Final answer:
Prince Hall insisted that enslaved people in America were entitled to their natural rights of life, liberty, and the pursuit of happiness, paralleling the principles of the American Revolution and the British constitution.
Step-by-step explanation:
In his petition to the Massachusetts assembly, the free African American Prince Hall insisted that enslaved people in America were entitled to their natural rights, which included life, liberty, and the pursuit of happiness.
Drawing on the ideology of the American Revolution and the principles of the common law, including the 1689 Bill of Rights and the British constitution, Prince Hall argued that the condition of enslaved individuals resembled that of animals rather than human beings, thus violating their natural rights.
Furthermore, he highlighted the contradiction between the ideals that Americans fought for during their struggle against Great Britain and the reality of slavery, advocating for the restoration of freedom as a right inherent to all men.
