Algiers
capital city of Algeria
Algiers ( al-JEERZ; Arabic: الجزائر, romanized: al-Jazāʾir, pronounced [al.d͡ʒazaːʔir] , locally [(ɪ)ˈd͡ːzaːjir]; French: Alger, pronounced [alʒe] ; Algerian Tamazight: ⴷⵣⴰⵢⵔ, romanized: Dzayer), officially Capital City of Algiers (Arabic: الجزائر العاصمة, romanized: al-Jazāʾir al-ʿĀṣima; Algerian Tamazight: ⴷⵣⴰⵢⵔ ⵜⴰⵎⴰⵏⴰⵖⵜ, romanized: Dzayer Tamaneɣt), is the capital and largest city of Algeria, located on the Mediterranean Sea in the north-central portion of the country. In 2025, an estimated 4.325 million people resided within the urban area. Algiers is the third-largest city on the Mediterranean, the tenth-largest city in the Arab world, and the 19th-largest city in Africa by population. Algiers is the capital of the Algiers Province; it extends over many communes without having its own separate governing body. It extends along the Bay of Algiers surrounded by the Mitidja Plain and major mountain ranges. Its favorable location made it the center of Ottoman and French influences for the region, shaping it to be a diverse metropolis.
Algiers was formally founded in 972 AD by Buluggin ibn Ziri, though its history goes back to between 1200 and 250 BC as a Phoenician trading settlement. Over time, it came under the control of several powers, including Numidia, the Roman Empire, and various Islamic caliphates. In 1516, it became the capital of the Ottoman Regency of Algiers, a status it held until the French invasion in 1830, after which it served as the capital of French Algeria. During World War II, it briefly functioned as the administrative center of Free France from 1942 to 1944 before returning to French colonial rule.

Why this record matters
“Algiers” is worth following because a concise public description often conceals a longer documentary argument. Here, Algiers, capital and city provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q3561. VIAF identifies the subject as 155624247. The Library of Congress control number is n79058668. Authority coordinates are 36.776, 3.059. 1 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2025, 1200, 1516 and 1830.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
