His successes on the battlefield, especially during the Battle of Breitenfeld (1631), showcased the effectiveness of his innovative strategies.

After his death in 1632, many of his reforms continued to shape military tactics and organization across Europe. His legacy is also reflected in the development of modern infantry tactics and the concept of a professional standing army.
