Camp follower is a term used to identify civilians and their children who follow armies. There are two common types of camp followers; first, the wives and children of soldiers, who follow their spouse or parent's army from place to place; the second type of camp followers have historically been informal army service providers, servicing the needs of encamped soldiers, in particular selling goods or services that the military does not supply—these have included cooking, laundering, liquor, nursing, sexual services and sutlery.
