What major event occurred in 1914 that involved the oppression of miners?

The Ludlow Massacre, which occurred in 1914, was a significant and tragic event involving the oppression of miners. It took place in Colorado and was a culmination of escalating tensions between coal miners who were striking for better working conditions, pay, and union recognition, and the Colorado National Guard, which was acting on behalf of the coal companies. The miners and their families had set up a tent city in Ludlow to support their strike, enduring harsh conditions in pursuit of their rights.

On April 20, 1914, violence erupted when the National Guard attacked the tent city. The conflict resulted in numerous deaths, including women and children, highlighting the brutal tactics used by the authorities against labor activists. This event is often seen as a watershed moment in labor history in the United States, drawing national attention to the struggles of workers and the need for reform.

Understanding the Ludlow Massacre is essential as it exemplifies the serious social and labor issues of the time, making it a key event in the history of labor relations in America. It distinguishes itself clearly from other events in the options provided, such as the Great Depression, which was an economic downturn, and World War I, a global conflict that did not directly pertain to the miners
