The play is nominally set in the early 1400s, during the same period as the Henry IV plays featuring Falstaff, but there is only one brief reference to this period, a line in which the character Fenton is said to have been one of Prince Hal's rowdy friends (he "kept company with the wild prince and Poins"). In all other respects, the play implies a contemporary setting of the Elizabethan era, circa 1600.

The Merry Wives of Windsor is a comedy by William Shakespeare, first published in 1602, though believed to have been written prior to 1597. The Windsor of the play's title is a reference to Windsor Castle in Berkshire, England, and though nominally set in the reign of Henry IV, the play makes no pretence to exist outside contemporary Elizabethan era English middle class life. It features the character Sir John Falstaff, the fat knight who had previously been featured in Henry IV Parts 1 and 2. It has been adapted for the opera on several occasions.

William Shakespeare ( 26 April 1564—23 April 1616) was an English poet, playwright, and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon". His extant works, including some collaborations, consist of around 38 plays, 154 sonnets, two long narrative poems, and a few other verses, of which the authorship of some is uncertain. His plays have been translated into every major living language and are performed more often than those of any other playwright.
