The Habsburg jaw refers to the dominantly inherited trait which was present
and clearly evident in the Habsburg family. This condition manifests itself as
mandibular prognathism, jutting of the jaw and drooping of the lower lip. Charles II was
the last Habsburg ruler of Spain. Charles II was physically and mentally disabled and
died having produced no offspring. His death was followed by a chaotic period in which
various factions struggled for political power.
