Between 850-1100 CE, Europe experienced new invasions from Vikings, Magyars, and Saracens due to the decline of the Carolingian and Byzantine Empires. The Vikings originated from Scandinavia and first raided England and other parts of Europe for treasure before eventually conquering territories like England, founding kingdoms in Scandinavia, and establishing themselves in Normandy. They also engaged in trade along coastal regions. Meanwhile, the Magyars invaded from Asia and established the Kingdom of Hungary after raiding parts of Germany, Italy, and France. Additionally, Saracen pirates attacked Mediterranean coastal cities seeking treasure following the fall of the Carolingian Empire.
