In the novel "Lord of the Rings", how many rings of power were given to the race of man?

The story behind the answer

9 is correct because, as the Ring-verse declares, “Nine for Mortal Men doomed to die.” In the Second Age, Sauron helped forge the Rings of Power: three for Elves, seven for Dwarves, nine for Men, and One Ring he made to rule them all. The nine rings corrupted their human bearers, who craved power and longevity, ultimately transforming them into the Nazgûl (Ringwraiths), Sauron’s most feared servants.

Memory tip: recall the pattern 3–7–9–1 from the verse—Elves (3), Dwarves (7), Men (9), and the Dark Lord’s One Ring. Also, think “Men are mortal and many,” so they received the most among the Free Peoples—nine—making them the easiest to ensnare.
