The International Juridical Association (IJA; 1931–1942) was an association of socially minded American lawyers, established by Carol Weiss King and considered by the U.S. federal government (in the form of the U.S. House Un-American Activities Committee or HUAC) as "another early (communist) front for lawyers. The principal concern about the IJA (and, as of 1942, its successor group, the National Lawyers Guild or NLG) was that it "constituted itself an agent of a foreign principal hostile to the interests of the United States."

14th Street is a major crosstown street in the New York City borough of Manhattan, traveling between Eleventh Avenue on Manhattan's West Side and Avenue C on Manhattan's East Side. It forms a boundary between several neighborhoods and is sometimes considered the border between Lower Manhattan and Midtown Manhattan. At Broadway, 14th Street forms the southern boundary of Union Square. It is also considered the northern boundary of Greenwich Village, Alphabet City, and the East Village, and the southern boundary of Chelsea, Flatiron/Lower Midtown, and Gramercy. West of Third Avenue, 14th Street marks the southern terminus of western Manhattan's grid system. North of 14th Street, the streets make up a near-perfect grid that runs in numerical order. South of 14th, the grid continues in the East Village almost perfectly, but not so in Greenwich Village, where an older and less uniform grid plan applies. In the early history of New York City, 14th Street was an upscale location. However, it lost its glamour and status as the city grew northward and today it is primarily zoned as a commercial street. In October 2019, a busway restriction was put in place between Third and Ninth Avenues, prohibiting most types of vehicles during the daytime.

15 Union Square West is a residential building on East 15th Street overlooking Union Square in Manhattan, New York City. Originally Tiffany & Company’s 19th-century headquarters, it was refurbished and reopened in 2008 as high-end apartments. Commissioned by Charles Lewis Tiffany in 1869, John Kellum designed the original structure, which included 16-foot cast-iron arches that rose above the park. The building cost $500,000 and opened in 1870. At the time, the store was described as “the largest of its kind devoted to this business of any in the world,” and dubbed the “palace of jewels”. Tiffany & Co. stayed there until 1906. By 1925 the building was occupied by the Amalgamated Clothing Workers of America trade union. By 1952 it was owned by Amalgamated Bank. After a fatal accident where a pedestrian was struck by a falling piece of cast iron, they stripped the original façade and covered it with white brick. The building then stood unchanged for more than 50 years.Brack Capital Real Estate purchased the property in 2006, and restored the original six-story structure and added six newly constructed floors to create a boutique condominium with 36 residences. The brick façade was dismantled and the original arches were reconditioned and wrapped behind a façade of glass and black anodized aluminum. The original structure was topped by an additional six stories of all glass residences. Designed by Eran Chen of ODA-Architecture, previously of Perkins Eastman, the building blends historic and contemporary elements.In 2011, two of the two-bedroom apartments were purchased by tennis player Caroline Wozniacki for $9 million. Earlier that year, the retail portion of the development was purchased by the State Teachers Retirement System of Ohio (STRS) for $57.88 million.

The New York Workers School, colloquially known as "Workers School", was an ideological training center of the Communist Party USA (CPUSA) established in New York City for adult education in October 1923. For more than two decades the facility played an important role in the teaching of party doctrine to the organization's functionaries, as well as offering a more general educational program to trade union activists. The Workers School was a model for local CPUSA training centers in the area (e.g., the Jewish Workers University, founded in New York City in 1926) and in other American cities (e.g., the Chicago Workers School). It also provided the direct inspiration for the New Workers School, established by the breakaway Communist Party (Majority Group) headed by Jay Lovestone and Benjamin Gitlow (supported by Bertram D. Wolfe and Ben Davidson) after they left the Communist Party in 1929. The Workers School was dissolved through merger in 1944, becoming part of the CPUSA's Jefferson School of Social Science.
