Final answer:
The Frankish armies, led by Clovis and later Charlemagne, were powerful military forces that unified and expanded the Frankish territories, conquered most of Gaul, and stopped the Arab conquest in Europe. They were also instrumental in religious and political shifts in the region.
Step-by-step explanation:
According to Anna Comnena and historical accounts, the Frankish armies were a formidable military force that emerged from the Germanic tribe known as the Franks. Under the leadership of Clovis, these armies united various Frankish tribes and successfully expanded their territory into northern Gaul late in the fifth century, conquering most of Gaul and deposing the last Roman governor. In later centuries, the Frankish empire would become three territories, and their military might was demonstrated when they halted the Arab conquests in Europe at the Battle of Poitiers.
The Frankish armies were not only military conquerors but also played a significant role in shaping the religious landscape of the region. For example, Clovis' conversion to Latin Christianity was a strategic move that enabled him to win over the Gothic subjects in their campaign against the Visigoths. The Franks' influence continued into the eighth century, wherein Charlemagne, another notable Frankish leader, defeated the Lombards in Italy and further expanded the Frankish Kingdom.
