What are the three most important developments in African American history from the Civil War Era to Reconstruction?

Three pivotal developments in African American history from the Civil War Era to Reconstruction include the Emancipation Proclamation of 1863, which declared the freedom of enslaved people in Confederate states; the passage of the 13th Amendment in 1865, which formally abolished slavery across the United States; and the establishment of the Freedmen's Bureau, which provided assistance to formerly enslaved individuals and aimed to facilitate their integration into society. These milestones collectively marked a significant shift towards civil rights and laid the groundwork for future struggles for equality.
