Final answer:
Napoleon restored legal order in France by reinstating the old nobility, introducing the Napoleonic Code, and implementing economic reforms.
Step-by-step explanation:
Napoleon restored legal order in France through several actions. Firstly, he reinstated members of the old nobility who had been discredited or imprisoned by the Revolution, allowing them to reclaim some of their property. He also introduced the Napoleonic Code in 1804, which established a uniform set of laws that granted basic rights and outlawed the privileges of the nobility. Additionally, Napoleon worked to improve the French economy through measures such as creating the Bank of France and implementing a tax system that was equitable to all citizens. These actions helped stabilize life in France and restore order after the French Revolution.
