Hinterland \Hin"ter*land`\, n. [G.; hinter behind + land land.]
   The land or region lying behind the coast district. The term
   is used esp. with reference to the so-called

   {doctrine of the hinterland}, sometimes advanced, that
      occupation of the coast supports a claim to an exclusive
      right to occupy, from time to time, the territory lying
      inland of the coast.
