It was the greatest battle of the War of Dwarves and Orcs, and was a decisive victory for the dwarves. However, the battle had claimed the lives of many; including Frerin the second son of Thráin II, and the younger brother of Thorin Oakenshield. His kinsman Fundin also fell. Náin son of Grór was slain in a fight with Azog the Goblin right outside the East Gate. Azog was then slain in turn by Náin's son Dáin Ironfoot.
After the Orcs were routed, Thráin II, heir of Durin, wished to enter and reclaim Moria after the War. However, the Dwarves of Durin's folk were too few, and the Dwarves of the other six houses refused to get involved with Durin's Bane.
The aftermath of the battle and the overall war resulted in heavy losses for all the dwarves involved, but virtually all of the Orcs infesting the Misty Mountains were destroyed, leaving only a handful left. This resulted in the Misty Mountains being relatively safer for the next two centuries. The Battle of Azanulbizar was also where Thorin earned the name "Oakenshield"; after his shield was broken during the battle, he cleaved a great branch from a nearby oak tree to use as both defense and bludgeon.
The name 'Azanulbizar' is a Khuzdul word.
