The secret service department: a British Intelligence Bureau in mid-Victorian London,September 1867 to April 1868

In December 1867 the Earl of Derby's government established a ‘Secret Service Department’ in London to extend Dublin Castle's anti- Fenian intelligence network to England and to contend with the perceived threat posed by domestic and international secret societies. This secret detective force – an early English intelligence bureau – lasted only until April 1868, but its disbandment reflected practical and administrative difficulties rather than a pervading prejudice towards spying. Indeed, the motivations for founding the department and the actions of those involved suggest that long before the establishment of the Special Branch in the 1880s, need rather than principle determined official actions in regard to political espionage.
