Roundheads
Roundheads was the name bestowed in the Civil War by the Royalists upon the Parliamentary troops, in reference to the closely-cropped hair which contrasted strongly with the long locks of the Royalists. The equivalent tetc-ronde is still applied as a term of reproach in one part of Europe to signify a racial and religious difference, the people so called terming their opponents tetc-carrec or square-heads.
