During the period of the great migrations (barbarian invasions) they affected extensive regions of the temperate zone of Eurasia, leading to the fall or destabilization of large consolidated empires such as the Roman Empire, occupying it violently or reaching political agreements.
They took place throughout a long historical cycle, between the 4th and 16th centuries, comprising practically all of Europe and the Mediterranean basin, marking the transition between the Ancient Ages and the Middle Ages that is known as Late Antiquity.
Several phases are distinguished in these migrations, the first ones corresponding to the Germanic peoples (from the 4th century to the 6th century), while the last ones correspond to the Vikings.
It is well known and well demonstrated that between the years 535 AD. C. and 536 AD. C. there was a period of extreme cold documented both archaeologically and by the chronicles of the time. Arctic ice records suggest that during the time of the great migrations there were relatively cold temperatures, which would have pushed people from the coldest regions of Eurasia to migrate south, in turn pushing other peoples who ended up putting pressure on the borders of the empires of the temperate zone such as the Roman Empire, the Sassanid Empire or the Gupta Empire.
During the decline of the Roman Empire, there were many barbarian peoples who, taking advantage of internal dissidence, approached its borders and settled there, constantly pressing to enter. The barbarians managed to penetrate slowly between the 1st and 4th centuries and establish themselves in the interior, until, finally, pushed by other peoples, they did so violently.
