1609 to 1616, England lost 466 merchant ships to Barbary pirates. In the 19th century, Barbary pirates would capture ships and enslave the crew. Later American ships were attacked. During this period, the pirates forged affiliations with Caribbean powers, paying a "license tax" in exchange for safe harbor of their vessels. One American slave reported that the Algerians had enslaved 130 American seamen in the Mediterranean and Atlantic from 1785 to 1793.
Plague had repeatedly struck the cities of North Africa. Algiers lost from 30,000 to 50,000 inhabitants to the plague in 1620–21, and again in 1654–57, 1665, 1691, and 1740–42.
Relations with the US
US ships paid the tribute demanded by the rulers of Algiers, Tunis, Tripoli and Morocco, preventing attacks on their shipping by Mediterranean corsairs, no longer covered by Great Britain after independence. In 1794, US Congress voted for funds appropriation for warship construction, to counter Mediterranean threats. Despite this the US signed a treaty of $10M (20% of the US annual
