The correct answer is Increased regional and international economic dependencies.
During the 1830s and 1840s, the slogan "Cotton is King was widely used and described American's economy growth. Cotton became one of the first luxury commodities after sugar and tobacco and also expanded its production in such a way that millions of black human beings themselves became treated as a commodity, becoming the first mass consumer commodity in the world.
Slave-produced cotton brought commercial success and great profits to New York City, stimulated territorial expansion in the Old Southwest and strengthened bonds between Europe and the U.S. for trading, being the main export America had for over a century.
It is important to note that despite its economic importance, cotton also prolonged America’s most serious social tragedy, slavery, even having a major factor for the American Civil War. It had an enormous economic importance to the economies of the United States and Great Britain.
