Final answer:
Slaves in Massachusetts made their voices heard through various means such as physical attacks on British sentinels, presenting petitions to the legislature, and participating in street demonstrations. They actively engaged in organizing rallies and advocating for their freedom.
Step-by-step explanation:
Blacks attacked lone British sentinels with snowls, clubs, and chunks of ice. This act of defiance and violence allowed slaves to express their discontent and resistance against their oppressors.
Blacks presented five petitions to the Massachusetts legislature in 1773 and 1774. By submitting these petitions, slaves attempted to use the legal system to advocate for their rights and improve their living conditions.
Boston slaves were at the forefront of the black freedom petition movement during the Revolutionary era. They actively participated in organizing demonstrations and rallies to voice their grievances and demand freedom.
