Frodo begins his journey in the fictional land called the Shire in Tolkien’s The Lord of the Rings.
The Shire is a peaceful region of northwestern Middle-earth inhabited mainly by Hobbits. It contains villages and communities such as Hobbiton, Bywater, and Buckland. Frodo lives at Bag End in Hobbiton, the home inherited from Bilbo Baggins.
The quest begins when Frodo leaves the Shire with the One Ring. He is initially accompanied by Samwise Gamgee, Merry Brandybuck, and Pippin Took. Their departure marks the transition from the familiar rural world of the Hobbits to the wider dangers of Middle-earth.
Bree is a settlement outside the Shire, and Rivendell is an Elven refuge farther east. Eriador is the larger region containing the Shire, so it is less precise than the requested place. The Shire is the specific homeland from which Frodo sets out.
