Union City is a city in the northern part of Hudson County, New Jersey, United States. Union City was incorporated as a city by an act of the New Jersey Legislature on June 1, 1925, with the merger of Union Hill and West Hoboken Township. The city's name marks the combination of the two municipalities. Two major waves of immigration, first of German speakers and then of Spanish speakers, greatly influenced the development and character of Union City. Its two nicknames, "Embroidery Capital of the United States" and "Havana on the Hudson", reflect important aspects of that history. Thousands visit Union City each year to see the nation's longest-running passion play and the annual Cuban Day Parade of New Jersey. The city is notable for being the location where Mallomars were first sold and the site of the first lunch wagon built by Jerry and Daniel O'Mahoney and John Hanf, which helped spark New Jersey's golden age of diner manufacturing, for which the state is colloquially referred to by author Richard J.S. Gutman as the "diner capital of the world".
Bergenline Avenue is the city's main commercial thoroughfare. Currently the longest commercial avenue in the state, boasting over 300 retail stores and restaurants, Bergenline runs through not only the entire length of Union City from north to south, but also through West New York, Guttenberg and North Bergen, making it the main commercial strip for Northern Hudson County. Also known as the "Miracle Mile", Bergenline's largest concentration of retail and chain stores begins at the intersection of 32nd Street and continues north until 92nd Street in North Bergen, and while it is a narrow one-way, southbound street throughout most of Union City, it becomes a four lane, two-way street at 48th Street, one block south of the town's northern boundary. Bergenline Avenue is also used as the route for local parades, such as the annual Memorial Day Parade. At Union City's southern end, Bergenline is primarily a residential street, with the shopping district concentrated at Summit Avenue and Transfer Station. The neighbourhood was also the site, in 1912, of the first lunch wagon which helped spark New Jersey's so-called "golden age of diner manufacturing", which in turn made the state the informal "diner capital of the world". In the decades that followed, nearly all major U.S. diner manufacturers, including Jerry O'Mahoney Inc., started in New Jersey. During World War II, the area was a 24-hour hotspot for U.S. servicemen, who patronised the dozens of night-clubs located there.
In terms of business, Union City is notable for being the location where Mallomars were first sold. Nabisco sold them to a grocer in the southern half of the town, when it was West Hoboken.
