George R. R. Martin's A Song of Ice and Fire has sparked a renewed interest in all things medieval. The pseudo-historical world of Westeros delights casual fans while offering a rich new perspective for medievalists and scholars of medievalism. This work is the first comprehensive study of Martin's Westeros as a reflection of the medieval concept of chivalry. It explores how Martin crafts a Westerosi chivalric code that intersects with and can illuminate well-known medieval texts, including both romance and heroic epic. Through characters such as Brienne of Tarth, Sandor Clegane, and Jaime Lannister, Martin variously challenges, upholds, and deconstructs chivalry as depicted in the literature of the Middle Ages. This book is primarily directed to scholars of medievalism, students of medieval literature, and teachers who are interested in including works of medievalism in their classes or developing courses solely devoted to medievalism. Casual readers of the novels and fans of the HBO series will also gain new insight into Martin's Westeros.
