Which colonial region would have experienced a positive impact had the colonies stopped trade with Europe?

The Southern colonies would have experienced a positive impact had they stopped trade with Europe, as they were heavily reliant on agriculture and the export of cash crops like tobacco, rice, and indigo. A focus on local markets could have encouraged self-sufficiency and innovation in farming techniques. Additionally, without European competition, the Southern colonies might have developed stronger domestic trade networks and diversified their economies. Ultimately, a shift away from European dependence could have fostered greater economic resilience in the region.
