The Doriathrim (or "Eluwaith") were the major tribe of the Sindar,the original followers of Elu Thingol and the denizens of the kingdom of Doriath in Beleriand.They were the most advanced and civilized among the Umanyar. Sometimes the term Doriathrim was used analogous with Eglath, though the latter also usually incorporated the north-Elves or Mithrim and sometimes even the coastal Falathrim.
