The German school of fencing is a system of combat taught in the Holy Roman Empire during the Late Medieval, German Renaissance, and early modern periods. It is described in the contemporary Fechtbücher written at the time. The geographical center of this tradition was in what is now Southern Germany including Augsburg, Frankfurt, and Nuremberg. During the period in which it was taught, it was known as the Kunst des Fechtens, or the "Art of Fighting". The German school of fencing focuses primarily on the use of the two-handed longsword; it also describes the use of many other weapons, including polearms, medieval daggers, messers, and the staff, as well as describing mounted combat and unarmed grappling (ringen).

Martial arts manuals are instructions, with or without illustrations, specifically designed to be learnt from a book. Many books detailing specific techniques of martial arts are often erroneously called manuals but were written as treatises.
