One Ring [SEP] Purpose
The One Ring was forged by the Dark Lord Sauron during the Second Age to gain dominion over the free peoples of Middle-earth. In disguise as "Annatar", or "Lord of Gifts", he aided the Elven smiths of Eregion and their leader Celebrimbor in the making of the Rings of Power. He then forged the One Ring in the fires of Mount Doom. Sauron intended it to be the most powerful of all Rings, able to rule and control those who wore the others. Since the other Rings were powerful on their own, Sauron was obliged to place much of his own power into the One to achieve his purpose.
