The trilogy, dubbed the Crusades trilogy, consists of the following books:
- The Road to Jerusalem, originally Vägen till Jerusalem (1998)
- The Knight Templar, originally Tempelriddaren (1999)
- Birth of the Kngdom, originally Riket vid vägens slut (2000)
Guillou also wrote a follow-up novel about Birger Jarl, founder of Stockholm, entitled The Heritage of Arn (in Swedish Arven efter Arn) published in 2001. In Guillou's fictional universe, Birger Jarl is the grandson of Arn Magnusson.
The books were reworked to a film released in December 2007: Arn – The Knight Templar (In Swedish: Arn - Tempelriddaren, and its sequel Arn – The Kingdom at Road's End (in Swedish: Arn – Riket vid vägens slut), released August 22, 2008.
While the films are mostly in Swedish and most of the production was made in Sweden, the film is a joint production between the four Scandinavian countries of Sweden, Denmark, Norway and Finland and Germany. With a total budget of around 210 million Sweidsh Krona (ca. 30 Million US$ for both films, it is the most expensive production in Swedish cinema.
Based on the detailed stories by Guillou, the question may be put forward: did the Knights Templar really live in Sweden? This question will be dealt with in another blog.
It's worth mentioning that there is a decent mini film series based on these books: link.
