In "The Lord of the Rings", who was the sidekick of the protagonist Frodo Baggins?

Samwise "Sam" Gamgee is a fictional character in J. R. R. Tolkien's Middle-earth. A hobbit, Samwise is the chief supporting character of The Lord of the Rings, serving as the sidekick of the protagonist Frodo Baggins. Sam is a member of the Fellowship of the Ring, the group of nine charged with destroying the One Ring to prevent the Dark Lord Sauron from taking over the world.

Sam was Frodo's gardener. He was drawn into Frodo's adventure while eavesdropping on a private conversation Frodo was having with the wizard Gandalf. Sam was Frodo's steadfast companion and servant, portrayed as both physically strong for his size and emotionally strong, often pushing Frodo through difficult parts of the journey and at times carrying Frodo when he was too weak to go on. Sam served as Ring-bearer for a short time when Frodo was captured; his emotional strength was again demonstrated when he willingly gave the Ring back to Frodo. Following the War of the Ring, Sam returned to the Shire and his role as gardener, helping to replant the trees which had been destroyed while he was away. He was elected Mayor of the Shire for seven consecutive terms.
