The American Civil War (1861-1865) was primarily caused by the disagreement over slavery and states' rights between the Northern states (Union) and the Southern states (Confederate States of America).

The main reasons for the American Civil War can be summarized as follows:

1. Slavery: The Southern states relied heavily on slaves to support their economy, and they saw efforts by the Northern states to abolish slavery as a threat to their way of life.

2. States' Rights: The Southern states believed that they should have the right to decide for themselves whether or not to allow slavery and other issues, rather than being forced to abide by decisions made by the federal government.

3. Economic Differences: There were also economic differences between the Northern and Southern states. The North was becoming more industrialized, while the South remained agrarian, leading to tensions over taxation and trade policies.

The Civil War played a significant role in shaping the later development of the United States. Some of the ways in which it influenced American history include:

1. End of Slavery: One of the most significant outcomes of the Civil War was the abolition of slavery, with the ratification of the 13th Amendment to the Constitution in 1865.

2. Strengthening Federal Power: The Civil War led to a growth in the federal government’s power, as the Union's victory enshrined the supremacy of federal law over state law.

3. Industrialization: The Civil War helped speed up the process of industrialization in the North, as the conflict necessitated the production of weapons, ammunition, and other supplies.

4. Reconstruction: Following the Civil War, a period of Reconstruction began in which the federal government attempted to rebuild the Southern states and ensure the civil and political rights of African Americans.

Overall, the American Civil War was a defining moment in American history that reshaped the nation, put an end to slavery, and ultimately strengthened the power of the federal government.
