John Milton (9 December 1608 – 8 November 1674) was an English poet, polemicist, a scholarly man of letters, and a civil servant for the Commonwealth of England under Oliver Cromwell. He wrote at a time of religious flux and political upheaval, and is best known for his epic poem Paradise Lost. Milton's poetry and prose reflect deep personal convictions, a passion for freedom and self-determination, and the urgent issues and political turbulence of his day.
