Who was Napoleon Bonaparte? Why was he called a liberator?
Answer:
In 1804, Napoleon Bonaparte crowned himself the Emperor of France and reintroduced monarchy in France. He conquered his neighbouring countries and created kingdoms, where he placed his own family members. He was called a moderniser of Europe. He introduced many laws such as the protection of private property and a uniform system of weights and measures provided by the decimal system. Initially, many people believed that Napoleon was a liberator who would bring freedom for the people. But soon his army was viewed as an invading force. So, he was finally defeated in 1815, in the famous ‘Battle of Waterloo’. Many of his measures that carried the revolutionary ideas of liberty and modern laws to other parts of Europe had an impact on people long after Napoleon had left.
