In the 1960s, as West End nightclub owners, the Kray twins mixed with politicians and prominent entertainers such as Diana Dors, Frank Sinatra and Judy Garland. With their gang, known as the Firm, the Krays were involved in murder, armed robbery, arson, protection rackets and assaults. Ronald ' Ronnie' Kray (24 October 1933 – 17 March 1995) and Reginald ' Reggie' Kray (24 October 1933 – 1 October 2000), identical twin brothers, were the foremost perpetrators of organised crime in the East End of London, England, from the late 1950s to 1967.
