Algerian.

AlgeriaNorth African country, named for Algiers, city chosen by the French as its capital when they colonized it in 1830 + Latinate "country" suffix -ia. The city name is Arabic al-Jazair, literally "the islands," in reference to four islands formerly off the coast but joined to the mainland since 1525. A resident of the place formerly was an Algerine (1650s), and the word was practically synonymous with "pirate" in English and U.S. usage early 19c.
