Final answer:
The Civil War marked both continuity and change from the antebellum period, resulting in a stronger federal government, a transformed economy, and the emancipation of slaves.
Step-by-step explanation:
The Civil War represented a mix of continuity and change from the antebellum period. While there were continuities such as ongoing social reform movements and debates about the institution of slavery, there were also significant changes.
The war resulted in political dominance of the federal government over the states, a shift in economic power from the South's plantation economy to the North's industrial economy, and important social changes, including the emancipation of enslaved blacks and greater tensions between social classes.
The Civil War was a turning point that led to long-lasting transformations in American society, most notably in the structure and powers of governance and the status of African Americans.
