Angmar (Sindarin: 'Iron-home'; pronounced [ˈaŋmar]) (on certain maps: Ângmâr) is a fictional kingdom in J. R. R. Tolkien's continent of Middle-earth.
Angmar was founded in T.A. 1300 in the far north of the Misty Mountains by the Lord of the Ringwraiths, who became known as the "Witch-king of Angmar". The Witch-king came north to attack the Dúnedain of Arnor, whose disunity made them an easier target than Gondor at that time.
The capital of Angmar was Carn Dûm where a race of evil men lived. Carn Dûm was established at an unknown date near Mount Gundabad.
Soon after Angmar was founded it waged war against the divided Dúnedain realms of Arthedain, Cardolan and Rhudaur. The Witch-king conquered Rhudaur, the weakest of Arnor's successor kingdoms, and replaced its Dúnedain king with one of the native Hillmen, a wild tribe of men possibly descended from the "accursed" kin of Ulfang.
Now under the Witch-king's control, Rhudaur in T.A. 1356 invaded Arthedain and in the attack, Arthedain King Argeleb I was slain. However, with the aid of the armies of Cardolan, Arthedain managed to maintain a line of defence along the Weather Hills.
Hearken to this loud noise from the Earth's heart
A doom laden change can start
When the world overturns
Mankind will return to dust
When the waters of the abyss submerge the mountains,
The clouds will be torn by the crests of waves
As the sea will cover up the land
The face of the world will change
The human race shall be entombed in the flood
Only the minds shall outlive the sinking of the bodies
And shall wait up like fog in the air
This giving birth to the consciousness of a brand new world
The memory of the human creatures
Shall endure only through the reek
Of their decaying corpses
As the sea will cover up the land
