 Cuba had slave revolts in 1795, 1798, 1802, 1805, 1812 (the Aponte revolt), 1825, 1827, 1829, 1833, 1834, 1835, 1838, 1839–43 and 1844 (the La Escalera conspiracy and revolt).Vincent Brown, a professor of History and of African and African-American Studies at Harvard, has made a study of the Transatlantic Slave Trade.In 2013, Brown teamed up with Axis Maps to create an interactive map of Jamaican slave uprisings in the 18th century called, “Slave Revolt in Jamaica, 1760-1761, A Cartographic Narrative.” Brown's efforts have shown that the slave insurrection in Jamaica in 1760-61 was a carefully planned affair and not a spontaneous, chaotic eruption, as was often argued (due in large part to the lack of written records produced by the insurgents).
