Christiana Riot Trial

During the 1850s, Northern abolitionism developed, Southern defense of slavery hardened, and debates over the expansion of slavery gripped the nation. When pro-slavery and anti-slavery factions met at Christiana, Pennsylvania, a mere 20 miles north of the Mason-Dixon Line, the events that followed and the subsequent trial in Philadelphia became flashpoints that deepened the sectional divisions between the North and South.

The Christiana Riot took place at the home of William Parker, a free black man who helped organize a mutual protection society for the area’s African American population. When Edward Gorsuch and his posse arrived at Parker’s home, they were met by at least fifty men who intended to protect the escaped slaves. (Historical Society of Pennsylvania)

On September 11, 1851, slaveholder Edward Gorsuch (1795-1851) and his party of eight men rode into Christiana from Baltimore County, Maryland, with warrants for the arrests of four fugitive slaves. Upon reaching the home of William Parker (1822-?), a fugitive slave, Gorsuch and his party were met with armed resistance. A large group of armed black men and women surrounded Gorsuch’s party and demanded that they leave Pennsylvania immediately. When Gorsuch refused to vacate Parker’s property, chaos ensued. Indeed, Gorsuch’s men fired guns as black men and women attacked Gorsuch’s party with clubs, corn cutters, and other crude weapons. While accounts of that day conflict, numerous individuals on both sides of the battle were injured and Gorsuch died of wounds sustained during the fight.

In the immediate aftermath of the Christiana Riot, Parker and two other men, presumably fugitive slaves, escaped for Canada. U.S. officials hastily arrested anyone possibly connected with the riot, including a white miller from Christiana named Castner Hanway (1821-93). Hanway, who rode to Parker’s home on the day of the riot, was mistakenly identified as the mastermind of the riot. Along with forty-one other men, Hanway was charged with treason for “wickedly and traitorously” intending “to levy war” against the United States. Hanway’s trial began on November 24, 1851, at the old Pennsylvania State House in Philadelphia (Independence Hall) with Supreme Court Justice Robert C. Grier (1794-1870) and U.S. District Court Judge John K. Kane (1795-1858) presiding.

The Fugitive Slave Act of 1850 forced law enforcement officers in free states to help recapture escaped slaves. Under this law, Edward Gorsuch rode into Christiana with warrants for the recapture of four slaves, which led to the Christiana Riot. (Library of Congress)

The defense of the Christiana Riot participants became a popular cause for the abolitionist movement. Fiery abolitionist and U.S. representative for Lancaster County Thaddeus Stevens (1792-1868) led Hanway’s defense team, and abolitionist Lucretia Mott (1793-1880) sat in the courtroom on the second floor of Independence Hall throughout the trial. The prosecution was directed by the U.S. attorney for the Eastern District of Pennsylvania, John W. Ashmead (1806-68), and a team of lawyers from the state of Maryland. After opening arguments, Ashmead called the prosecution’s key witness, U.S. Deputy Marshal Henry Kline (1820-85), to the stand. Kline had been among Gorsuch’s party on the day of the riot and testified that Hanway was responsible for inciting Parker and the resisters. Under cross-examination, Kline admitted that he had hidden in a cornfield during the riot, so his view was obstructed. Following Kline’s testimony, the defense called twenty-nine character witnesses, including Judge William D. Kelley (1814-90), who portrayed Kline as a liar and a known kidnapper. This testimony was devastating for the prosecution. Indeed, for many Pennsylvanians—even those who were not in sympathy with the abolitionist cause—there was little interest in prosecution, because the 1850 Fugitive Slave Law seemed to represent an incursion of federal power into state sovereignty. After fifteen minutes of deliberation by the jury, Hanway was found not guilty of treason. Subsequently, federal and state officials declined to press further charges against the riot participants.

The verdict served as a fuel for the abolition movement as it gained momentum in the 1850s. The events at Christiana also showed that African American men and women could organize themselves to actively resist any attempts to kidnap fugitive slaves or disturb their communities. Nevertheless, Southerners viewed the verdict as a product of Northern radicalism and a failure to equally apply the law. The sectional divisions made clear by the Christiana Riot trial deepened throughout the 1850s and ultimately led to the Civil War.

  1. My great-great grandfather, Henry Green (1827 – 1911), was one of the 42 men arrested for his participation in the September 11, 1851 “Christiana Riot,” the first action prosecuted under the 1850 Fugitive Slave Act.

    What is interesting is that, in the stories passed via my family’s oral history surrounding the incident, the stories references are to “The Christiana Resistance” or “The Christiana Uprising.” As people living in a culture of honor, my forebears most likely felt that “riot” did not portray their staunch commitment to the abolition of slavery: they risked life, limb, and livelihood to free the slaves, harboring escaped slaves in local “safe houses” along the Underground Railroad.

    To say that Henry Green was involved in an action as chaotic and disorderly as a “riot” is like characterizing the Battle of Gettysburg as a street fight . My Welsh Mountain forebears saw what they were doing, rescuing slaves from bondage, as not only strategic and tactical operations but also morally right action, part of their Christian duty. In 1864, moved by his commitment to abolishing slavery, Henry Green marched out of Lancaster with the 41st U.S. Colored Troops to fight in Virginia. He was present at the Appomattox Courthouse on April 5, 1865 to witness Lee’s surrender to Grant, thus his lifelong fight to abolish slavery, his resistance to coercive and immoral police actions, had come full circle.
