There is some disagreement as to when France came into existence. The earliest date would be the establishment of the Merovingian Frankish kingdom by Clovis I in 486 with the defeat of Syagrius, the last Roman official in Gaul. That kingdom's rulers were deposed in the 8th century. The Treaty of Verdun established the Kingdom of Western Francia in 843. Another date favored by many medieval historians is 987, the beginning of the Capetian Dynasty.
