Describe the origin of cultivated American cotton.

Cotton has been a significant crop for thousands of years, with evidence dating back to 5000 BCE. While many species of cotton exist, four main species create the majority of the world's cultivated cotton. The origin of cultivated American cotton is linked to its native species, Gossypium hirsutum.

The first thing to know about cultivated American cotton is what species it is. The primary species of cultivated cotton in the Americas is Gossypium hirsutum, also known as upland cotton or Mexican cotton. This species is native to Mexico, Central America, and northern parts of South America.

The domestication process of Gossypium hirsutum began in the regions where it was native, such as the Yucatan Peninsula in present-day Mexico, Guatemala, and Honduras. Indigenous peoples in these regions used cotton fibers for various purposes, including clothing and textiles. Domestication occurred gradually over thousands of years, as people continued to grow and use this cotton and select for desirable traits.

Spanish explorers encountered American cotton, or Gossypium hirsutum in Mexico, Central America, and South America during the 16th century. These explorers brought the cotton back to Europe, and soon cotton seeds were disseminated through trade and colonization. When Spain colonized the southeastern United States, they introduced American cotton to the region.

Cotton cultivation expanded rapidly in the southern United States in the early 1700s. Due to the labor-intensive process involved with cultivating and processing cotton, the enslaved African population was used to grow and tend the cotton fields. The development of the cotton gin in 1793 by Eli Whitney greatly increased the efficiency of cotton production, contributing to the expansion of the cotton industry.

Starting from the early 19th century, American cotton became one of the most significant exports from the United States, heavily influencing the politics and economy of the nation. The economic dependence on cotton encouraged the economic and territorial expansion of the southern United States, particularly toward the western frontier, which led to a significant increase in cotton cultivation in the new territories. In summary, the origin of cultivated American cotton is rooted in its native species Gossypium hirsutum, which is indigenous to Mexico, Central America, and parts of South America. The domestication and eventual introduction of this cotton to the southeastern United States by Spanish colonizers has led to its significant expansion and influence on the US economy and society.
