Answer:
need to centralize political power
Step-by-step explanation:
The political turmoil and constant warfare led to the rise of European feudalism, which, as you read in Chapter 2, is a political and economic system based on land ownership and personal loyalty. From about 800 to 1000, invasions destroyed the Carolingian Empire.
The invasions by Vikings, Magyars, and Muslims caused widespread disorder and suffering. Most western Europeans lived in constant danger. Kings could not effectively defend their lands from invasion. As a result, people no longer looked to a central ruler for security. Instead, many turned to local rulers who had their own armies. Any leader who could fight the invaders gained followers and political strength.
