What did lincoln issue the emancipation proclamation

He stated that all held slaves in the rebel states are and henceforward shall be free

Explanation:

President Abraham Lincoln issued the Emancipation Proclamation, whilst the third year of the bloody civil war was ongoing. The proclamation stated "that all persons held as slaves" within the rebellious states "are, and henceforward shall be free." This allowed the Thirteenth Amendment to come along as well.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
