Abstract
With the development of capitalism in the USA in the 50s and 60s of the nineteenth century, social and economic changes took place in society. During this period, under the influence of the industrial revolution, the country's economy developed rapidly. In the northern regions of the United States, the number of factories has increased, and instead of agricultural production, the transition to an industrial economy has begun. This trend has led to the strengthening of capitalist relations. However, there were also negative consequences of the development of capitalism. The institution of slavery has been preserved in the southern states, and this system has undergone significant changes in the economic structure of the country. Slaves worked in agriculture and on plantations, which caused workers to be highly dependent and violated human rights. The issue of slavery caused a sharp debate in society, and this problem became one of the main factors leading to the civil war. The article examines the problem of slavery related to the development of capitalism in the United States, conflicts and contradictions between different strata of society. It is reported that the economic and social differences between the northern and southern states have deepened and had a great impact on the future of the country.
