The document discusses three key historical events that influenced literature during the age of Dryden: (1) the restoration of Charles II to the English throne in 1660, (2) the religious and political controversies of the time including the Popish Plot, and (3) the Glorious Revolution of 1688. It then describes how literature changed after the restoration, with writers abandoning old standards and imitating immoral French works, leading to a period of vulgar realism and formalism in English literature.
