Final answer:
Enslaved people in the British colonies had the opportunity to gain their freedom if the British had won the American Revolutionary War, as Lord Dunmore offered immediate emancipation to enslaved people who fought for the British.
Step-by-step explanation:
During the American Revolutionary War, enslaved people in the British colonies had the opportunity to gain their freedom by joining the British side. Lord Dunmore, the royal governor of Virginia, offered immediate emancipation to enslaved people who fought for the British.
As a result, thousands of enslaved people ran away to join British forces and fought against their former owners. Between ten and twenty thousand enslaved people gained their freedom as a result of the Revolutionary War.
However, it is important to note that while the British offered freedom, most American revolutionaries continued to uphold slavery and notions of Black inferiority.
