What are Three statements that TRUE about Europe during the ninth and tenth centuries?

Three statements that are true about Europe during the ninth and tenth centuries are:

1.Fragmentation of the Carolingian Empire: After the death of Charlemagne in 814, the Carolingian Empire, which had united much of Western Europe, began to disintegrate. The empire was divided among Charlemagne's heirs and eventually fragmented into smaller kingdoms, duchies, and counties.

2.Viking Raids and Settlements: During this period, Europe faced increased raids by the Vikings, also known as the Norsemen. These seafaring warriors originated from Scandinavia and launched raids on coastal areas throughout Europe. They plundered monasteries, towns, and even major cities, causing significant disruption and fear. Some Vikings also established settlements and trading posts in various parts of Europe, including parts of the British Isles, France, and Russia.

3.Rise of Feudalism and Manorialism: The political fragmentation and the constant threat of invasions during the ninth and tenth centuries led to the emergence of feudalism. This social and political system was based on land ownership and military service. Powerful nobles and lords controlled vast estates, and peasants worked the land in exchange for protection and a portion of the harvest. Manorialism, which involved self-sufficient agricultural communities on these estates, became widespread during this period.
