The Seventeenth Century in England was a period of civil unrest and religious strife under King Charles I, leading to the Protectorate of Oliver Cromwell. After the restoration of the monarchy, literature flourished, especially metaphysical poetry exemplified by John Donne. Metaphysical poetry focused on philosophical and religious issues through the use of paradoxes, irony, and elaborate conceits. It also featured Cavalier lyricists who composed lighthearted poetry in support of King Charles.
