Kennedy's opposition to slavery was first publicly expressed in his writings and later in his life as a politician through his speeches and political initiatives. His opposition to slavery in Maryland can be traced back through many decades of his life, but the depth of that opposition went through an evolution from milder and more understated in the beginning, to being stronger, more vocal and more morally based by the time of the
Emancipation Proclamation and then the following state-level effort to end slavery in Maryland, as the state was not included in the Emancipation Proclamation because it was not in the Confederacy. Kennedy once wrote that witnessing a speech by
Frederick Douglass had opened his eyes more fully to the "curse" of slavery, as Kennedy called it by 1863. Kennedy's 1830s novel
Swallow Barn is critical of slavery but also idealizes plantation life. However, the original manuscript shows that some of Kennedy's initial descriptions of plantation life were much more critical of slavery, but that he crossed those out of the manuscript before the book went to the printer, possibly because he was afraid of being too openly critical of slavery while living in Maryland, a slave state. The novel, although more muted in its criticism of slavery by the time of its publication and also expressing some idyllic stereotypes about plantation life, leads to the prediction that slavery would bring the Southern states to ruin.
Swallow Barn was published in 1832, 29 years before the start of the Civil War and long before anyone else was known to predict that the Southern and Northern states were headed for armed conflict.
Civil War Just prior to the Civil War, Kennedy wrote that abolishing slavery immediately was not worth full-scale civil war and that slavery should instead be ended in stages to avoid war. He noted that civil wars were historically the most bloody and devastating kinds of warfare and suggested a negotiated, phased approach to ending slavery to prevent war between the sections. But after the war broke out, he returned to a position of outright opposition to slavery and began to call for "immediate emancipation" of slaves. His demands for the end of slavery grew stronger as the war progressed. By the height of the Civil War, when Kennedy's opposition to slavery had become much stronger, he signed his name to a key political pamphlet in Maryland opposing slavery and calling for its immediate end. Since there was no active insurrection in Maryland, President Lincoln did not feel constitutionally authorized to extend the Emancipation Proclamation to Maryland. Only the state itself could end slavery at this point, and this was not a certain outcome as Maryland was a
slave state with strong Confederate sympathies. John Pendleton Kennedy and other antislavery leaders, therefore, organized a political gathering. On December 16, 1863, a special meeting of the Central Committee of the
Union Party of Maryland was called on the issue of slavery in the state. At the meeting,
Thomas Swann, a state politician, put forward a motion calling for the party to work for "Immediate emancipation (of all slaves) in Maryland". John Pendleton Kennedy spoke next and seconded the motion. Since Kennedy was the former speaker of the Maryland General Assembly, as well as a respected author, his support carried enormous weight in the party. A vote was taken and the motion passed. However the people of Maryland as a whole were by then divided on the issue and so twelve months of campaigning and lobbying on the matter of slavery continued throughout the state. During this effort, Kennedy signed his name to a party pamphlet calling for "immediate emancipation" of all slaves that was widely circulated. On November 1, 1864, after a year-long debate, a state referendum was put forth on the slavery question. The citizens of Maryland voted to abolish slavery, though only by a 1,000 vote margin, as the Southern part of the state remained heavily dependent on the slave economy. ==Work with cultural and educational institutions==
