Answer
In 14 AD, Germanicus, husband of Agrippina the Elder, was appointed governor of Gaul. Gaul, also known as Gallia, was a vast province in Western Europe that roughly corresponded to modern-day France, Belgium, part of the Netherlands, western Germany, and northern Italy. As governor, Germanicus played a crucial role in maintaining peace, suppressing revolts, and securing Rome's control over the region.
