Jack the Ripper was active in London mainly in the late summer and autumn of 1888 , with most of the infamous “canonical” murders occurring between August and November of that year.

Quick Scoop

  • Historians generally place Jack the Ripper’s main killing period in 1888 , during the Victorian era in London’s East End.
  • The series of murders people most often associate with him happened roughly from 31 August 1888 to 9 November 1888.
  • Some researchers argue that possibly related attacks and murders around Whitechapel may stretch slightly before and after 1888, into 1887–1891 , but those links are debated.

In today’s true‑crime discussions and forum threads, when people ask “when was Jack the Ripper around,” they almost always mean that intense few months in 1888 when he terrorized Whitechapel.
