The slaves of Antioquia, studied in this chapter, experienced a constant tension between captivity and geographic mobility. Many easily and frequently talked to other slaves and to free people, sharing their hopes that an end of slavery was possible. Slave leaders tried collectively to press for the end of their enslavement. After Antioquia’s transformation into a republic devoted to individual freedom in 1812, slave leaders emerged as the first critics of the founding documents and legal principles of this new polity. Felix José de Restrepo and other members of Antioquia’s independent government partially listened to those criticisms. They amalgamated experiences and perspectives that were first developed in Cartagena and Popayán, inviting revolutionary colleagues to consider that legislators and forward-looking governments had an obligation to favor freedom over slavery. Antioquia passed Colombia’s first antislavery law in 1814. Based on the free womb principle, the law was correctly understood by slaves as a legal act with limitations and ambivalences. But the Spanish Restoration of 1816 halted this law and all other antislavery and anti-Spanish initiatives.
