1197 disestablishments in Europe

Deheubarth (; , thus 'the South') was a regional name for the realms of south Wales, particularly as opposed to Gwynedd (). It is now used as a shorthand for the various realms united under the House of Dinefwr, but that Deheubarth itself was not considered a proper kingdom on the model of Gwynedd, Powys, or Dyfed is shown by its rendering in Latin as or as ("the Southern Britons") and not as a named land. In the oldest British writers, was used for all of modern Wales to distinguish it from (), the northern lands whence Cunedda originated.
