Ken Burn's civil right moive

I learned many things from the Ken Burn's civil rights moive for example the curshulty that the slave famalies went through and the ways they tried to fight aginst it for example Rite Turbman is a women who freed over hunders of slaves through the underground railroads. I also learned that the slave issus divided the senate into two parts the one for slavery and the one aginst slavery. Also that the book Uncle tom's cabine was a very important part of history and also the book Commen sense.
