Well Sauron made them as slaves for the One 😉
He started to teach the elves making rings and stuff around 1200 Second Age; in the following centuries he made the Seven Rings of the Dwarves and the Nine Rings of the Nazgul (and the Witchking's ring is the mightiest of them) while the Elves alone made the Three Rings of the Elves.
Sauron finished the One around 1600 S.A.... it isnt known exactly when he made the Nine Rings.
In the following years Sauron gave the Rings to nine Kings/Lords of Men (mostly in Rhûn and Harad/Umbar) who desired the power they had
(vs. prologue...) they soon fell victims to Sauron and became his most important slaves, the Nazgul - bound by the One Ring.

oh no no... you can have your own opinions... i don't mind... i just hate it when people here say that my opinion on arwen is stupid, and critize it... but you know how people may be... Frodo and Legolas are both very fine men.... 😄 😍 but i'm more of a Aragorn/Viggo fan... especially since you get to see his naked a** in some movies and even the front part... 😍 though i haven't seen the movie yet... 🙁 someday though...
