“[O]ne of the first actions undertaken by the French army after it conquest of Algiers in 1830 is the ‘administrativization’ of the old city, the dense and labyrinthine Casbah. They thus name the streets — the imaginaries of these names is also a colonial enterprise — and attributes a number to each house. Such an administrative and military process allows the association of identities to urban location, and thus a more thorough policing.”
