What nationwide event weakened support for the federal government in the mid-1870s?

The nationwide event that weakened support for the federal government in the mid-1870s was the Panic of 1873, a severe economic depression that led to bank failures, widespread unemployment, and a decline in industrial production. This crisis eroded public confidence in the government's ability to manage the economy and address social issues. Additionally, the ongoing struggles of Reconstruction and the rise of violence and discrimination against African Americans further strained the relationship between citizens and the federal government. As a result, many turned to local or state authorities for solutions, diminishing federal authority and support.
