Morgoth

Summary
Morgoth, once named Melkor, is the primary antagonist of The Silmarillion, and the master and predecessor of Sauron, in-turn eponymous primary antagonist of The Lord of the Rings History.

Once part of the Valar (Archangels), Melkor became the first Dark Lord who was named Morgoth Bauglir in Beleriand and Middle-earth. He became greedy and hungry for Light, but seeing it was inaccessible to him, he turned to Dark, coveting it and, by seducing many Archangels and angels and corrupting them for his course, he filled Dark with a fear for all future life. Melkor marred the Great Music of the Valar with his selfish ambitions and inspired fear and corruption amongst his brothers and sisters. Eventually, Iluvatar, God, rebuked Melkor for his pride, and reminded him that pride was his weakness. Ashamed, Melkor withdrew, but when Iluvatar showed the Valar His new creation: Earth, Melkor longed to possess it. He gained a foothold on Earth's newly created surface and fell into battle with his brethren, which lasted all through Earth's early history. Eventually, Melkor claimed Kingship over Earth and declared himself god of the realm, but it took the combined efforts of Elves, humans, Valar, and all the Free Peoples of the world to defeat him. The Valar captured him and thrust him through the Door of Night bound in a great chain, Angainor.

Amongst the Maiar (angels) that Melkor corrupted was Sauron, who was the greatest Maiar that has been created. Sauron became most like Melkor in corruption. Melkor handed some of his powers to Sauron to corrupt and govern Earth, but Sauron was not defeated until some 3500 years after Melkor's defeat. Melkor's lies and illusions live on in the souls of humans and Elves, who have inherited the world, & takes shape in men as the fear of death. Death began as a gift to humans from Illuvatar, allowing them to separate from the world & go to astral parts unknown (possibly Eru's original inhabitance, where the Valar dwelt before coming to Valinor as Ainur), which elves cannot do as they are bound to it eternally. He warped this gift to be perceived as a curse and an insult, as if immortality had been stolen from Men. Sauron later uses this to his advantage on the Numenorians.
