The Rover or The Banish'd Cavaliers is a play in two parts written by the English author Aphra Behn. It was a very popular Restoration comedy.
Behn had famously worked as a spy for Charles II against the Dutch. However, Charles was slow to pay her for her services and slow to meet his promises, if he ever paid her at all, and Behn sought to make money first with her poetry, and then with plays and novels. The Rover appeared on the stage in 1677, and it was popular enough that a second part appeared in 1681. The play appeared for a long run, enabling Behn to make a fair income from it (the author received the proceeds from the box office every third night the play ran).
