The Impossible Rise of Manhattan: From Dangerous Island to $1 Trillion GDP Powerhouse

In 1626, the Dutch traded sixty guilders' worth of goods for a narrow, rocky island at the mouth of the Hudson River. Four hundred years later, that island — Manhattan — produces a GDP of one trillion dollars, more than most sovereign nations. This is the story of how it got from one number to the other. It moves through the Dutch trading post and the wall that became Wall Street, the Erie Canal and the commercial explosion it unleashed, the Great Fire of 1835 that leveled Lower Manhattan's financial district and forced the city to rebuild in stone, the Five Points slum where cholera and violence coexisted with the invention of tap dancing and machine politics, the Draft Riots of 1863 that left Manhattan under martial law, Boss Tweed's Tammany Hall, the Gilded Age mansions on Fifth Avenue, the Triangle Shirtwaist fire, the opening of the subway, the skyscraper race between Walter Chrysler and the builders of the Empire State Building, the postwar exodus to the suburbs, the near-bankruptcy of 1975, and the long, uneven recovery that turned Manhattan real estate into the most expensive ground in America. Through all of it, one fact holds: the same forces that made the island dangerous — the density, the immigration, the physical constraints of a place barely two miles wide — are the ones that made it rich.
