During the American Revolution, the Earl of Dunmore offered freedom to slaves in Virginia who joined British forces. Sir Henry Clinton’s 1779 Phillipsburg (NY) Proclamation went further, deeming all slaves in the new United States free and entitled to protection and land.

An act to explain and amend an act, entitled,
“An act for the gradual abolition of slavery.”

Dauphin County, Pennsylvania, Slave Records


Pennsylvania’s Gradual Abolition Act of 1780 did not free any slaves immediately. Instead, all slaves born prior to the law remained in bondage, while their children were free, but deemed indentured servants until age 28. The Dauphin County clerk required slaveholders to record the births of this new class of servant children, both to show compliance with the law and to provide evidence to such children of their free status.

The Haitian Revolution began in 1791 in the French colony of Saint-Domingue. By 1793, colonial officials sought an alliance with enslaved insurgents through local decrees that ultimately abolished slavery. In July 1793, a decree extended liberty to the families of insurgents turned soldiers, as set out here in a Haitian Creole broadside. Only later, in 1794, would the French National Convention in Paris ratify abolition throughout the French Empire. Napoleon Bonaparte’s re-instatement of slavery in 1802 would not affect Saint-Domingue, which would become the free and independent republic of Haiti in 1804.

While the British Empire banned the international slave trade in 1807, the Slavery Abolition Act of 1833 ended slavery itself.  Stephen Gimber’s print offers a powerful interpretation of this moment, through the figures of liberated slaves and the Act itself posted nearby. Gimber elided two elements of the act: former slaves were now bound to indentured service, many until 1840, and former slave owners were compensated 20 million pounds for the loss of their property.

It was not until 1865, with the ratification of the Thirteenth Amendment, that slavery was abolished in the United States. Abraham Lincoln’s 1863 Emancipation Proclamation was but one, partial step in the prolonged process of abolition in the Americas that unfolded between 1775 and 1888.

Abolition in Cuba began in 1880 with a decree of patronato, a form of indentured servitude that required former slaves to work for eight years. In 1886, slavery was finally abolished by a royal decree. Photographer George Barnard captured a group of enslaved African and Yucatecan Indian laborers in 1863. Shortly after taking this image, Barnard would return to the United States to join the ranks of Civil War field photographers.

Brazil was the last nation in the Americas to abolish slavery. In 1888, the Lei Áurea or Golden Law, formally ended legal bondage and liberated approximately 720,000 slaves. Here, Brazilian legislators gather to witness the signing of the new law, which had passed both houses of the National Assembly and was sanctioned by Isabel, Brazil’s Imperial Princess and Regent.
