Answer:
One thing unique was the way that African Americans gathered. During the Antebellum Period, slavery was still prominent (we were still about 30 years from the start of the civil war.) African Americans in the North were able to assemble freely and would publicly speak out against slavery. They could also start schools and churches. In the South, free blacks still lived under the shadow of slavery and found it extremely difficult to meet and hold gatherings with other African Americans. Another unique characteristic is that former slaves would join movements like the Underground Railroad. They would also lead free slaves to safe places and harbor runaway slaves in their homes until a safe place of refuge was found. Some famous slaves who were a part of this movement during the Antebellum period were Harriet Tubman, Frederick Douglass, and Sojourner Truth. These people, and many more aided the movement by writing and publicly speaking out against slavery, (Sojourner Truth's "Ain't I a Woman" Speech.) while others, like Harriet Tubman, were conductors for the underground railroad.
