Final answer:
The strongest form of control after the fall of the Roman Empire during the Dark Ages was Feudalism. Lords granted land in return for military service and loyalty, which established a social structure based on land ownership and vassalage. Over time, changes in agriculture, trade, and the centralization of power led to the decline of feudalism. After the fall of the Roman Empire, the strongest form of control during the Dark Ages was Feudalism (A).
Step-by-step explanation:
After the fall of the Roman Empire, the strongest form of control during the Dark Ages was Feudalism (A). Feudalism developed as Europe became politically fragmented, with various Germanic tribes establishing early political units in the wake of Roman governance. This system was characterized by lords granting lands to vassals in exchange for military service and other obligations. Religious institutions also played a significant role in the governance of medieval Europe, but it was the feudal lords who exercised the most control over the regional lands and people.
The French monarchy, specifically, was weak during the early part of this era, and feudal landowners had significant regional power. It wasn't until the 12th century that the monarchy began to centralize power, and changes in agriculture and trade gradually led people back to the cities. Over time, due to factors like depopulation, shifts in military practices, and the centralization of monarchical power, feudalism began to decline.
