Washington:

(1) in the military contribution, but not "genius commander in chief". The reasons are: the battle commanded by Washington does not constitute a fatal blow to the British army; Did not play a key role in the whole war; There are no military deeds that can be called "genius"; Military art is not original.

Politically, he is a bourgeois activist, but he is not an outstanding politician. The reasons are: Washington is a moderate in the continental congress; Never a sincere supporter of the Declaration of Independence; It didn't play much role in seeking international assistance; After the war of independence, the United States retreated from the revolutionary period; Taking Halton's side against democracy: not enthusiastically supporting the French Revolution.

Washington is moderate, incomplete and always belongs to the right wing.

Washington is very popular with plantation slave owners and the bourgeoisie. Because his policies and words and deeds during his presidency were based on the interests of plantation slave owners and the big bourgeoisie; He himself became one of the richest men in America.

Napoleon: He was an outstanding bourgeois politician and strategist in France. 1799 launched a foggy month coup and established an executive government. 1804 crowned emperor and established the first empire of France.

Napoleon carried out fiscal and tax reforms in China, founded the Bank of France and encouraged the development of capitalist industry and commerce. Promulgate a series of codes, such as the Civil Code, to establish the legislative norms of capitalist society; Establish public middle schools and French universities, encourage scientific research and technical education, and train talents for France. These measures are conducive to France's political stability and the development of capitalism, further destroying France's feudal system and consolidating the order of capitalist society.

He fought many wars with the anti-French alliance abroad. He defended the achievements of the French Revolution and spread the ideas of the French Revolution through the early foreign wars, which was objectively beneficial to the disintegration of the feudal system in Europe and the liberation of farmers. However, in his later wars, he violated the independence of many countries, plundered and enslaved the people of European countries, aroused the resistance of people everywhere, and finally led to the collapse of Napoleon's empire.

In a word, Napoleon had merits and demerits, and his merits and demerits were greater than his own.

In order to make a reasonable evaluation of historical figures, we must adhere to the principle of historical materialism and pay specific attention to the following points:

1. Specific historical background. The background is a big stage for the activities of historical figures. If the same activity of characters is in different historical backgrounds, different evaluations can be made.

2. Determine the evaluation criteria. We can't treat a person's activities or behaviors emotionally, nor can we just consider them from a moral point of view. It depends on whether it is conducive to the development of productive forces, social progress and national unity.

3. Prevent generalizations. Generally speaking, no one is perfect, that is to say, the evaluation of characters should be divided into two parts, comprehensive and objective. We should consider the class and era of historical figures.

4. Overcome the heroic historical view. Successful people in history are made by the times, and at the same time, we should admit that the personality characteristics of characters have a certain influence on things.

5. According to the effective information provided by specific materials, we should overcome the mindset and make a comprehensive analysis of the material viewpoints and related knowledge of teaching materials.

6. The evaluation of historical figures must be based on historical facts and must not be subjective and groundless. That is, to evaluate historical figures on the basis of possessing a large number of historical materials.
