Know-Nothing candidate Thomas Swann was elected Mayor of Baltimore in 1856 amidst violence and a heavily disputed ballot.

The Know-Nothing Riot of 1856 occurred in Baltimore in the fall of 1856. Street tensions had escalated sharply over the preceding half-dozen years as neighborhood gangs, most of them operating out of local firehouses, became increasingly involved in party politics. Know-Nothing candidate Thomas Swann was elected Mayor of Baltimore in 1856 amidst violence and a heavily disputed ballot.



The American Party, also known as Know Nothings, had gained control of the local government in Baltimore during the October 1854 municipal election, making Samuel Hinks mayor and winning a majority in the Baltimore City Council. The party lost ground at the subsequent municipal election the following year. In 1856, both the Americans and their Democratic Party rivals girded for the coming contests.

1856 mayoral electionEdit

The campaign season opened with a deadly September confrontation between American Party members and Democrats on Federal Hill. Partisans battled over the following weeks.

In October 1856 the Know Nothing Mayor Samuel Hinks was pressed by Baltimorians to order General George H. Steuart's militia in readiness to maintain order during the mayoral elections, as violence was anticipated. Mayor Hinks duly gave Steuart the order, but he soon rescinded it.[1]

As a result, during the October municipal election, serious violence broke out on polling day, with shots exchanged by competing mobs.[1] In the 2nd and 8th wards several citizens were killed, and many wounded.[2] In the 6th ward artillery was used, and a pitched battle fought on Orleans St between Know Nothings and rival Democrats, raging for several hours.[2]

The Rip Raps a Nativist criminal gang clashed with the Democratic rowdies of the New Market Fire Company at Lexington Market. The Plug Uglies another Nativist criminal gang fought with Democrats in the Eighth Ward, which was popularly known as "Limerick" because of its large Irish population. Five partisans died in the combat, including an American who had come up from Washington, D.C. The result of the mayoral election, in which voter fraud was widespread, was a victory for the Know Nothings by around 9,000 votes.[2]

The partisans involved were overwhelmingly well-known fighting men with deep connections to the street violence of the fire companies. During the fighting at Lexington Market, Rip Raps specifically targeted the house of Petty Naff, the New Market's most notorious rowdy.

Legacy and continuing violenceEdit

In 1857, fearing similar violence at the upcoming elections, Governor Thomas W. Ligon ordered Steuart to hold the First Light Division, Maryland Volunteers in readiness. However, Mayor Thomas Swann successfully argued for a compromise measure involving special police forces to prevent disorder, and Steuart's militia were stood down. This time, although there was less violence than in 1856, the results of the vote were again compromised, and Swann was re-elected in a heavily disputed ballot.[3]
