Final answer:
The French newspaper headlines from 1815 show a shift in public opinion from anger to pleasure with regards to Napoleon's return. Initially labeled a 'demon', Napoleon regains popularity and is met with 'universal joy' as he promises reform and glory to discontented French citizens and soldiers.
Step-by-step explanation:
The chart showcasing the 1815 French newspaper headlines during Napoleon's 100 days reflects the transition in the French people's attitudes toward Napoleon from a negative to a positive light. Initially, Napoleon was depicted as a 'demon' and 'tyrant', attributing to him fear and terror. However, as he made his way to Paris and promised reforms, especially to French soldiers and citizens disillusioned with the monarchy, the perception shifted dramatically.
Napoleon's charisma and the promise of returning France to former glory turned public opinion in his favor, as seen by the final headline celebrating his arrival and signifying 'universal joy'. This change in sentiment is captured in the transition from 'fear and terror' to expressions of joy and welcoming of Napoleon's leadership. This illustrates a shift from anger to pleasure among the populace concerning Napoleon's return to power.
