Etymology

Attested (in Middle English, as legioun) around 1200, from Old French legion, from Latin legiō, legionem, from legō (“to gather, collect”); akin to legend, lecture. Doublet of León, which was borrowed from Spanish. Generalized sense of “a large number” is due to an allusive phrase in Mark 5:9, "My name is Legion, for we are many".
