10 Greatest Fantasy Books of the 20th Century, Ranked by Their Lasting Worlds

A Brutal Political World
A Song of Ice and Fire breaks with familiar fantasy conventions by placing politics, scheming and consequential danger at the center of its story. In A Game of Thrones, beloved characters are never guaranteed safety, while the world’s history and rivalries feel older than the events readers witness.
The first book brings together action, feuding nobles, old grudges and a large cast against the shadow of a supernatural threat. Its success on bestseller lists helped turn the series into a global pop culture phenomenon.
A School for Wizards
Harry Potter and the Philosopher’s Stone introduces a playful wizarding world after Harry leaves the Dursleys’ home. Goblin-run banks, enchanted sweets, flying broomsticks and Hogwarts give the story a welcoming sense of discovery.
Harry’s friendship with Ron and Hermione anchors the adventure, while the mystery of the Philosopher’s Stone gives their first school year momentum. The book’s appeal helped make the series a major pop culture force, especially among young fans.
Rabbits on the Move
In Watership Down, a vision of coming destruction leads Fiver to urge his brother Hazel and a group of rabbits to leave the Sandleford warren. They escape shortly before humans destroy their home, beginning a tale that combines adventure, survival and political conflict.
Richard Adams portrays the rabbits as animals, grounding their behavior in biology and giving them their own language, customs and mythology. The story can be poignant, frightening and brutal, with the rabbits’ legends including the trickster hero El-ahrairah.
Middle-earth’s Ancient History
Published after its author’s death, The Silmarillion traces Middle-earth’s mythology from the creation of the universe through the wars and upheavals of the First Age. Its central conflict begins when Fëanor makes the Silmarils, jewels holding the light of the Two Trees, and Morgoth steals them.
Fëanor and his sons swear an oath that drives generations of bloodshed. The book also contains stories of Beren and Lúthien, Túrin Turambar, Gondolin, Eärendil and the destruction of Beleriand, adding depth to an already intricate world.
