Which event gave the People's party its most effective political power?

The People's Party, also known as the Populist Party, gained its most effective political power during the 1892 election when it nominated James B. Weaver for president. This election marked the party's first major national performance, where it garnered over a million votes and won several seats in Congress. The party's platform resonated with farmers and laborers disillusioned by economic hardships, significantly influencing American politics in the late 19th century. The subsequent 1896 election further solidified its impact, as it formed a crucial alliance with the Democratic Party, advocating for issues like free silver.
