Final Answer:
Aside from Northern white men, urban industrial workers found common cause with the Republican Party (option c).
Step-by-step explanation:
During the late 19th and early 20th centuries, the Republican Party, particularly under President Abraham Lincoln, attracted support from various groups beyond Northern white men. Urban industrial workers, comprising a diverse demographic including immigrants and laborers, found common cause with the Republican Party. This alignment was driven by the party's advocacy for economic policies that supported industrialization and workers' rights (option c).
Urban industrial workers, facing challenging working conditions and seeking better labor rights, saw the Republican Party as a proponent of protective tariffs and industrial development. These policies were believed to enhance job opportunities and economic stability for urban workers. Additionally, the Republican Party's association with the abolition of slavery during the Civil War and its commitment to civil rights resonated with African American voters in urban centers, further broadening the party's base.
While the Republican Party did garner support from urban industrial workers, it is crucial to note that political alliances and affiliations were complex during this period, and party platforms evolved over time. The alignment of urban industrial workers with the Republican Party was one facet of the broader political landscape during the late 19th and early 20th centuries, reflecting the diverse interests and concerns of different segments of the American population.
