Gunki Monogatari

Gunki monogatari (軍記物語?), or "war tales," is a category of Japanese literature written primarily in the Kamakura and Muromachi periods that focus on wars and conflicts, especially the civil wars that took place between 1156 and 1568. Examples of this genre include the Hōgen Monogatari and the Heiji Monogatari. The most well known gunki monogatari is Heike Monogatari.
