What is "blanketeers"

The Blanketeers or Blanket March was a demonstration organised in Manchester in March 1817. The intention was for the participants, who were mainly Lancashire weavers, to march to London and petition the Prince Regent over the desperate state of the textile industry in Lancashire, and to protest over the recent suspension of the Habeas Corpus Act. The march was broken up violently and its leaders imprisoned. The Blanketeers formed part of a series of protests and calls for reform that culminated in the Peterloo Massacre and the Six Acts.
