Beginning of the Invasion of Algiers: Thirty-four thousand French soldiers land 27 kilometers west of Algiers, at Sidi Ferruch.

The invasion of Algiers was a large-scale military operation by which the Kingdom of France, ruled by Charles X, invaded and conquered the Regency of Algiers. Algiers was annexed by the Ottoman Empire in 1529 after the capture of Algiers in 1529 and had been under its direct rule until 1710, when Baba Ali Chaouch achieved de facto independence from the Ottomans, though the Regency was still nominally a part of the Ottoman Empire. The Regency of Algiers elected its rulers through a parliament called the Divan of Algiers. These rulers/kings were known as Deys. The state could be best described as an elective monarchy.
