Deyrah, or Dehra. A town of Northern Hindostan, and the principal place of the British province designated the Deyrah Doon. During the Nepaul war in 1815, the Deyrah Doon became the scene of military operations, and acquired a mournful celebrity by the obstinate defense made by the Goorkhas at Kalunga, or Nalapani, in the siege of which the British lost a considerable number of men, including their gallant commander, Gen. Gillespie.

Diarbekir. A city of Asiatic Turkey, and capital of the pashalic of Diarbekir. This place was successively taken, retaken, and destroyed, in the ancient wars between the Persians and Romans. It was pillaged by Tamerlane in the year 1393; and was successively taken and retaken by the Persian kings, until it was conquered by Selim, the first sultan of the Osmanli Turks, in the year 1515.

Dictator. In the earliest times, was the name of the highest magistrate of the Latin Confederation, and in some of the Latin towns the title was continued long after these towns were subjected to the dominion of Rome. In the Roman republic the dictator was an extraordinary magistrate, irresponsible and endowed with absolute authority. The dictatorship could not lawfully be held longer than six months. Dictators were only appointed so long as the Romans had to carry on wars in and out of Italy, or when any vigorous measure had to be acted upon. The limits of his power were as follows: he could not touch the treasury; he could not leave Italy; and he could not ride through Rome on horseback without previously obtaining the permission of the people.
