Reasons for the Thirteenth Amendment (Edexcel A-Level History): Revision Notes
Reasons for the Thirteenth Amendment
Context: The Civil War and emancipation
The Civil War (1861-65) stands as the most devastating conflict in American history. This brutal struggle claimed 620,000 American lives and left the Confederate economy in ruins. Under President Abraham Lincoln's leadership, the northern states emerged victorious, achieving two crucial goals: reuniting the fractured nation and liberating four million enslaved black Americans.
Lincoln had taken a decisive step towards ending slavery on 23 September 1862 by issuing the Emancipation Proclamation. This groundbreaking declaration stated that from 1 January 1863 onwards, any enslaved person in territory under Confederate control would be permanently free. This marked a fundamental shift in the war's purpose, transforming it from merely a struggle to preserve the Union into a war for human freedom.
The Civil War remains the deadliest conflict in American history, with casualties exceeding the combined American deaths in World War I, World War II, and the Vietnam War. The scale of destruction, particularly in the South, would shape American society and politics for generations to come.
Controversies and limitations of the Emancipation Proclamation
Despite its significance, the Emancipation Proclamation sparked considerable debate and faced important limitations that revealed the need for more comprehensive action.
Many questioned Lincoln's true motivations. Was this proclamation merely a tactical weapon designed to weaken the Confederacy and secure military victory? Critics pointed to significant gaps in the proclamation's coverage. Notably, it made no reference to enslaved people in areas already under northern control by 1 January 1863 - which comprised approximately one-third of the former Confederacy. Additionally, the proclamation excluded loyal border states such as Missouri, Kentucky, Maryland and Delaware, where slavery continued to exist despite these states remaining in the Union.
Critical Limitation: The Emancipation Proclamation did NOT free all enslaved people. It only applied to Confederate-controlled territories and excluded border states that remained loyal to the Union. This meant that roughly one-third of enslaved Americans were not covered by the proclamation.
The political landscape proved challenging as well. The main opposition party, the Democrat Party, refused to support the proclamation and actually gained seats in the November 1862 congressional elections, demonstrating that Lincoln lacked universal support for his anti-slavery measures.
These limitations highlighted a crucial problem: the Emancipation Proclamation was essentially a wartime measure. What would happen to slavery once the war ended? Would it creep back into existence? Lincoln recognised that a more permanent, legally binding solution was essential.
Lincoln's commitment to ending slavery permanently
Despite the controversies, substantial evidence demonstrates Lincoln's genuine commitment to abolishing slavery completely. Before the Civil War even began, Lincoln had made clear public statements asserting that the United States could not survive as a united nation unless the slavery question was resolved. He viewed slavery as a fundamental contradiction to American principles that would eventually tear the country apart.
From 1863 onwards, the abolition of slavery became an official northern war aim, not merely a military tactic. However, Lincoln understood that winning the war would not automatically secure slavery's permanent end. He needed to act decisively whilst he still had the political momentum and before the conflict officially concluded.
Lincoln's view that America could not endure "half slave and half free" echoed his famous 1858 "House Divided" speech, where he argued that the nation would eventually become all one thing or all the other. This long-held conviction drove his determination to resolve the slavery question permanently.
Lincoln's re-election in November 1864 proved crucial. He interpreted this victory as a clear mandate from the American people to end slavery forever. The president believed such a momentous change required more than just his presidential authority - it needed to be embedded in the nation's fundamental law through a constitutional amendment.
The political strategy behind the Thirteenth Amendment
Lincoln demonstrated shrewd political judgment in his approach to achieving permanent abolition. He recognised that ending slavery was too significant an issue to be seen as merely a Republican Party achievement. To ensure lasting legitimacy and national acceptance, the measure needed bipartisan support from both his own Republican Party and the opposition Democrats.
Strategic Decision: Lincoln chose to seek approval from the existing Democrat-influenced Congress rather than waiting for the new Republican-dominated Congress in March 1865. While this made passage more difficult, it ensured the amendment would be seen as a truly national decision, not just a partisan victory.
Facing a practical challenge, Lincoln made a calculated decision about timing. Rather than waiting until March 1865, when a new Republican-dominated Congress would be convened (making passage easier but potentially less legitimate), he chose to submit his proposal to the existing Congress, which contained a substantial number of Democrat members. This was a risky strategy that required genuine persuasion and compromise.
The passage of the Thirteenth Amendment
Lincoln's political skills were put to the test as he worked to secure the necessary votes. Through personal persuasion and political negotiation, he managed to convince sufficient Democrat congressmen to join with Republican members in supporting the Thirteenth Amendment, which would make slavery illegal throughout the United States forever.
On 31 January 1865, a momentous vote took place in the House of Representatives. The proposed amendment passed by the narrowest of margins - just two votes beyond the required two-thirds majority, with a final tally of 119 votes in favour to 56 against. This slim margin revealed how controversial and hard-fought this achievement truly was.
The narrow margin of victory - just two votes more than the two-thirds majority required - meant that Lincoln had to work tirelessly to persuade individual Democrat congressmen. Every single vote counted, and the outcome remained uncertain until the final tally was announced. The closeness of this vote demonstrates how divided the nation still was on this fundamental issue.
However, passing Congress was only the first step. For an amendment to become officially part of the US Constitution, it also required ratification by three-quarters of the states. By December 1865, sufficient states had given their approval, and the Thirteenth Amendment became constitutional law.
The timing proved significant. The Civil War came to an end in April 1865 when Confederate general Robert E. Lee surrendered his army at Appomattox Court House, Virginia. Lincoln had successfully achieved his goal of securing slavery's permanent abolition before the war's official conclusion, ensuring that there could be no legal basis for slavery's return during the peace negotiations and reconstruction that would follow.
At the annual meeting of the American Anti-Slavery Society (the leading abolitionist movement), William Lloyd Garrison, one of its most prominent members, declared that his life's work as an abolitionist had been completed - the Thirteenth Amendment had achieved what generations of campaigners had fought for.
Exam focus: Why the Thirteenth Amendment was necessary
When answering exam questions about the reasons for the Thirteenth Amendment, consider these key points that demonstrate both the practical limitations of the Emancipation Proclamation and the strategic thinking behind seeking a constitutional solution.
Key Points to Remember:
Political reasons:
- The Emancipation Proclamation had limited legal standing as a wartime measure
- A constitutional amendment would make abolition permanent and unchallengeable
- Bipartisan support would give the measure greater legitimacy across the nation
- Lincoln's re-election provided a democratic mandate for action
Practical reasons:
- The proclamation didn't cover all enslaved people (border states, Union-controlled areas)
- There was uncertainty about slavery's status once the war ended
- Four million enslaved people needed clear legal freedom
- The nation needed to resolve the contradiction between slavery and its founding principles
Strategic timing:
- Lincoln wanted to secure abolition before the war ended
- He chose to work with a Democrat-influenced Congress to show national unity
- Acting quickly prevented any possibility of slavery being reinstated in peace negotiations
Remember!
- The Emancipation Proclamation (23 September 1862, effective 1 January 1863) freed slaves in Confederate-controlled territory but had significant limitations
- Lincoln viewed his November 1864 re-election as a mandate to end slavery permanently through constitutional change
- The Thirteenth Amendment passed Congress on 31 January 1865 by just two votes (119-56), requiring Lincoln to secure Democrat support
- The amendment was ratified by three-quarters of states by December 1865, making slavery illegal throughout the USA
- Lincoln strategically secured the amendment's passage before the Civil War ended (April 1865), ensuring slavery could not return during reconstruction
