A Journal of the Plague Year is a book by Daniel Defoe, first published in March 1722. It is an account of one man's experiences of the year 1665, in which the bubonic plague struck the city of London in what became known as the Great Plague of London, the last epidemic of plague in that city. The book is told somewhat chronologically, though without sections or chapter headings, and with frequent digressions and repetitions.

Presented as an eyewitness account of the events at the time, it was written in the years just prior to the book's first publication in March 1722. Defoe was only five years old in 1665 when the Great Plague took place, and the book itself was published under the initials H. F. and is probably based on the journals of Defoe's uncle, Henry Foe, who, like 'H. F.', was a saddler who lived in the Whitechapel district of East London.

In the book, Defoe goes to great pains to achieve an effect of verisimilitude, identifying specific neighborhoods, streets, and even houses in which events took place. Additionally, it provides tables of casualty figures and discusses the credibility of various accounts and anecdotes received by the narrator.

The book is often compared to the actual, contemporary accounts of the plague in the diary of Samuel Pepys. Defoe's account, which appears to include much research, is far more systematic and detailed than Pepys's first-person account. (wikipedia.org)
