Napoleon, unlike Louis XVIII controlled armed forces, police, legislation, and could declare war. His domestic policies were a success. He stimulated the construction of roads, railroads, and canals, and under Baron Haussmann reconstructed all of Paris to become an area of broad boulevards, plazas, etc. He also liberalized the regime, reaching out to the working class through granting unions and strikes, allowed candidates to campaign, and allowed the Legislative Corps more say in government. In terms of his foreign policy, however, he was not so successful in his Mexican adventure when he left his troops there and an emperor with no backup (executed) and the Crimean war, where he defeated Russia. However, in the Franco-Prussian, he underestimated the Prussian’s power and was defeated.
