Who invented the cotton gin and in what year did they invent it?
A primitive cotton gin was invented in India in the 5th century known as a charkhi. This invention was eventually innovated into a foot powered and water powered machine. This was only effective for processing the varieties of cotton grown in India and the middle east. Eli Whitney invented the modern cotton gin in 1792. This gin was more effective at separating the seeds from green seed cotton, a variety often grown in the south-eastern United States. Cotton gins are used to hold the cotton.

The gin method for seeding cotton can be traced back as far as the first century AD. The earliest versions consisted of a single roller made of iron or wood and a flat piece of stone or wood. Evidence for this type of gin has been found in Africa, Asia, and North America. The first documentation of the cotton gin by contemporary scholars is found in the fifth century AD. Visual evidence of the single-roller gin exists in the form of fifth-century Buddhist paintings in the Ajanta Caves in western India. These early gins were difficult to use and required a great deal of skill. A narrow single roller was necessary to expel the seeds from the cotton without crushing the seeds. The design was similar to that of a metate, which was used to grind grain. The modern cotton gin was created by the American inventor Eli Whitney in 1793 to mechanize the cleaning of cotton. The invention was granted a patent on March 14, 1794. There is slight controversy over whether the idea of the cotton gin and
The modern cotton gin was created by the American inventor Eli Whitney in 1793 to mechanize the cleaning of cotton. The invention was granted a patent on March 14, 1794. There is slight controversy over whether the idea of the cotton gin and its constituent elements are correctly attributed to Eli Whitney. The popular version of Whitney inventing the cotton gin is attributed to an article on the subject in the early 1870s and later reprinted in 1910 in the The Library of Southern Literature. In this article the author mentioned how Catherine Littlefield Greene suggested to Whitney the use of a brush-like component instrumental to separate out the seeds and cotton. Because social norms inhibited women from registering for patents, Eli Whitney received the patent-and the sole credit in history textbooks until recently. Sources: http://en.wikipedia.
