When international slave trade ended how did slave trade continue?

Even after the international slave trade was officially abolished in the early 19th century, slavery continued through domestic slave trades and systems of forced labor. In the United States, for example, the internal slave trade flourished, with enslaved people being sold and transported within the country. Additionally, practices like sharecropping, peonage, and other exploitative labor systems emerged, effectively perpetuating the subjugation and exploitation of African Americans and other marginalized groups. These systems often maintained the economic benefits of slavery while circumventing legal restrictions on the slave trade itself.
