The Société Générale Algérienne (SGA) was created in Paris on 18 May 1865, at a time of ambitious outward-oriented French business initiatives such as the Suez Company (est.

The SGA subsequently acquired vast landholdings and lent to finance mining, infrastructure and land development projects in Algeria, funded mainly by bond issuance.
This dynamic expansion resulted in financial overstretch during the downturn of the mid-1870s, which also severely impacted Crédit Foncier, the SGA's main sponsor together with Société Générale.
It expanded the SGA's previous commercial banking operations and opened new branches between 1878 and 1906 in Blida, Bougie, Mascara, Médéa, Sétif, Sidi Bel Abbès, and Souk Ahras.[1]: 216 .
By 1920, its Algerian branch network extended to Affreville (now Khemis Miliana), Aïn Beïda, Aïn Témouchent, Algiers, Aumale (now Sour El-Ghozlane), Batna, Blida, Boghari, Bône (now Annaba), Bordj Bou Arréridj, Bordj Bouira, Bordj Menaïel, Boufarik, Bougie, Colea, Constantine, Djidjelli, Guelma, Jemmapes (now Azzaba), Khenchela, Maison-Carrée (now El Harrach), Marengo (now Hadjout), Mascara, Médéa, Mostaganem, Orléansville (now Chlef), Palikao (now Tighennif), Philippeville (now Skikda), Relizane, Rio-Salado (now El Malah), Saïda, Saint-Arnaud (now El Eulma), Saint-Denis-de-Sig, Sétif, Sidi Bel Abbès, Soukahra, Tiaret, Tlemcen, and Vialar (now Tissemsilt).

In the early 1910s it complemented its long-established presence in Marseille with branches on the French Riviera in Antibes, Cannes, Menton, Nice, and Vence,[1]: 217 as well as Vichy.
