Slavery

Today I read The Railroad to Freedom by Vanessa York. I learnt that back in 1880 black people were forced into slavery for the white people. 

If they denied to go work for the white people they were punished.

They were overworked and could get sold when ever and to who ever. 

They were only allowed to get married if their owner said yes

But then that changed they went into protesting and made a underground 

Railway ( a underground network that leads them to freedom at the north of America then to Canada) and they succeeded.
