Nineteen Rings of Power are given to the races of Middle-earth in J.R.R. Tolkien’s Ring poem.
The poem in The Lord of the Rings counts three Rings for the Elves, seven for the Dwarves, and nine for mortal Men. Adding those groups gives 19. The verse then separately identifies the One Ring, made by Sauron to dominate the others, producing the familiar total of 20 Rings of Power.
The distinction matters because people often answer 20 when asked how many rings were distributed to the three races. Twenty is the total number named in the poem when the One Ring is included; nineteen is the number given to Elves, Dwarves, and Men.
The three Elven Rings were Narya, Nenya, and Vilya. The Dwarves received seven, although Sauron did not successfully control them in the same way. The nine rings given to Men eventually transformed their bearers into the Nazgûl.
