What organizations started hundreds of anti-slavery churches and helped open schools and colleges for blacks,?

Answer 1

The Quakers, or Society of Friends, was one of the most inclusive churches in the time before the Civil War.

"Although some Quakers held slaves, no religious group was more outspoken against slavery from the seventeenth century until slavery's demise. Quaker petitions on behalf of the emancipation of African Americans flowed into colonial legislatures and later to the United States Congress."

The Methodist Church in the North was, to some extent, sympathetic to the cause of free blacks; the AME Church was founded by free blacks and focused from the start on rights of African Americans.

The American Anti-Slavery Society, started by William Lloyd Garrison in 1833, really came about because of the anti-slavery convictions of many Christians.

During Reconstruction:

"During the years after the war, black and white teachers from the North and South, missionary organizations, churches and schools worked tirelessly to give the emancipated population the opportunity to learn. Former slaves of every age took advantage of the opportunity to become literate. Grandfathers and their grandchildren sat together in classrooms seeking to obtain the tools of freedom."

"A group of Ohioans, including four African American men, established Wilberforce University near Xenia, Ohio, in 1856, and named it after the famous British abolitionist, William Wilberforce. When the school failed to meet its financial obligations, leaders of the African Methodist Episcopal Church purchased it in 1863."
