When did Berbers raid roman lands in north Africa?

Berbers, particularly the tribes in North Africa, began raiding Roman lands in the late 2nd century AD and continued into the 3rd century AD. These raids intensified during the Crisis of the Third Century (approximately 235-284 AD), as the Roman Empire faced internal strife and external threats. The raids were often motivated by the desire for resources and territory amidst the weakening of Roman control in the region.
