1911 Encyclopædia Britannica/Marcomanni
MARCOMANNI (i.e. men of the mark, or border), the name of a Suevic tribe. With kindred peoples they were often in conflict with the Roman Empire, and gave their name to the Marcomannic War, a struggle waged by the emperor Marcus Aurelius against them and the Quadi. The Marcomanni disappeared from history during the 4th century, being probably merged in the Baiouarii, the later Bavarians.
