Jack the Ripper: The first of 11 unsolved brutal murders of women committed in or near the impoverished Whitechapel district in the East End of London, occurs.

Jack the Ripper was an unidentified serial killer who was active in and around the impoverished Whitechapel district of London, England, in 1888. In both criminal case files and the contemporaneous journalistic accounts, the killer was also called the Whitechapel Murderer and Leather Apron.

The Whitechapel murders were committed in or near the impoverished Whitechapel district in the East End of London between 3 April 1888 and 13 February 1891. At various points some or all of these eleven unsolved murders of women have been ascribed to the notorious unidentified serial killer known as Jack the Ripper.

Whitechapel is an area in the London Borough of Tower Hamlets, London, England. It is in east London and part of the East End. It is the location of Tower Hamlets Town Hall and, therefore, the borough town centre. Whitechapel is 3.4 miles (5.5 km) east of Charing Cross.

The East End of London, often referred to within the London area simply as the East End, is the historic core of wider East London, east of the Roman and medieval walls of the City of London and north of the River Thames. It does not have universally accepted boundaries on its northern and eastern sides, though the River Lea is sometimes seen as the easternmost boundary. Parts of it may be regarded as lying within Central London. The term "East of Aldgate Pump" is sometimes used as a synonym for the area.
