Final answer:
The issues of the Populist movement were adopted by the Progressives, who emerged as a broad-based reform movement that promoted democracy, government and industry efficiency, and social justice, incorporating many Populist ideas.
Step-by-step explanation:
The issues of the Populist movement were adopted by the Progressives. During the late 19th century, the Populist Party, or the People's Party, was formed by farmers and attempted to work with urban workers to challenge the existing political structure and push for reforms.
Many of their ideas became part of the platform of the Progressive Era, as they were taken up by both Republicans and Democrats. Progressivism was characterized by efforts to advance democracy, enhance government and industry efficiency, and promote social justice, which aligned with many goals of the earlier Populist movement.
While the Populists sought to bring together a wide coalition of voters, including the white farmers of the South and the increasingly diverse urban workforce, they struggled to find broad support. The Progressives, on the other hand, emerged as a reform movement with a broad base of support
including a variety of socioeconomic and ethnic backgrounds, and adopted many Populist reforms aimed at addressing issues like the need for government-regulated warehouses and inflation control that would benefit farmers and workers alike.
