Doc 1. 1917 was a time during war. The US did enter during this time, and also the Industrial revolution was still going. With tenements going up everywhere and factories producing needed products. Many families were poor at the time of this. There were workers needed. And who else than the relatively recently freed blacks (Pardon) as cheap labor for factories. Besides, the south had an unbelievable amount of racism still. The journey up north should've been very freeing.
Doc 2. Remember this was a time when there was still racism. Jim crow laws. The KKK (Klu Klux Klan) black people wanted out and now. There were lynchings. Set massacres. To find work elsewhere other than the literal (Pardon my french) hellhole in the south. To go up north was like heading to the promised land.
Hope this helps. (Now my head hurts from reading, Jk.)
In order for the constitution to be amended it must be passed by the federal government and it also has to be passed by 3/4 of the states... the whole point of federalism is that in addition to a central government (the united states federal government) there are separate sovereign states or provinces (individual states)
because an amendment needs the blessing of both the federal government and the states it demonstrates federalism
