Boston Central Labor Union is established.

Originally the Workingmen’s Central Union, it is formed by several building trades, boot and shoe workers, printers, tailors, hatters, iron molders, and harness makers at the suggestion of the Boston Typographical Union. The second oldest central labor union in the U.S., its goals are “to encourage all legislation for the benefit of working men; aid in the enforcement of present laws in the interest of labor which are evaded or carried out in a loose or improper manner; watch all proposed legislation in the councils of the city or state; and use its best efforts for the promotion of the general good.” By 1913, it has 35 locals and over 96,000 members. By 1930, it includes 150 local unions and 80,000 workers in the Boston area.
