Muckraking refers to a style of journalism that seeks to expose corruption, scandals, and social injustices. The term originated in the early 20th century, particularly during the Progressive Era, when journalists investigated and reported on issues like political corruption, corporate greed, and unsafe working conditions. Muckrakers aimed to inform the public and prompt reform through their detailed and often sensationalized stories. Prominent muckrakers included writers like Upton Sinclair, who revealed the unsanitary conditions in the meatpacking industry in his novel The Jungle, and Ida B. Wells, who highlighted the injustices of lynching. Their work played a significant role in raising awareness and influencing public opinion, ultimately leading to legislative changes and social reforms.
