The roots of our country's trade unions extend deep into the early history of America. Primitive unions, or guilds, of carpenters, cabinet makers and cobblers made their appearance, often temporary, in various cities along the Atlantic seaboard of colonial America. Workers played a significant role in the struggle for independence; carpenters disguised as Mohawk Indians were the "host" group at the Boston Tea Party in 1773. The Continental Congress met in Carpenters Hall in Philadelphia, and there the Declaration of Independence was signed in 1776. In "pursuit of happiness" through shorter hours and higher pay, printers were the first to go on strike, in New York in 1794; cabinet makers struck in 1796; carpenters in Philadelphia in 1797.

As ineffective as these first efforts to organize may have been, they reflected the need of working people for economic and legal protection from exploiting employers. The invention of the steam engine and the growing use of water power to operate machinery were developing a trend toward a factory system not much different from that in England which produced misery and slums for decades. Starting in the 1830s and accelerating rapidly during the Civil War, the factory system accounted for an ever-growing share of American production. It also produced great wealth for a few, grinding poverty for many.
With workers recognizing the power of their employers, the number of local union organizations increased steadily during the mid-19th century. In a number of cities, unions in various trades joined together in citywide
