Final answer:
Abolitionists and slaves resisted the Fugitive Slave Act by aiding escaped slaves, promoting civil disobedience, and forming the Underground Railroad. They engaged in non-violent acts like courthouse confrontations and enacted laws to hinder federal actions but did not primarily resort to violent uprisings.
Step-by-step explanation:
Abolitionists and slaves resisted the Fugitive Slave Act primarily through aiding escaped slaves and promoting civil disobedience. In northern communities, both blacks and whites united to protect runaways, forming vigilance committees and enacting 'personal liberty laws' to limit the assistance federal officials could receive at a state level. The Underground Railroad was a critical network in this resistance, with figures such as Harriet Tubman playing pivotal roles in assisting slaves to freedom, despite the risks of punishment under the law.
In addition to these acts of defiance, sometimes resistance took on a more direct form. Abolitionists orchestrated public demonstrations and courthouse confrontations to protect individuals like Anthony Burns. While some advocated for violent means to oppose the Fugitive Slave Act, most of the resistance activities were non-violent, focusing on evasion, legal challenges, and public advocacy against slave power.
