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, which brought revolution to English literature; (2) religious and political controversies in the late 1600s including the Popish Plot; and (3) the Glorious Revolution of 1688 that restored Protestant rule. Literature during this period became immoral and coarse, reflecting the debauchery of the court, before eventually evolving towards realism and a simpler style of expression.
