The Great Strike refers to a significant labor action that took place in the United States during the summer of 1877. It began as a response to wage cuts and poor working conditions in the railroad industry, particularly affecting the Baltimore and Ohio Railroad. Workers across multiple states joined in protests, leading to widespread disruptions in rail service. The strike escalated into violent confrontations between workers and law enforcement, resulting in numerous deaths and injuries. It marked a pivotal moment in U.S. labor history, highlighting the growing tensions between labor unions and industrial management, and setting the stage for future labor movements.
