I puritani (The Puritans) is an opera in by Vincenzo Bellini. It was originally written in two acts and later changed to three acts on the advice of Gioachino Rossini, with whom the young composer had become friends.The music was set to a libretto by Count Carlo Pepoli. The English civil war in the 1640s has divided the land between the supporters of Parliament under Oliver Cromwell (the Roundheads) and the Royalists faithful to the Stuart monarchy (the Cavaliers). King Charles has been beheaded and Queen Enrichetta (Henrietta) has escaped in disguise.
