What group exercised the most influence on the government during late 19 century?

During the late 19th century, corporate interests, particularly large industrialists and business magnates, exercised significant influence on the government. This era, marked by rapid industrialization and the rise of trusts and monopolies, saw these groups lobbying for favorable legislation and policies that benefited their enterprises. Additionally, political machines, which often aligned with business interests, played a crucial role in shaping local and national politics, further entrenching their power. As a result, the government often prioritized the needs of these influential groups over the broader public interest.
