Mulberry Bend in the Five Points neighborhood around 1872, Board of Health.|alt= At the height of Five Points' inhabitation, only parts of
London's East End were equivalent in the Western world for population density,
child and infant mortality, disease, violent crime, unemployment, prostitution, and other classic problems of the urban destitute. It is sometimes considered the original American
melting pot, at first consisting primarily of newly emancipated Black Americans (gradual emancipation led to the end of outright enslavement in New York on July 4, 1827) and ethnic Irish, who had a small minority presence in the area since the 1600s. The local politics of "the Old Sixth ward" (The Points' primary municipal voting district), while not free of corruption, set important precedents for the election of Catholics to key political offices. Before that time, New York, and the United States at large, had been governed by the Anglo-Protestant founders. Although there were many tensions between Black Americans and the Irish, their cohabitation in Five Points was the first large-scale instance of voluntary racial integration in American history. Gradually, this African-American community moved to Manhattan's West Side and to undeveloped lands on the north end of the island in
Harlem by the early 20th century and across the
Harlem River into the
South Bronx, as the city developed northward. in the Five Points neighborhood (documented by
Jacob Riis, c. 1896) looking north from just above Cross Street. The tenements on the left were razed to create Mulberry Bend Park (now
Columbus Park). The two tenements visible on the right, 46
Mulberry Street () in the foreground, and 48-50 Mulberry Street on the Bend, are still there. Five Points is alleged to have had the highest murder rate of any slum at that time in the world. According to an old New York
urban legend, the
Old Brewery, formerly Coulthard's Brewery from the 1790s, then an overcrowded tenement on Cross Street housing 1,000 poor, is said to have had a murder a night for 15 years, until its demolition in 1852. Italians first settled in the Five Points in the 1850s. The parish of the Church of the Transfiguration at 25 Mott Street was largely Italian by the 1880s. Mulberry Bend, named for the curve in Mulberry Street in the Chatham District, became the heart of
Little Italy, which at its most populated was bordered on the south by Worth Street, on the east by the Bowery, and on the west by West Broadway. The Italian journalist
Adolfo Rossi and editor of New York's Italian language newspaper
Il Progresso Italo-Americano described the area around 1880: "Almack's" (also known as "Pete Williams's Place"), an African American-owned dance hall located at 67 Orange Street in Mulberry Bend (today Baxter Street), just south of its intersection with Bayard Street, was home to a fusion of Irish
reels and
jigs with the African
shuffle. Though different ethnic groups interacted in other parts of the United States as well, creating new dance and music forms, in New York this music and dance had spontaneously resulted on the street from competition between African-American and Irish musicians and dancers. It spilled into Almack's, where it gave rise in the short term to
tap dance (see
Master Juba) and in the long term to a music hall genre that was a major precursor to
jazz and
rock and roll. This ground is now Columbus Park. == Infectious diseases ==
