A large multi-state railroad strike led by the Knights of Labor began against railroads associated with Jay Gould; its defeat contributed to the Knights’ weakening and the growing appeal of craft unionism.
A labor rally supporting the eight-hour day ended in violence after a bomb was thrown at police, intensifying repression and public backlash and accelerating shifts in U.S. labor organizing.

Congress passed and President Woodrow Wilson signed the first major federal law restricting child labor via interstate commerce controls (later struck down by the Supreme Court).
The Adamson Act set an eight-hour workday (with overtime pay) for interstate railroad workers, a major federal intervention to avert a national rail strike and advance hours reform.
The Transportation Act of 1920 reorganized rail regulation after wartime control and established the Railroad Labor Board to address wage disputes, shaping federal labor relations in rail through the 1920s.
AFL president Samuel Gompers died in 1924 after decades of leadership that emphasized craft unionism and collective bargaining focused on wages, hours, and working conditions.
