All the gods created the world with music but melkor (one of the great gods) was an asshole and decided to be evil. he took a lesser god (sauron) and lot's of spirits and such (balrogs) and created evil stuff (orcs, dragons) after many many battles with the eles and gods, the great gods decided to tear his fortress apart and kill him.
Enter, Sauron. a few other lesser gods came to middle-earth (Gandalf, Radagast, Saruman and the two blue wizards of the east) and the rest is common knowledge.
Morgoth is still alive. He's trapped in the 'Void', and supposedly will come back, along with all his servants, for the Dagor Dagorath, or Battle of Battles.
Also, they destroyed more than his fortress. The entire continent it was on sank into the sea.
Final thing, the Blue Wizards were named Alatar and Pallando.
Sorry if I sound like a smartass, just thought I'd point it out.
OT: As has been mentioned a lot already, he was a minion, but as of The Lord of The Rings, he served himself.
