The allagion (Greek: ἀλλάγιον) was a Byzantine military term designating a military unit of 50-400 soldiers. It first appeared in the mid-to-late 10th century, and by the 13th century had become the most frequent term used for the Byzantine army's standing regiments, persisting until the late 14th century.
