Who were the journalists and writers that exposed societal problems during the progressive era?

The term "Muckrakers" refers to a specific group of journalists and writers who played a pivotal role during the Progressive Era by investigating and exposing social injustices, corruption, and abuses of power in both government and business. Their work brought attention to issues such as child labor, unsanitary living conditions, and the prevalence of crime and corruption in politics, which sparked public outrage and led to reforms. Notable muckrakers included Upton Sinclair, whose novel "The Jungle" highlighted the appalling conditions in the meatpacking industry, and Jacob Riis, who showcased the harsh realities of life in tenements through his photography and writing.

While reformers, progressives, and activists all contributed to societal change during this time, it was the muckrakers who specialized in investigative journalism that vividly informed the public and influenced legislative reforms, thereby earning them their distinct designation as muckrakers within the context of the Progressive Era.
