186 1- 1865 What bloody events have happened in North America? It is said that more than 600,000 people died.

The Civil War, also known as the American Civil War, was a large-scale civil war in American history. The two sides involved in the war are the United States of America (referred to as the Federation) and the United States of America (referred to as the Confederacy). The war broke out because 1 1 states in the south of the United States withdrew from the union on the grounds that abraham lincoln became president in 186 1, set up a government with Jefferson Davis as the "president", expelled the federal troops stationed in the south, and Lincoln ordered to attack the "rebellious" states. This war not only changed the political and economic situation in the United States at that time, but also led to the final abolition of slavery in the southern United States, which also had a great impact on the later American civil society. Because of the contradiction between the plantation economy in the south and the capitalist economy in the north, most slaves were escorted to the south of the United States and demanded independence. The south started the war first (by shelling Fort Sumter). The federal army recruited blacks as never before. Although most black soldiers were only assigned to some low-level jobs, President Lincoln still won the support of black slaves (but this was not the main factor for the victory of the Civil War). States in the United States have been arguing with the central government, whether it is the power of the central government or the loyalty of citizens, and this competition has been unveiled almost from the beginning of the establishment of * * *. For example, Kentucky and Virginia's resolution 1798 openly opposes Hakka law and foreigners and incitement. In addition, in the Hartford Convention, New England expressed its opposition to President Madison's war with 18 12. In fact, the relationship between the Civil War and the abolition of slavery is not obvious in the eyes of white Americans. 1828 and 1832, the national assembly passed the tariff increase on European industrial products to benefit the industries of the northern States. Because this tariff policy will have an economic impact on South Carolina and other southern states, which are heavily dependent on exporting agricultural products to Europe, American southern agriculture is ridiculed as "tariff aversion" because it is worried that European countries will retaliate against the United States and raise tariffs on American agricultural products. In response, the South Carolina legislature convened a state congress, and by repealing the laws, it declared that the 1828 and 1832 tariff laws were invalid in the state. The state legislature has also passed relevant laws to implement regulations, including authorizing the organization of troops and the purchase of weapons. In response to the threat from South Carolina, Congress passed the force bill. In June 1 832+065438+1October, President Jackson sent seven small naval vessels and1armed warships to Charleston. In February, 10, 10, Jackson refuted one side of the provisions on the right to annul federal statutes. On the eve of the Civil War, the United States was a country composed of four distinct regions: the northeast (that is, today's New England)-the industry and commerce developed day by day, and the corresponding population density increased; Northwest China (today's Midwest)-Free peasants developed rapidly here, and there was no slavery here forever because of the Northwest Law. Upper south-reclamation farm, but some areas are in economic recession; Southwest China-a cotton economic zone that has mushroomed. At this time, a masterpiece that shocked the world, Uncle Tom's Cabin, was published. It was forcibly reprinted as soon as it was published. The reader wipes his tears while reading, and the observer has a sore nose while listening. The publication of this book made the people in the north know the bitterness and tears of slaves and accelerated the promulgation of the "Abolition Order". Before the outbreak of the civil war, the American Constitution provided the basis for peaceful debate for the future government, and it could balance the conflicts and contradictions of interests in this new state relationship. A few years later, the number of free States and slave States gradually balanced the Senate through compromise. Texas, the last slave state, was recognized in 1845, and five free states were recognized between 1846 and 1859. Kansas, originally a slave-holding state, was rejected before and joined as a free state in 186 1. Subsequently, a large-scale democratic industrial revolution and industrialization wave arose in the north, and the old two-party system was lifted. The increasingly hostile ideology makes it increasingly impossible to conclude gentleman's agreements (such as Missouri compromise and 1850 compromise) to avoid crises in the past. At the same time, the use of slaves in the southern States makes the northern States the first choice destination for new immigrants, so that the advantages of the north in parliamentary and presidential elections are getting stronger and stronger according to the population size. 1850 s, the party struggle took a sharp turn in essence and intensity. The American Republican Party was founded in 1854. Both this new political party and Lincoln are opposed to free trade and easy trade in order to protect the emerging industries in the northern United States, which is completely opposite to the position of the Republican Party today (Harvard Business Review, April 2009). In order to win the support of the majority of voters who opposed slavery in the north, the * * * and the party were initially vague about slavery. * * * The Republican Party has won many former Whigs and former members of the Democratic Party in the North. They are worried that the US Senate, the Buchanan administration and the Supreme Court will be disproportionately influenced by the South. At the same time, the rich profits of cotton deepened the south's dependence on farming and slaves. The owners of a few slaves, especially cotton growers, controlled the politics and society in the South. * * * Republican Lincoln's election triggered a split in the South. Lincoln was a moderate who opposed slavery. He promised to do his best to oppose the expansion of slavery in the new territory (that is, to prevent any new slave-holding States from joining the union); But he also said that the federal government could not abolish slavery in the state where it was implemented, so he would enforce the slave escape law. Worried about the abolition of slavery in some party member and the weakening of the power in the south, South Carolina finally declared its secession, which eventually led to the secession of other southern states. Lincoln even encouraged abolitionists in 1858 to gradually and peacefully terminate slavery by giving economic compensation to slave owners and organizing former slaves to move out of slave-holding states. Because Lincoln won the presidential election, the slave state lost the balance of power in the Senate and will face continuous weakness after decades of control by the presidential palace and Congress. Renye Fang felt powerless to stop protectionist tariffs similar to Morelle's tariff law. Before the invalid crisis of 1798 and 1832 in Kentucky and Virginia, people debated it. Faced with the threat of tariffs, the South unilaterally exercised state power to secede from the Federation.
