Which idea helped strengthen the acceptance of slavery?

The idea of racial superiority, rooted in pseudo-scientific theories and biblical interpretations, significantly strengthened the acceptance of slavery. Proponents argued that people of African descent were inherently inferior and better suited for servitude, which justified the enslavement of millions. Additionally, economic interests in agriculture, particularly in the Southern United States, fueled the belief that slavery was essential for prosperity and progress. This confluence of ideology and economics entrenched slavery in societal norms and legal frameworks.
