On 1 September 1934 millions of cotton spindles stopped spinning.
Across the Southern Piedmont mill whistles blew, but workers didn't come to work. The most exploited industrial workforce in the US - the 'lint heads' of the Carolinas, Tennessee, Georgia and Alabama - was on strike.
As mill owners appealed frantically for injunctions, teargas and the National Guard, a vast peaceful army of textile workers demolished the image of Southern labour as culturally servile and unorganisable. With voices honed to spare beauty in the choirs of mountain Baptist churches, they sang powerful hymns of solidarity instead.
