Elizabeth Barry's biggest influence on Restoration drama was her presentation of performing as the tragic actress. She worked in large, prestigious London theatre companies throughout her successful career: from 1675 in the Duke's Company, 1682 – 1695 in the monopoly United Company, and from 1695 onwards as a member of the actors' cooperative usually known as Betterton's Company, of which she was one of the original shareholders. Her stage career began 15 years after the first-ever professional actresses had replaced Shakespeare's boy heroines on the London stage.
