Anger arose about conscription, with resentment at those who could afford to pay $300 to avoid service leading to resentment against Lincoln's war policies and fomenting paranoia about free Blacks taking the poor immigrants' jobs, culminating in the three-day-long New York Draft Riots of July 1863. These intense war-time riots are counted among the worst incidents of civil disorder in American history, with an estimated 119 participants and passersby massacred. The rate of immigration from Europe grew steeply after the Civil War, and Manhattan became the first stop for millions seeking a new life in the United States, a role acknowledged by the dedication of the Statue of Liberty on October 28, 1886, a gift from the people of France. New York's growing immigrant population, which had earlier consisted mainly of German and Irish immigrants, began in the late 1800s to include waves of impoverished Italians and Central and Eastern European Jews flowing in en masse. This new European immigration brought further social upheaval. In a city of tenements packed with poorly paid laborers from dozens of nations, the city became a hotbed of revolution (including anarchists and communists among others), syndicalism, racketeering, and unionization. In 1883, the opening of the Brooklyn Bridge established a road connection to Brooklyn, across the East River. In 1874, the western portion of the present Bronx County was transferred to New York County from Westchester County, and in 1895 the remainder of the present Bronx County was annexed. In 1898, when New York City consolidated with three neighboring counties to form "the City of Greater New York", Manhattan and the Bronx, though still one county, were established as two separate boroughs.

In the 1920s Manhattan experienced large arrivals of African-Americans as part of the Great Migration from the southern United States, and the Harlem Renaissance, part of a larger boom time in the Prohibition era that included new skyscrapers competing for the skyline.
