Final answer:
The French allowed Napoleon to proclaim himself emperor due to his military victories, portrayal as a symbol of power, and strategic alliances with the old nobility.
Step-by-step explanation:
The French allowed Napoleon to proclaim himself emperor for several reasons. First, Napoleon established his power through military victories and brought stability to France after the chaos of the French Revolution. He was seen as a strong leader who could maintain order.
Second, Napoleon portrayed himself as the heir of great historical figures like Alexander the Great and Julius Caesar. By proclaiming himself emperor, he presented himself as a symbol of power and glory, appealing to the people's desire for a strong and prestigious leader.
Finally, Napoleon strategically reinstated members of the old nobility and allowed them to reclaim some of their property that had been taken during the Revolution. This helped him gain support and loyalty from the aristocracy.
