The Eldar: The war of the jewels

The crimes of Melkor in Aman and the subsequent rebellion of the Ñoldor started a centuries-long war that would come to involve all the Elven kindreds of Middle-earth, as well as other races, directly or indirectly. During this time, five great battles were fought against Morgoth and although many were victorious for the elves and their allies, the ultimate result was disastrous. Additionally, the doom that followed the Ñoldor as a result of the Kinslaying at Alqualondë was discovered by Thingol, the King of Doriath and High King of the Sindar. This discovery all but destroyed the relationship between the Sindar and the Ñoldor. There were also other elves and races such as the Petty-dwarves that resented the exiled Ñoldor for usurping their rightful place in Middle-earth.
