How did black families, churches, schools, and other institutions contribute to the development of African-American culture and political activism in this period?

Answer and Explanation:

The question above refers to the period of emancipation, to which blacks were thrown into society without any government plan to help them.

During this period, the black community had a strong family attachment, mainly because they used to be sold in adulthood, losing contact with their families. During emancipation, blacks began a search for their family members, reestablishing their family unit lost during slavery. In addition, blacks began to establish their own churches, being able to return to worship religions and African origin and no longer being forced to submit to the religion of their former owners. Last, but not least, blacks started an educational system that would shelter them and give them the necessary knowledge so that they could be part of the country's economy, politics and social life.
