Originally settled by the Dutch in the 17th century as Pavonia and later Bergen, Jersey City was incorporated in 1838 and expanded significantly on May 3, 1870, when it annexed Bergen City and Hudson City following a special election to form "Greater Jersey City." The city has transformed into a major finance and banking hub nicknamed "Wall Street West" following waterfront redevelopment, and has been recognized by Travel + Leisure as the best place to live in New Jersey in 2023 and 2025, with attractions including Liberty Science Center, Ellis Island, the Loew's Jersey Theatre, and Liberty State Park.

The city was officially named New Barbadoes Township until 1921, though it has been informally known as Hackensack since at least the 18th century, derived from the Lenni Lenape word for "stony ground"; Chief Oratam deeded the land to the Dutch in 1665. With a 2020 census population of 46,030 - the city's highest ever and a 7% increase from 2010 - Hackensack has grown from 42,677 residents in 2000.
