In the Second Age, the Men of the White Mountains broke their oath to Isildur. This crime combined by Isildur's curse turned the Oathbreakers into shades who haunted the mountains until the Third Age. Aragorn II, in the capacity of the Heir of Isildur, released the Oathbreakers from their curse in return for their aid at Pelargir.
The most famous of the wraiths were the Ringwraiths, Men ensnared by Sauron's Nine Rings. Some of the victims of the Ringwraiths, too, could be transformed into wraiths, albeit lesser and under their command (although there are no records of such a being). This nearly happened to Frodo Baggins, after having been stabbed by the Morgul-knife of the Witch-king.
