The Ludlow Street Jail was New York City's Federal prison, located on Ludlow Street and Broome Street in Manhattan.

Thomas Nast was a German-born American caricaturist and editorial cartoonist often considered to be the "Father of the American Cartoon". He was a critic of Democratic Representative "Boss" Tweed and the Tammany Hall Democratic party political machine. Among his notable works were the creation of the modern version of Santa Claus and the political symbol of the elephant for the Republican Party (GOP). Contrary to popular belief, Nast did not create Uncle Sam, Columbia, or the Democratic donkey, although he did popularize those symbols through his artwork. Nast was associated with the magazine Harper's Weekly from 1859 to 1860 and from 1862 until 1886.

Tammany Hall, also known as the Society of St. Tammany, the Sons of St. Tammany, or the Columbian Order, was a New York City political organization founded in 1786 and incorporated on May 12, 1789, as the Tammany Society. It became the main local political machine of the Democratic Party, and played a major role in controlling New York City and New York State politics and helping immigrants, most notably the Irish, rise in American politics from the 1790s to the 1960s. It typically controlled Democratic Party nominations and political patronage in Manhattan after the mayoral victory of Fernando Wood in 1854, and used its patronage resources to build a loyal, well-rewarded core of district and precinct leaders; after 1850 the vast majority were Irish Catholics due to mass immigration from Ireland during and after the Irish Famine.
