William Thornton, depicted in this watercolor miniature, embodies the very complex relationship many had with slavery. Although born on his family’s sugar plantation on Tortola, British Virgin Islands, Thornton was raised by Quakers in England, developing antislavery sentiments while embracing Enlightenment ideals of freedom and equality. Despite being trained as a doctor, he went on to become a prominent architect in early Washington, D.C., serving as the first architect of the Capitol and as a city commissioner. Thornton called slavery the “darkest stain” on society yet benefitted from enslaved labor in his household and on construction projects in Washington, D.C.
Driven to find an end to the practice of slavery, Thornton became an outspoken supporter of emancipation and subsequently, colonization. In 1791, Thornton introduced a petition to lead a colony of newly-free Black men to Sierra Leone and later proposed Puerto Rico as a possible location for such a settlement. At its core, colonization supported the idea that Black and White Americans could not live in harmony, and that instead, African Americans should “return” to Africa or elsewhere.
Abolitionists were divided on the issue of colonization. Ultimately, colonization efforts failed, as many Black Americans desired to remain in their home country, rather than being driven away. William Thornton and others promoted colonization as a solution to slavery, when it was instead a diversion from the realities of integrating American society.
