How did slavery differ in the northern British colonies compared to the southern colonies before 1750?

In the northern British colonies, slavery was less prevalent and often more integrated into a mixed economy, with enslaved people working alongside free laborers in agriculture, artisan trades, and domestic roles. In contrast, the southern colonies relied heavily on plantation agriculture, particularly for cash crops like tobacco and rice, resulting in a larger enslaved population that was subjected to harsh working conditions and a more rigid slave system. The scale and brutality of slavery in the South created a distinct social hierarchy, whereas the North, with its smaller-scale farms and diverse economies, fostered a different relationship with slavery. Additionally, northern colonies had a growing abolitionist sentiment that began to challenge the institution, which was less pronounced in the South.
