Can you help me find some history of being forced to move because of the war?

During the reign of Kangxi in the Qing Dynasty, the Turki tribe in Yili, Xinjiang, went through many hardships and moved back to Xinjiang from Russia.

During the Roman Empire, ostrogoths, Visigoths, Germans, Franks and Anglo-Saxons migrated westward to avoid Huns from the East, and moved from today's Poland, Hungary, Romania and Bulgaria to today's Western Europe.

Ostrogoths and Visigoths migrated to the Balkans after invading and plundering the Roman Empire.

The Germans moved to present-day Germany, and the Franks invaded Rome, which is now France, and established the Frankish Kingdom on the ruins of Rome.

Anglo-Saxons have been migrating to overseas islands, and what later generations called "Great Britain" is their final destination.
