Since the independence and the formation of a federal state in the country obstacles to the rapid development of bourgeois relations were eliminated. At the end of the XVIII century the industrial revolution started here. However, it covered only the northern states. South remained agricultural and slave (in 1860 there were about 4 million slaves).
Within American society, in the congress a constant struggle of the capitalized system of the North and the slave-owning South was continuing. For some time, the conflict between supporters and opponents of slavery was settled by artificial differentiation: to the north of 36 degrees of north latitude and to the west of the Missouri River slavery was forbidden.
The Republican Party, which was aimed at the abolition of slavery, won in the elections of president in November 860.
The categorical opponent of slavery, Abraham Lincoln, was elected as a President. The balance of forces has shifted sharply in the direction of the industrial North. He understood that the abolition of captivity turned from rhetoric into a practical plane. The states on the south decided to act decisively. At the beginning of 1861, eleven slave states from the south declared their separation from the United States. They formed an alliance “The Confederation of American States”, elected its president D. Davis, adopted a constitution, and proclaimed their capital – the city of Richmond. The rebellion divided the country into two parts with their presidents, parliaments and the capitals.
In April 1861 the Southern states began military actions against the north. At the same time according to the Constitution Abraham Lincoln declared the states from the southern part of the country to be the rebels. The Civil War ended on May 26, 1865. It was the complete victory of the North. Confederate States ceased to exist. On the presidential elections in November 1864 Lincoln was re-elected, and on April, 14 during the celebration on the occasion of the victory in the Civil War, President Abraham Lincoln was fatally wounded.
The civil war has led to major changes in the economic, political and legal system of the United States. It destroyed slavery, abolished the remnants of pre-capitalist social structures, thanks to Homestead Act finally decided agrarian problem by transferring the previously nationalized lands of the Northwest in the property of farmers. Finally the so-called American way of development of capitalism in agriculture was approved, where the key figure became the capitalist farmer. In this respect the war between the North and the South may be considered as a continuation and completion of the bourgeois revolution, which began the war for independence.
