The Debatable Lands, also known as debatable ground, batable ground or threip lands, lay between Scotland and England. It was formerly in question whether the lands belonged to either the Kingdom of Scotland or the Kingdom of England, when they were still distinct kingdoms. For most of its existence, the area was a lawless zone controlled by clans of "border reivers" which terrorised the surrounding areas. It became the last part of Great Britain to be brought under state control, when King James V of Scotland partially subdued the lands in the mid-sixteenth century. The territory was eventually divided between Scotland and England.
