What You'll Learn

The US Constitution was signed on September 17, 1787
The Constitution was an attempt to revise the existing government, and it ended up creating a powerful central government. The delegates, wary of centralized power and loyal to their states, crafted compromises to accommodate their widely differing interests and views. The Constitution stands today as one of the longest-lived and most emulated constitutions in the world.
The American Civil War, on the other hand, began on April 12, 1861, when Confederate troops fired on Fort Sumter in South Carolina's Charleston Harbor. This event has traditionally been marked as the start of the Civil War. However, in the Senate, the fall of Fort Sumter was viewed as the culmination of a series of events that led to the war.
The Civil War was a conflict between the Union and the Confederacy, with the latter recognizing the need to counter the Union's naval superiority. The war was among the first to use industrial warfare, with both sides employing railroads, the electrical telegraph, steamships, ironclad warships, and mass-produced weapons. The war resulted in an estimated 698,000 soldiers' deaths and an undetermined number of civilian casualties, making it the deadliest military conflict in American history.

The Civil War began on April 12, 1861
The US Constitution came before the Civil War. The Constitution was signed on September 17, 1787, by 38 delegates, with one delegate signing on behalf of another, bringing the total number of signatures to 39.
The Civil War was a significant conflict in American history, leaving an estimated 698,000 soldiers dead and resulting in an undetermined number of civilian casualties. It was among the first wars to use industrial warfare, with technological innovations such as railroads, the electrical telegraph, steamships, and the ironclad warship playing a pivotal role. The war also witnessed the first use of aerial warfare in the form of reconnaissance balloons.
The war ended with the collapse of the Confederacy and the abolition of slavery, freeing four million enslaved black people. The post-war era, known as the Reconstruction, focused on rebuilding the country, reintegrating the former Confederate states, and granting civil rights to the newly emancipated population.
The Constitution and the Civil War were intricately linked, with the interpretation of the Constitution influencing the arguments of both sides during the war. While slaveholders defended their alleged property rights in slaves, abolitionists emphasised democratic rights related to representation. The war ultimately led to changes in the Constitution, particularly with the addition of the Reconstruction Amendments, which included the Thirteenth, Fourteenth, and Fifteenth Amendments, aimed at abolishing slavery and advancing the civil rights of the freed population.

The US Constitution was amended after the Civil War
The US Constitution was signed on September 17, 1787, and the Civil War took place between April 12, 1861, and 1865. Thus, the US Constitution came first.
Following the Civil War, the US Constitution was amended to include the Thirteenth, Fourteenth, and Fifteenth Amendments, also known as the Reconstruction Amendments. These amendments were proposed and ratified between 1865 and 1870. They were a part of the implementation of the Reconstruction of the American South, which occurred after the Civil War.
The Thirteenth Amendment, proposed in 1864 and ratified in 1865, abolished slavery and involuntary servitude, except as a punishment for a crime. This amendment transformed the United States from a country that was, in Abraham Lincoln's words, "half slave and half free" to one in which the blessings of liberty were extended to all.
The Fourteenth Amendment, proposed in 1866 and ratified in 1868, addresses citizenship rights and equal protection under the law for all persons. It was intended to guarantee the freedom of the formerly enslaved and grant them certain civil rights. The amendment's first section includes several clauses: the Citizenship Clause, the Privileges or Immunities Clause, the Due Process Clause, and the Equal Protection Clause.
The Fifteenth Amendment, proposed in 1869 and ratified in 1870, prohibits discrimination in the voting rights of citizens based on "race, color, or previous condition of servitude." This amendment further solidified the rights and freedoms granted to formerly enslaved people.
These amendments were significant in shaping the post-Civil War United States and ensuring the protection and extension of rights to all citizens, especially those who had been previously enslaved.

The Civil War was an industrial war
The US Constitution came before the Civil War. The former was signed on September 17, 1787, while the latter took place between 1861 and 1865.
The American Civil War, fought between 1861 and 1865, was one of the first instances of industrial warfare. It was fought during the early stages of the industrial revolution, and both sides employed new technologies in their battle strategies. The war was fought not only on the battlefield but also on the home front, with both sides utilising their industrial and economic power to gain an advantage.
The Union, with its more developed industrial economy, was able to increase its military influence and transform many areas of national life, including the industrial, economic, agricultural, mechanical, and financial sectors. The Confederacy, on the other hand, relied heavily on a slave-based agricultural economy and lacked the same level of industrial development. Despite this, they recognised the need to counter the Union's naval superiority and made efforts to build or convert vessels, including ironclads.
Railroads played a significant role in the war, allowing for the rapid deployment of troops and supplies. The telegraph also proved crucial, enabling the quick transmission of messages and information. These technological advancements gave rise to new military strategies and tactics, such as the use of aerial reconnaissance balloons.
The manufacturing capabilities of the North often outshone those of the South, but the Confederacy's wartime manufacturing was crucial to their war effort. Georgia, in particular, became an indispensable site for manufacturing, producing gunpowder, munitions, textiles, and other essential materials. The war also brought about a stimulus for industry, with the number of establishments in Georgia increasing from 1,890 to 3,836 between 1860 and 1870, and the value of yearly products nearly doubling.
The Civil War was a transformative conflict that utilised industrial power to achieve military supremacy. It showcased the importance of industrial and economic might in warfare and demonstrated how technological advancements could be leveraged to gain an advantage on the battlefield.

The US Constitution was amended to abolish slavery
The US Constitution, which was first signed on September 17, 1787, predates the Civil War by almost 80 years. The Civil War began on April 12, 1861, when Confederate troops fired on Fort Sumter in South Carolina.
While the Constitution did not directly address slavery when it was first enacted, it did contain a few provisions that referenced the status of enslaved persons. The Three-Fifths Compromise, for instance, stated that enslaved persons were considered "three-fifths" of a fully free citizen for the purposes of representation in the House of Representatives. Additionally, the Fugitive Slave Clause asserted that a slave remained a slave even if they fled to a non-slavery state.
However, in the years leading up to the Civil War, the issue of slavery became increasingly divisive. Despite efforts by some senators to find a peaceful solution, such as Senator John Crittenden's proposal to extend the Missouri Compromise line, the nation became increasingly polarized.
During the Civil War, President Abraham Lincoln issued the Emancipation Proclamation in 1863, declaring that all persons held as slaves within any state in rebellion against the United States would be "forever free." However, this proclamation did not end slavery nationwide, as it only applied to areas of the Confederacy in rebellion and not to the border states that remained in the Union.
Recognizing the limitations of the Emancipation Proclamation, Lincoln and his cabinet understood that a constitutional amendment was necessary to permanently abolish slavery. In 1864, the Senate passed the 13th Amendment, but it was initially rejected by the House. It wasn't until February 1, 1865, that Lincoln approved the Joint Resolution of Congress submitting the proposed amendment to the state legislatures. On December 6, 1865, the required number of states (27 out of 33) ratified the amendment, officially abolishing slavery in the United States.
The 13th Amendment states, "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction." This amendment, along with the 14th and 15th Amendments, greatly expanded the civil rights of Americans, particularly formerly enslaved people.
