His Dark Materials is a famous trilogy of fantasy novels. 
In this story, the characters encounter many magical things. Lyra meets flying witches and armored polar bears. She also uses a special tool called an alethiometer. This is a device that tells the truth. The books also talk about big ideas from science and religion. The series uses ideas from a poem by John Milton. That poem is called Paradise Lost. Pullman even took the name of his series from that poem. 
Pullman wrote the books with many different ideas in mind. The story moves between many different worlds. In the first book, the world looks a bit like the UK in the Edwardian era. There are no cars or airplanes there. Instead, people use large zeppelins to travel. The religious leaders in Lyra's world are called the Magisterium. This group has a lot of power over how people live. In this world, the center of religious power is in Geneva, Switzerland. This is different from the real world where the center is in Rome.
Many people have brought these stories to life on screen. 
Philip Pullman has continued to write in this same universe. He wrote four short works after the main trilogy. These include Lyra's Oxford and Once Upon a Time in the North. He also started a new trilogy called The Book of Dust. The first book in that set is La Belle Sauvage. The second book is The Secret Commonwealth. The final book, The Rose Field, was published in October 2025. These stories keep the magic of the original books alive for readers.
His Dark Materials is a celebrated trilogy of fantasy novels written by Philip Pullman. 
The mechanism of the story relies on the interaction between characters and their unique environments. In Lyra's world, humans possess dæmons, which are physical manifestations of their souls. A central conflict involves the Magisterium, a powerful religious authority that exerts absolute control over society. The Magisterium attempts a procedure called intercision, which is the forced severing of the bond between a human and their dæmon. This process is intended to prevent the onset of adult emotions. Additionally, the plot utilizes the alethiometer, a truth-telling device that Lyra uses to navigate her journey.
The trilogy features several distinct worlds and magical entities. The first novel takes place in a world resembling the Edwardian era of the United Kingdom. In this setting, technology includes zeppelins instead of cars or fixed-wing aircraft. The second book introduces the city of Cittàgazze, where residents use technology to move between worlds. This reckless use of travel creates Spectres, which are entities that destroy adult souls but cannot harm children. The third book introduces the Land of the Dead and a world populated by sentient creatures called Mulefa. These different stages of travel create a complex web of cause and effect across the multiverse.
Pullman drew significant inspiration from the 17th-century epic poem Paradise Lost by John Milton. 
The commercial and critical success of the trilogy is substantial. By 2024, more than 22 million copies of the novels had been sold across 50 different countries. The text has been translated into 40 different languages to reach a global audience. The series has won several prestigious awards, including the Carnegie Medal in 1995 and the Whitbread Book of the Year in 2001. In a 2003 poll by the BBC, the trilogy was ranked third in The Big Read. These figures demonstrate the massive cultural impact of Pullman's storytelling.
Many adaptations have brought these stories to various media formats. 
Pullman has expanded this universe through several subsequent works. He wrote four short stories set in the Northern Lights universe, including Lyra's Oxford and Serpentine. He also began a new trilogy titled The Book of Dust, starting with La Belle Sauvage in 2017. The second book, The Secret Commonwealth, followed in 2019. The final volume, The Rose Field, was published on October 23, 2025. These works continue to explore the intricate connections between the characters and the vast, interconnected worlds they inhabit.
