Why is the battle of gettysburg important?

The Battle of Gettysburg, Pennsylvania, is the most important battle of the American Civil War. For three days (July 1-3, 1863) , the army of the South attacked positions held by the North troops along a lengthy front in Gettysburg, but the latter resisted the onslaught. The last and decisive offensive was the famous Pickett's charge, which was painfully unsuccessful and a bloody affair. The Confederation suffered heavy casualties and its forces were rejected by the Union Army. Gettysburg was a major,  strategic defeat. It was a turning point in the conflict. The South lost the strategic initiative. The casualties recorded are the highest of the whole Civil War.

Explanation:

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.
