America's Comfort Women
Referring to the "the mass rape of female African-American slaves during the ante-bellum period," The Marmot's Hole today links to this thought-provoking article: In criticizing Japan's history textbooks, Americans should think twice.

Many were bought and sold in the "fancy-girl markets" described below, from The Economics of the Slave Trade:

The establishment of what have been called "fancy-girl" markets is one example of this. Some big cities, like New Orleans and Louisville had special markets where "girls, young, shapely, and usually light in color, went as house servants with special services required." These slaves were officially sold as house servants, but both buyers and sellers understood that sexual motivation lay behind the purchase and the (forced or consentual) sexual service of female slaves was really being sold. These girls could be sold for as much as $5000 at the same time that skilled male laborers were valued at only half as much. The special nature of these sales made the "fancy girl" markets a very glaring example of how as the slave system expanded in the antebellum period, there was much more than a economic labor market involved in the trading of slaves.

Reverend Henry Ward Beecher's church bought a group of such girl destined for a "fancy-girl market" out of slavery and his famous sister took responsibilty for their education, as she details in this letter: Harriet Beecher Stowe to Mrs. Cowles, 4 August 1852.
