The Pennsylvania Slave Trade

Philadelphia, Philadelphia County, Pennsylvania

Marker Inscription

African people, first enslaved by the Dutch and Swedes, survived the brutal voyage from Africa to the Caribbean islands and the Americas, debarking on the Delaware River waterfront as early as 1639. William Penn, other Quakers, and Philadelphia merchants purchased and enslaved Africans. As the institution of slavery increased, these courageous people persevered and performed integral roles in building Pennsylvania and the nation.

The Story

This marker recalls the beginnings of slavery along the Delaware River, where enslaved Africans—first brought by Dutch and Swedish colonists—were landed on the Philadelphia waterfront as early as 1639. Even William Penn and other Quaker founders, later associated with abolition, bought and held enslaved people, and merchants profited from the trade. Despite brutal conditions, these enslaved men and women endured and did essential labor in building Pennsylvania and the young nation.

Why it matters

The marker confronts the uncomfortable truth that slavery took root even in Penn's "holy experiment," honoring the enslaved people whose forced labor helped build the state and the country.

The story behind this marker

AI context

The era

To read this memorial you have to travel back before Pennsylvania was Pennsylvania — to the early 1600s, when the Delaware River valley was a contested colonial frontier. Before the English arrived in force, the Dutch and the Swedes established the first European footholds here, trading and farming along the river.

They did not come alone. The Atlantic slave trade was already binding Africa, the Caribbean, and the Americas into a single brutal system, and enslaved Africans were carried to this waterfront as early as 1639 — survivors of a horrifying ocean passage, landed on the banks of the Delaware to labor in a place not their own.

That date matters. It places slavery at the very beginning of European settlement here, not as a later corruption but as part of the foundation — decades before William Penn ever imagined his colony.

People & events

When Penn founded Pennsylvania as a Quaker "holy experiment" in tolerance and peace, slavery was already present, and the marker refuses to look away from what came next. Penn himself, along with other Quakers and Philadelphia merchants, purchased and enslaved Africans. The founder later associated with liberty of conscience was also a slaveholder.

This is a hard truth, and the memorial states it plainly rather than softening it. It sets Penn and his fellow Quakers — a community that would, in later generations, become deeply identified with abolition — alongside the merchants who profited from human trafficking, and it holds them all in the same frame.

But the memorial's true subject is the enslaved themselves. It honors people whose names it cannot list, who endured the voyage and the bondage that followed, and who — in the marker's own framing — persevered. It insists that their courage and their labor be remembered as part of the story, not erased from it.

Its place in the American story

Americans often tell the story of slavery as a Southern story. This memorial complicates that comfortable geography. Slavery took root in the North too, at the founding of a colony celebrated for its ideals — and enslaved people helped build Pennsylvania and, by extension, the nation.

That tension sits at the heart of the American story: a country that proclaimed liberty while holding people in bondage, a founder who preached conscience while owning human beings. Confronting it honestly is not an attack on the past but an act of fuller memory.

By marking the waterfront where enslaved Africans were first landed, this memorial does something the country long avoided: it names the beginning, honors the people forced to endure it, and credits their labor in building the place we live in now.

If you visit

Come to the waterfront and let the river do some of the work. The Delaware still moves past this spot as it did in 1639, and standing where enslaved people were forced ashore turns an abstract date into a place you can feel underfoot.

This is a memorial, so give it the pace one deserves. Read slowly. Let the plainness of the words settle — the naming of Penn among the enslavers is meant to unsettle, and it should. The site rewards reflection more than a quick photo.

If your Philadelphia trip runs through the landmarks of American liberty, make room for this counterweight. It doesn't cancel that story; it completes it. Leaving here, you'll carry a more honest sense of what the founding cost, and whose forced labor helped make it possible.

Philadelphia, PA · est. 2009

In 1855, an enslaved woman named Jane Johnson and her two sons seized their freedom as their owner brought them through Philadelphia, aided by abolitionists William Still and Passmore Williamson and the Underground Railroad network. Williamson's refusal to produce them landed him in jail, and the resulting trial became a national sensation. The family eventually settled in Boston, free.

Pennsylvania Abolition Society

Philadelphia, PA · est. 1992

In 1775, as revolutionary fervor stirred Philadelphia, reformers founded an organization to defend free Black people who were being unlawfully seized and sold into bondage. Reorganized in 1787 as the Pennsylvania Abolition Society, it broadened its mission to press for education, employment, and opportunity for Black Americans. It became one of the earliest and most influential antislavery bodies in the young nation, counting figures like Benjamin Franklin among its supporters.

London Coffee House

Philadelphia, PA · est. 1991

Opened in 1754, the London Coffee House was a hub of colonial Philadelphia's political and mercantile life, where traders, officials, and townsfolk gathered to talk business and news. But its bustling floor carried a darker function: enslaved Africans, newly arrived by ship, were inspected and sold here at public auction. The site captures the uncomfortable truth that even in the cradle of American liberty, commerce and human bondage stood side by side.
