The Fellowship of the Ring in J.R.R. Tolkien’s novel had nine members.
The group was formed in Rivendell to help carry the One Ring toward Mordor and destroy it in the fires of Mount Doom. Its members were Frodo Baggins, Samwise Gamgee, Merry Brandybuck, Pippin Took, Aragorn, Boromir, Gimli, Legolas, and Gandalf.
The number nine deliberately corresponds to the nine Nazgûl, the Ringwraiths serving Sauron. The Fellowship combines representatives of several peoples and regions, including Hobbits, Men, a Dwarf, an Elf, and a wizard. This alliance reflects the need for cooperation against Sauron’s power.
The Fellowship does not remain together for the entire journey. It breaks apart after the events at Amon Hen, when Boromir dies and Frodo and Sam continue toward Mordor. The other members follow separate paths before reuniting later in the story.
