The American Civil War was fought between the federal government and several southern states that had seceded, with both sides invoking their interpretation of the Constitution to justify their actions. The conflict arose primarily over the issue of slavery and states' rights, with the Southern states seeking to expand slavery into new territories and the North attempting to prevent its spread. The Constitution's ambiguity on slavery, leaving its status in the territories to be decided by Congress, further inflamed tensions, as did the Fugitive Slave Act of 1850, which required Northern states to return runaway slaves to their owners, infringing on their states' rights. Extremists on both sides, slaveholders and abolitionists, drove the country toward war, with each side citing the Constitution to support their cause. The war ultimately led to changes in the Constitution, not through its own amendment processes but as a result of the bloodshed.

The Fugitive Slave Act
The US Constitution, with its compromises and ambiguities, was a key factor in the tensions that led to the Civil War. Both sides of the debate—slaveholders and abolitionists—based their arguments on their interpretation of the Constitution. The so-called "fugitive slave clause", for example, was used by pro-slavery advocates to justify their position, while abolitionists pointed to the absence of the word "slave" in the clause as evidence of its anti-slavery sentiment.
The severity of the 1850 Act led to widespread abuse and backlash, with many free states wanting to disregard it. Some jurisdictions passed personal liberty laws, mandating a jury trial before alleged fugitive slaves could be moved, while others forbade the use of local jails or the assistance of state officials in arresting or returning alleged fugitive slaves. In some cases, juries refused to convict individuals who had been indicted under the Federal law.
The Act also caused controversy in Vermont, where the legislature passed the Habeas Corpus Law in November 1850. This law required Vermont judicial and law enforcement officials to assist captured fugitive slaves but also established a state judicial process, parallel to the federal process, for people accused of being fugitive slaves. This essentially rendered the federal Fugitive Slave Act unenforceable in Vermont and was considered a nullification of federal law, a concept popular among slave states that wanted to nullify other aspects of federal law.

States' rights vs federal power
The American Civil War was fought over the question of whether the federal government or individual states had the right to decide on important issues, such as slavery, tariffs, and taxation. The conflict between states' rights and federal power arose from differing interpretations of the Constitution, specifically the balance of powers between the federal government and individual state governments.
The Constitution, a compromise document, was at the heart of the debate. Both sides could cite the Constitution section by section to support their arguments. For instance, the "`fugitive slave` clause" could be interpreted as either pro-slavery or anti-slavery depending on one's perspective.
Some believed that the federal government had the authority to regulate all aspects of society, while others argued that certain issues should be left solely to the states. This conflict over states' rights versus federal power was particularly pronounced in areas such as tariffs, taxation, and slavery. For example, the Southern states opposed the Tariff of 1828 as it protected Northern industries at their expense, while the North supported it as it raised revenue for the federal government. Similarly, the Fugitive Slave Act of 1850, which required Northern states to return runaway slaves to their owners, was seen by many Northerners as an infringement on their states' rights.
The expansion of slavery into new territories was a significant source of tension between the North and South. As settlers moved west and new territories applied for statehood, the issue of slavery repeatedly arose. The Constitution allowed slavery in the states but left the decision on its status in the territories to Congress. The Southern states, which had grown more dependent on slave labour for agriculture, particularly cotton production, sought to expand their slave-holding territory. In contrast, the Northern states, having abolished slavery, sought to prevent its spread.
The Missouri Compromise of 1820 drew a line across the nation at the 36th parallel, above which slavery would be prohibited and below which it could expand. However, this compromise was later undermined by the Kansas-Nebraska Act, which opened up the territories for settlement but allowed settlers to decide through "popular sovereignty" whether to allow or prohibit slavery. This further inflamed passions in both the North and the South, as both slaveholders and abolitionists flooded into the new territories to influence votes on state constitutions, leading to violent outbreaks in "Bleeding Kansas".

Expansion of slavery
The expansion of slavery into new territories was a significant cause of tension between the North and South, ultimately contributing to the Civil War. The Southern states relied heavily on agriculture, particularly cotton production, which required a large slave labour force. As the nation expanded westward, the issue of slavery in new territories became increasingly contentious. The Southern states, with their dependence on slave labour, sought to expand their slave-holding territories to meet the growing demand for cotton. In contrast, the Northern states, having abolished slavery, aimed to prevent its spread.
The Missouri Compromise of 1820 attempted to address this issue by drawing a line at the 36th parallel, above which slavery would be prohibited and below which it could expand. However, this compromise was later undermined by the Kansas-Nebraska Act, which allowed settlers in the new territories to decide through "popular sovereignty" whether to allow or prohibit slavery. This led to a rush of both slaveholders and abolitionists into the territories, resulting in violent clashes and further inflaming passions on both sides.
The Southern states' desire to expand slavery was driven by economic and political factors. Agriculture, especially cotton production, was the backbone of the Southern economy, and slave labour was seen as essential to maintaining their way of life. Additionally, the Southern states held fewer seats in Congress, creating a power imbalance that further fuelled their determination to protect and expand slavery. Many Southerners viewed the expansion of slavery as a matter of states' rights and individual freedom, believing that the federal government had no authority to regulate slavery in their territories.
On the other hand, the Northern states had a more diversified economy and strong beliefs in freedom and democracy, which clashed with the institution of slavery. They feared that the expansion of slavery would eventually lead to the enslavement of all black people, not just those in the South. The tension between states' rights and federal power was a significant factor in the lead-up to the Civil War, with the North and South holding opposing views on the role of the federal government in regulating slavery. Ultimately, the conflict over the expansion of slavery, combined with other economic and political differences, pushed the nation towards secession and civil war.

Property rights vs democratic rights
The American Civil War was fought between the North and the South, with both sides citing the Constitution to justify their respective positions on slavery. The Constitution's "fugitive slave" clause, for instance, could be interpreted as either pro-slavery or anti-slavery, depending on one's perspective.
At the heart of the conflict was the tension between property rights and democratic rights. Slaveholders argued that they had property rights over slaves, while abolitionists emphasised democratic rights related to representation and equality. This divide was so profound that it led to extremists on both sides, driving the country towards war. The abolitionists' co-opting of the Republican Party and their demand for the end of slavery threatened the economic foundation of the South, where slavery was a cornerstone of the social and economic system.
The property rights argument centred on the notion that slaves were considered legal property, akin to any other form of tangible property, such as land or goods. This perspective was deeply entrenched in the Southern states, where the institution of slavery was a significant part of the cultural, social, and economic fabric. Slaveholders believed that their right to own and utilise slave labour was protected by the Constitution, which they interpreted as safeguarding private property rights.
In contrast, abolitionists championed democratic rights, primarily the inherent right of all individuals to liberty and equality. They argued that the Constitution, with its emphasis on freedom and democracy, inherently conflicted with the institution of slavery. The abolitionists' interpretation of the Constitution emphasised the democratic ideals of representation and the fundamental equality of all people, regardless of race. They contended that slavery was a violation of the natural rights guaranteed by the Constitution, such as life, liberty, and the pursuit of happiness.
The tension between property rights and democratic rights was a fundamental aspect of the ideological divide between the North and the South. The Constitution, with its compromises and ambiguous clauses, provided ammunition for both sides, contributing to the intensification of the conflict. Ultimately, the Civil War led to a transformation of the Constitution, as the institution of slavery was abolished and the rights of formerly enslaved individuals were recognised, demonstrating the power of constitutional interpretation and its impact on societal change.

Extremists on both sides
For slaveholders, the Constitution's alleged property rights in slaves were paramount. They argued that the Constitution allowed slavery to exist in the states and that it was up to each state to decide its legality. The Southern states relied heavily on agriculture, particularly cotton production, which required a large number of slaves. They sought to expand their slave-holding territories to meet the increasing demand for cotton, asserting their rights to transport their way of life into new territories.
On the other hand, abolitionists emphasised democratic rights related to representation. They opposed the expansion of slavery as it conflicted with their beliefs about freedom and democracy. The Northern states, having abolished slavery, aimed to prevent its spread to new territories. They also believed that the expansion of slavery would eventually lead to the enslavement of all Black people, not just those in the South.
The Fugitive Slave Act of 1850, which required Northern states to return runaway slaves to their owners, was seen by Northerners as an infringement of their states' rights. Similarly, the Nullification Crisis in the 1830s highlighted the conflict between states' rights and federal power. South Carolina declared its right to nullify federal laws that conflicted with its state laws, while President Andrew Jackson threatened to use force to enforce federal law.
The Missouri Compromise of 1820, which drew a line prohibiting slavery above the 36th parallel, was intended to settle disputes between the North and South. However, the subsequent Kansas-Nebraska Act undermined this compromise by opening up the territories for settlement and allowing settlers to decide on the status of slavery through "popular sovereignty". This further inflamed passions on both sides, with both slaveholders and abolitionists flooding into new territories to influence votes on state constitutions, leading to violent clashes in "Bleeding Kansas".
