The Merovingian Period refers to a time in early medieval history, specifically from the 5th to the 8th century, when the Merovingian dynasty ruled over the Franks in what is now modern-day France and parts of Germany. This era is marked by the establishment of a unified Frankish kingdom, which played a crucial role in the transition from Roman rule to medieval Europe. The Merovingians are known for their distinctive long-haired kings, such as Clovis I, who united various Frankish tribes. The period also saw the rise of Christianity, with the church gaining influence and power, setting the stage for future developments in European history.
