Pepys' diary provides a first-hand account of the Restoration, and it is also notable for its detailed accounts of several major events of the 1660s, along with the lesser known diary of John Evelyn.

S. Knighton has written: "From its reporting of these two disasters to the metropolis in which he thrived, Pepys's diary has become a national monument."
