Know Nothing Riot of 1856 The Know Nothing Riot of 1856 was a violent eruption linked to the Know Nothing movement and the American Party during the volatile mid-1850s in Baltimore, Maryland. It occurred amid intense political competition involving the Democratic Party, Whig Party, Free Soil Party, and emergent Republican Party, intersecting with national controversies such as the Kansas–Nebraska Act, the Dred Scott v. Sandford political climate, and debates over immigration to the United States. The riot became a focal point for conflicts among native-born Protestants, Catholic immigrants, municipal authorities, and federal actors.

Background and Causes

The riot emerged from long-standing tensions rooted in nativist ideology promoted by the Know Nothing movement and institutional anxiety within the American Party about the electoral influence of Irish Americans and German Americans. Political displacement following the collapse of the Second Party System and the realignment involving the Whig Party and Free Soil Party intensified rivalry with the Democratic Party, while national disputes such as the Kansas–Nebraska Act and disputes involving slaveholding states amplified partisan mobilization. Hostility to Roman Catholicism and organizations like Tammany Hall combined with militia preparedness exemplified by Mexican–American War veterans and municipal police forces set the stage for confrontation. Urban tensions in Baltimore were further exacerbated by competition between newspaper proprietors such as Alexander del Mar-era editors, street gangs like the Plug Uglies, and municipal officials including mayors and sheriffs drawn from rival party machines.

Timeline of Events

The timeline began on election day in 1856, when planned electoral meetings of the American Party and rival factions in Baltimore escalated into street clashes involving militia units, armed volunteers, and organized gangs. Early disturbances saw skirmishes near polling places and wards controlled by political bosses linked to Tammany Hall-aligned networks and Know Nothing precinct captains. Subsequent episodes included attacks on party headquarters, assaults on editors associated with The Sun (Baltimore) and other partisan presses, and confrontations involving state militia commanded by officers with prior service in the Mexican–American War and veterans of the United States Army. As violence spread, municipal institutions such as the mayor’s office and city police were overwhelmed, prompting appeals to the Maryland Militia and federal authorities in Washington, D.C..

Key Figures and Participants

Prominent participants comprised leaders and operatives of the American Party and the Know Nothing movement, local Democratic operatives, immigrant community leaders among Irish Americans and German Americans, and militia commanders with ties to national actors. Notable municipal figures included mayors, sheriffs, and aldermen who had affiliations with the Democratic Party or the American Party; press figures from outlets like The Sun (Baltimore), Baltimore American, and partisan weeklies played central roles. Street-level actors included leaders of gangs such as the Plug Uglies, Rip Raps, and Baltimore Fire Company auxiliaries; clergy from Roman Catholicism and Protestant denominations intervened in relief and mediation. Legal authorities included judges from the Maryland Court of Appeals and prosecutors who later handled indictments linked to the disturbances.

Casualties, Damage, and Immediate Aftermath

The riot produced fatalities, injuries, and property destruction concentrated in contested wards and near polling venues, with damage inflicted on storefronts, printing offices, and private residences associated with targeted communities. Hospitals and charitable institutions, including St. Mary’s Hospital and religious charities run by Sisters of Charity affiliates, treated wounded civilians. Immediate aftermath efforts involved city officials petitioning for additional militia deployments, clerical appeals from Catholic bishops and Protestant ministers calling for calm, and community-driven relief organized by ethnic societies and mutual aid associations such as Friendly Sons of St. Patrick and German immigrant benevolent societies.

Legal and Political Consequences

Legally, the riot precipitated prosecutions in state courts, grand jury investigations, and municipal inquiries that implicated members of the American Party, gang leaders, and certain law enforcement officers; cases were adjudicated in venues including the Maryland Court of Appeals and trial courts. Politically, the disturbance accelerated the decline of the American Party in urban politics, reshaped ward alignments controlled by Tammany Hall-style machines, and influenced national party strategies for the 1856 United States presidential election involving candidates such as Millard Fillmore, James Buchanan, and John C. Frémont. The event also informed legislative debates in state legislatures and municipal reforms aimed at policing, ballot security, and naturalization law administered under existing United States naturalization law precedents.

Public Reaction and Media Coverage

Contemporary newspapers and periodicals provided extensive coverage, with partisan dailies and weeklies like The Sun (Baltimore), Baltimore American, Harper's Weekly, The New York Times, and immigrant presses offering divergent narratives. Editorials by prominent journalists and pamphleteers debated responsibility among Know Nothing organizers, Democratic ward bosses, and law enforcement; cartoons and illustrated presses depicted scenes echoing imagery common in publications such as Harper's Weekly and Frank Leslie's Illustrated Newspaper. National commentary from papers in Philadelphia, New York City, Boston, and Cincinnati connected the riot to broader debates over nativism, immigration policy, and party realignment, while sermons and pamphlets by clergy and civic reformers urged institutional remedies.
