Achir

Achir, a medieval city located in Algeria's Titteri Mountains, served as the first capital of the Zirid dynasty under Fatimid suzerainty in the 10th and 11th centuries CE. Founded by Ziri ibn Menad, the city was strategically positioned between the Tell plains and the Kabyle mountains, fortified by defensive walls and bastions. Significant for its impregnable nature, Achir became a hub of intellectual activity and strategic military importance. Throughout its history, the city was a focal point of power struggles, changing hands between various dynasties, including the Zirids, Zenatas, and Hammadids. The city's archaeological site reveals two distinct areas, indicative of its evolving role and significance over time. It eventually declined in prominence, with its last recorded occupation in the late 12th century.
