Following the French capture of Algeria (1833), that region saw several waves of Catalan-speaking settlers. People from the Spanish Alacant province settled around Oran, whereas Algiers received immigration from Northern Catalonia and Minorca. Their speech was known as patuet. By 1911, the number of Catalan speakers was around 100,000. After the declaration of independence of Algeria in 1962, almost all the Catalan speakers fled to Northern Catalonia (as Pieds-Noirs) or Alacant.
