Rising anti-Catholic sentiment toward Irish Catholic immigrants, combined with a false nativist rumor spread over five months that Catholics sought to remove the Bible from public schools, created intense communal tension in Philadelphia and its surrounding districts of Kensington and Southwark.
Beginning May 6, 1844, a nativist rally in Kensington turned violent, sparking three days of rioting that destroyed two Catholic churches and many buildings. In July, discovery that St. Philip Neri's Church had armed itself triggered renewed fighting between nativists and militia, resulting in further deaths and injuries across Southwark.
The riots prompted the Catholic Church to sue Philadelphia successfully for repair costs. Civic leaders condemned nativist violence, and the events fueled national criticism of the nativist movement. Deficiencies in law enforcement were exposed, driving police reforms and ultimately the consolidation of Philadelphia and its surrounding districts into one city in 1854.
Political Outcome
Nativist rioters suppressed by militia; Catholic Church won damages in court; riots spurred police reform and Philadelphia's eventual consolidation in 1854.
