JRR Tolkien considered Samwise Gamgee the "chief hero" of The Lord of the Rings. If you’re unfamiliar with The Lord of the Rings, it is a world famous story of the struggle of a group of people to destroy a powerful ring before it results in the resurrection of the evil Sauron. The “main character” of the story is Frodo Baggins, a hobbit (a person with large hairy feet and in short stature).
Frodo is tasked with taking the ring to Mordor, the place where it can be destroyed. Frodo is joined by his gardener, Samwise Gamgee. Throughout the course of the story, it might seem obvious that the main character and carrier of the ring is the story’s hero. J. R. R. Tolkien, the author, saw things differently though. Tolkien claimed that Sam was the true hero of the story.
To be fair, the claim holds some merit. Sam did beat a man eating giant spider in single combat, storm a tower full of orcs on his own, resist the temptation of the ring, and carry Frodo up the side of a volcano essentially carrying the fate of the world on his back- all while suffering from starvation and dehydration. So it seems to stand to reason.
