Brigadier General Robert Nugent was an Irish-born American U.S. Army officer during the American Civil War and the Indian Wars.

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."
