Indigenous peoples and colonial period Before European colonization, the land comprising present-day South Williamsburg formed part of the ancestral territory of the
Canarsie and
Lenape peoples. When the Village of
Williamsburg annexed a portion of the Town of
Bushwick in 1835, it was organized into three districts; the first district was commonly called the "South Side," a designation that has persisted.
Nineteenth and early twentieth century development During the mid-nineteenth century, the waterfront developed into a major industrial zone. The Havemeyer & Elder Sugar Refinery, later known as the
Domino Sugar Refinery, opened in 1856 and grew to become the largest sugar-refining facility in the world. By 1870, Williamsburg produced a majority of the sugar consumed in the United States. German chemist
Charles Pfizer founded
Pfizer Pharmaceuticals in Williamsburg in 1849 and the company maintained an industrial plant in the neighborhood through 2007. The neighborhood's population during this period consisted primarily of German and Irish immigrants, followed by waves of Italian, Polish, and Eastern European Jewish arrivals. By the 1890s, South Williamsburg had become a major center of Eastern European Jewish immigration.
Post-World War II demographic shifts Following
World War II, South Williamsburg experienced profound demographic transformation. Williamsburg had already developed a substantial
Orthodox Jewish population in the decades after the Williamsburg Bridge opened, as religious Jews sought to escape the overcrowded
Lower East Side while remaining close to established synagogues and
kosher commerce. This existing infrastructure made the area south of Division Avenue attractive to the thousands of
Hasidic Jews, many of them
Holocaust survivors from Hungary and Romania, who settled there beginning in the late 1940s.
Rabbi Joel Teitelbaum of the
Satmar Hasidic dynasty arrived in the United States in 1947 and established Congregation
Yetev Lev in 1948, building what would become one of the largest
ultra-Orthodox Jewish communities in the United States. Under his leadership, the Satmar community revitalized abandoned housing stock and constructed
yeshivas,
mikvahs, and
synagogues throughout the 1950s and 1960s. . Simultaneously, Puerto Rican migrants began arriving in large numbers during the postwar decades in what became known as the "
Great Migration." By 1954, the New York City Youth Board reported that Puerto Ricans had established significant concentrations in South Williamsburg, representing a shift from earlier settlement patterns concentrated in Upper Manhattan. The Brooklyn Navy Yard's labor demands drew many Puerto Ricans to nearby Williamsburg in the 1940s and 1950s, and Graham Avenue became such a center of Puerto Rican life that it earned the nickname "Avenue of Puerto Rico." These newcomers settled primarily in the area south of Grand Street that would become known as Los Sures.
Urban decline and community organizing By the 1980s, an estimated 20,000 Puerto Ricans lived in the Southside neighborhood. The deindustrialization of the mid-twentieth century devastated South Williamsburg's Puerto Rican and Latino community. Manufacturing jobs disappeared as factories closed or relocated, and by the 1970s and 1980s, the neighborhood suffered from widespread poverty, abandoned buildings, fires, and rising crime. The Hasidic community experienced these decades differently. Having arrived after World War II when manufacturing was already beginning to decline, the community's economy had developed around serving its own religious and communal needs rather than industrial employment. Latino residents organized to address deteriorating conditions. In 1972, Puerto Rican and Latino residents established Southside United HDFC, commonly known as Los Sures, which became one of New York City's most influential tenant-led housing organizations. Los Sures rehabilitated abandoned buildings, created affordable housing cooperatives, and established cultural centers that preserved the neighborhood's identity. In 1975, it became Brooklyn's first community-based organization to enter agreements to manage city-owned properties.
El Puente, founded in 1982 by Luis Garden Acosta, Frances Lucerna, and Gino Maldonado, emerged as another influential community organization. Originally focused on combating gang and drug-related violence, El Puente developed into a human rights organization addressing education, arts, public health, and environmental justice issues affecting the Latino community. These organizations sometimes collaborated across ethnic lines. Leaders of
El Puente and UJO, along with other community nonprofits, created the Williamsburg Neighborhood Based Alliance to investigate housing, daycare, and healthcare issues affecting all residents. This coalition inspired the formation of the Community Alliance for the Environment (CAFÉ), which successfully organized opposition to a proposed 55-story incinerator at the Brooklyn Navy Yard that would have emitted hazardous chemicals into the atmosphere. El Puente's youth environmental group, the Toxic Avengers, campaigned to close Radiac, a radioactive waste facility, in 1992. A 2022 exhibit at El Museo de Los Sures and the Greenpoint Library,
"Our Voices Seen and Heard: 50 Years of Protest," commemorated the neighborhood's environmental activism history.
Gentrification and zoning changes Beginning in the 1990s and accelerating after 2000, South Williamsburg experienced dramatic change as artists and young professionals settled in the neighborhood. According to the
NYU Furman Center, Williamsburg and Greenpoint were the most rapidly
gentrifying neighborhoods in New York City between 1990 and 2014, with average rents rising 78.7 percent compared to 22.1 percent citywide. During that period, the Hispanic population fell by 12 percent while the white population grew by 9 percent. The neighborhood's two main communities responded differently to these changes. The Hasidic community viewed the influx of secular residents as a threat to their religious way of life and community cohesion. Latino organizations fought displacement through tenant advocacy, affordable housing development, and legal challenges. Despite opposition from both communities, the
New York City Council approved the Greenpoint-Williamsburg rezoning on May 11, 2005, converting 175 blocks to permit high-density residential development. The rezoning's demographic impact proved significant. Housing advocates documented that the Latino population declined by 27 percent while the white population increased by 44 percent in the years following the rezoning. == Geography ==
