Fechtbücher are historical manuals that detail the art of fencing and combat techniques, primarily from the late Middle Ages to the Renaissance. These books served as instructional guides for knights and soldiers, illustrating various fighting styles, weapon usage, and strategies. They often included diagrams and illustrations to help readers understand the techniques being described. The most famous Fechtbücher were created by masters like Johannes Liechtenauer and Sigmund Ringeck, who documented their knowledge for future generations. These texts not only focused on swordsmanship but also covered other weapons, such as daggers and polearms, reflecting the diverse martial practices of the time.
