1, Washington Washington needless to say, the father of America. The first president in American history and the first commander-in-chief of the US Army. But Washington has a black history, that is, he is the owner of the manor. And a supporter of slavery. But before he died, he made a will and released all his slaves. Although he once led the American army to fight for Britain, he eventually went to war with Britain because of his interests. Finally, the British colonists were driven away and the United States was established. As the father of America, Washington has a very high status. And he set a precedent, that is, the president's power is peaceful and excessive. This is the first time in the history of many countries, because many countries were feudal at that time, and the price of feudal system was that it was difficult to be peaceful and the foreign surname was too powerful.
2. If Washington is the father of America, then Jefferson is the person who helped Washington become the father of America. As the third president of the United States. He has three major achievements. The first is to give the United States more territory, and the second is to abolish the slave trade. The third is to make the American economy advance by leaps and bounds, especially the agricultural economy. Not only that, Jefferson also founded the University of Virginia, which is one of the top universities in America today. In addition, after he retired from the presidency, he began to reform the education system. Jefferson was very concerned about American agriculture and education all his life and made many far-reaching things.
3. Lincoln Regarding the achievements of President Lincoln, I believe that the first thing that many people think of is to stop the division of the United States. Lincoln's action on racial discrimination is actually divided into two levels. Some people think that the fundamental reason why Lincoln abolished slavery was to enable him to win the South. However, some people think that Lincoln's abolitionist system was successful, but it failed because of assassination. Actually, I personally prefer the second view. Lincoln had the idea of abolishing slavery, but because of his assassination, Lincoln had no time to realize his ideas and views.
4. Roosevelt About Roosevelt, I think he has two great achievements. The first is aimed at unemployment. In addition, unemployment is the enemy that Roosevelt struggled with all his life. The second great achievement is to lead the United States to win World War II and successfully invite the isolationist system. Although Roosevelt was in a wheelchair all his life, he led the United States to the top of the world.
