On the night of August 17, 1823, the distinctly African sounds of blaring shell-horns and beating drums signalled the start of one of the most massive slave rebellions in the history of the Western hemisphere, the uprising in the British colony of Demerara (now Guyana). That evening, nine to twelve thousand slaves surrounded the main houses of about sixty plantations, armed with cutlasses, knives fastened on poles, and guns.

They broke down doors, smashed windows, commandeered arms and ammunition, and put their masters and overseers in the stocks. Intent on avoiding a blood bath (over three days of fighting, colonial forces took the lives of more than 255 slaves, while only two or three white men were killed), the rebels spoke of "rights", and planned to present their grievances to the governor. For a few days, the slaves succeeded in turning the world upside down, treating masters the way masters had always treated slaves.

Retaliation from colonial officials would be swift, bloody, and brutal.

In Crowns of Glory, Tears of Blood Emilia Viotti da Costa tells the riveting story of a pivotal moment in the history of slavery. Studying the complaints brought by slaves to the office of the Protector of Slaves, she reconstructs the experience of slavery through the eyes of the Demerara slaves themselves.

Da Costa also draws on eyewitness accounts, official records, and private journals (most notably the diary of John Smith, one of four ministers sent by the London Missionary Society to convert Demerara's "heathen"), to paint a vivid portrait of a society in transition, shaken to its foundations by the recent revolutions in America, France, and Haiti.

Smith and his wife, Jane, the planters and colonial politicians, and the leaders of the rebellion emerge as flesh-and-blood individuals, players trapped in a complex political game none of them could fully understand.
