It probably because the president was against slavery.
Early farmers who cultivated crops and domesticated animals
Changes: Constitutional end to slavery and granted citizenship and voting rights.
Continuities: Blacks continued to work on plantation lands doing much the same work as before 1865. They were segregated from whites and often were not given the right to vote.
Reformers wanted children to go to school because they would get educated, they would also know their rights, and they could advocate for them in case someone violated them. Children that went to school could get higher paying jobs and even a career. There were lots of advantages!
Have a nice day! :)
