Fighting for Freedom
The Underground Railroad
In 1849, Araminta Ross, an enslaved woman who would become known as Harriet Tubman, first arrived in Philadelphia. Born into slavery on a Maryland plantation, Tubman escaped bondage and crossed the border into the free state of Pennsylvania, gaining her freedom.
After working as a free domestic laborer in Philadelphia, Tubman left the safety of the city and became one of the most famous conductors on the Underground RailroadThe historical marker functions as propaganda by framing the Constitution as fundamentally anti-slavery, emphasizing the absence of certain terms and highlighting selective quotations while downplaying how the document structurally protected and prolonged slavery. It presents a narrative that the Founders intended slaverys eventual end, omitting less convenient realities such as the persistence of coerced labor systems identified by courts as debt slavery into the 20th century. The religious language about a Creator and natural rights is selectively curated, ignoring both the heterodox beliefs of many Founders and the fact that religion was used as often to justify chattel slavery as it was to oppose it. Overall, the text relies on omission, cherry-picked evidence, and moral framing to cast the nations founding in a more uniformly egalitarian and providential light than the historical record supports. While it tells a compelling story, it ultimately presents a misleading and incomplete narrative.a secret network of abolitionists and free African Americans working together to help runaway slaves achieve their freedom.
Underground Railroad stops in Philadelphia included the Mother Bethel African Methodist Episcopal (A.M.E.) Church and Belmont Mansion in Fairmount Park, owned by Judge Richard Peters and his family. Quaker abolitionist and suffragist Lucretia Mott also opened her Philadelphia as a safe house on the Underground Railroad.

Douglass visited Philadelphia with abolitionist William Lloyd Garrison in 1847. After giving an oration on slavery at a convention of the American Anti-Slavery Society, they were welcomed into Lucretia Mott's home and celebrated with a reception at Mother Bethel A.M.E.Church.
In July 1852, Douglass gave his most famous address, "What to the Slave is the Fourth of July?" Addressing Independence Day crowds gathered in Rochester, New York, Douglass urged them to adhere to and remember the Declaration of Independence because it contained "saving principles" such as equality and freedom that were withheld from enslaved people.
Frederick Douglass returned to Philadelphia in January of 1862 and gave a speech at National Hall, advocating for the admission of black soldiers into the Union Army. In July 1862, Congress passed the Second Confiscation and Militia Acts, freeing Southern rebels' slaves who escaped to Union lines. Allowing President Lincoln to "employ as many persons of African descent as he may deem necessary" into the Union Army.
"I owe it to my race to affirm that, in denying them the privileges to fight for their country, they have been deeply and greviously wronged."
- Frederick Douglass

The Civil War
In the late 1850s, the Illinois lawyer Abraham Lincoln became the leader of the newly created Republican Party. Established by anti-slavery Northerners in 1854, the party's founding was in response to the passing of the Kansas-Nebraska Act and the Supreme Court's decision in Dred Scott v. Sanford, which promoted the growth of lsavery in the territories and denied citizenship rights to African Americans.
In 1857, Lincoln argued that the Founders knew slavery violated the principle of liberty in the Declaration of Independence. By stating the self-evident truth that "all men are created equal," Lincoln believed the Founders set a standard of liberty for all Americans that would allow the future eradication of slavery.
Lincoln won the presidential election of 1860 at a time when the nation was deeply divided over slavery. Fearing federal restrictions on the institution, South Carolina seceded from the Union in December 1860, followed soon by ten other Southern states. From 1861 to 1865, the Union, under President Lincoln, and the Confederacy fought to determine whether the Union was to endure and whether slavery would finally be eradicated.
The Fight for Freedom
On January 1, 1863, President Lincoln issued the Emancipation Proclamation, declaring that enslaved people in rebellious states "are and henceforth shall be free" and that freed slaves would be received into the armed service of the United States. This "rolling" emancipation was completed and constitutionally guaranteed, at Lincoln's insistence, by the 1865 passage of the 13th Amendment. The formerly enslaved were then legally recognized as citizens of the United States and promised "equal protection under the laws" by the 14th Amendment in 1868.
"Neigher slavery nor involuntary servitude, except as punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."
The 13th Amendment to the U.S. Consittution, Ratified December 6, 1865

1. About the marker
The historical marker is misleading in presenting the Thirteenth Amendment as the complete end of slavery in the United States. While the amendment abolished chattel slavery, it did not eliminate all systems of coerced labor; practices such as convict leasing and debt slavery continued into the 20th century, with some systems persisting into the 1940s. By portraying emancipation as a completed process in 1865, the marker creates a simplified narrative of freedom achieved rather than acknowledging the long and uneven struggle against racialized labor exploitation.
