Which of the following was a significant labor conflict during the era of industrialization?

The Pullman Strike was a significant labor conflict during the era of industrialization, primarily occurring in 1894. It was rooted in disputes over wages and working conditions at the Pullman Company, which manufactured railroad cars. As the company cut wages while maintaining high rents in company-owned housing, workers organized a strike to protest these conditions. The strike ultimately spread nationwide, disrupting rail traffic and leading to federal intervention, which highlighted the growing tensions between labor and management during this period of rapid industrial growth. The Pullman Strike also set the stage for future labor movements and highlighted the need for better labor laws and protections for workers, marking it as a crucial event in American labor history.

In contrast, the other options pertain to different historical contexts: the Boston Tea Party was a political protest against British taxation in 1773, the Great Awakening refers to a series of religious revivals in the 18th and early 19th centuries, and the War of 1812 was a military conflict between the United States and Britain over maritime rights. These events do not relate to labor conflicts or the industrialization era directly.
