Christiana Riot, The. The 1850 federal Fugitive Slave Act strengthened the position of slaveowners seeking to capture runaways. Pursuing four escaped slaves, Maryland farmer Edward Gorsuch arrived Sept. 11, 1851, at the Christiana home of William Parker, an African American who was giving them refuge. Neighbors gathered, fighting ensued, and Gorsuch was killed. This incident did much to polarize the national debate over the slavery issue.
