What was the biggest disappointment about the reconstruction?

The biggest disappointment of Reconstruction was the failure to achieve lasting racial equality and protect the rights of formerly enslaved people. Despite initial advancements, such as the passage of the 13th, 14th, and 15th Amendments, systemic racism persisted, and discriminatory laws like Jim Crow emerged. Additionally, the withdrawal of federal troops in 1877 led to the resurgence of white supremacy and violence against Black communities, undermining the progress made during Reconstruction. Ultimately, the promises of freedom and equality remained largely unfulfilled for many African Americans.
