What major change in voting rights was reflected in the Reconstruction Act of 1867?

The correct answer highlights a significant change in the landscape of voting rights during the Reconstruction era. The Reconstruction Act of 1867 aimed to address the political and social consequences of the Civil War, particularly in the Southern states. By mandating that all men, regardless of race, were to be enfranchised, it marked a pivotal moment in American history. This legislation was designed to ensure that formerly enslaved individuals and free black men could participate in the political process, thereby challenging the existing power dynamics that had marginalized them for so long.

This act was part of a broader effort to rebuild the South and reestablish it within the Union, promoting civil rights and equality. It also laid the groundwork for the eventual 15th Amendment, which would formally prohibit denying the right to vote based on race, color, or previous condition of servitude. This significant expansion of voting rights was crucial in advancing the cause of civil rights and representation in the democratic process during Reconstruction.
