Name.
During the Middle Ages, Cachan was referred to in Medieval Latin texts as "Caticantum", later corrupted into "Cachentum", "Cachant", and then Cachan. Some understand "Caticantum" as meaning "singing of the cat", "mewing of the cat", but this is not certain. Some others see a connection with the verb "to hunt" ("captiare" in Vulgar Latin, "chacier" in Old French).
History.
Cachan was originally a hamlet within the commune of Arcueil, later renamed "Arcueil-Cachan". The commune of Cachan was created on 26 December 1922 when it seceded from the commune of "Arcueil-Cachan", which was renamed back to Arcueil.
