The 14th Indiana Infantry Regiment, later referred to as the Gallant Fourteenth, was an infantry regiment and part of the Union Army's celebrated "Gibraltar Brigade" of the Army of the Potomac during the American Civil War. Organized in May 1861 at Camp Vigo, near Terre Haute, Indiana, it was the state's first regiment organized for three years of service. The 14th Indiana served in major campaigns and battles in the Eastern Theater, mostly in West Virginia, Virginia, Pennsylvania, and Maryland. During its three years of service, the regiment had a total of 222 casualties.

The New York City draft riots, sometimes referred to as the Manhattan draft riots and known at the time as Draft Week, were violent disturbances in Lower Manhattan, widely regarded as the culmination of working-class discontent with new laws passed by Congress that year to draft men to fight in the ongoing American Civil War. The riots remain the largest civil and most racially charged urban disturbance in American history. According to Toby Joyce, the riot represented a "civil war" within the city's Irish community, in that "mostly Irish American rioters confronted police, [while] soldiers, and pro-war politicians ... were also to a considerable extent from the local Irish immigrant community."
