A DOCUMENT signed by Oliver Cromwell has been found by Barnsley archives.
Archivists discovered a petition sent to Cromwell in 1654 by Yorkshire landowner John Savile.
The document was part of a collection of old family papers transferred to the council from archives in Sheffield.
At the bottom of the document Cromwell instructs that Savile's claim should be looked into, and he signs the paper as "Oliver P".
Paul Stebbing of Barnsley Archives and Local Studies said: "We are delighted to have an original document from an important period in British history amongst our collections, especially one signed by such a key figure."
