how did the 13th amendment affect the relationship between the states & the national government and/or the relationship between the president and congress?

Explanation:

as posted in national geographic. Lincoln and other leaders realized amending the Constitution was the only way to officially end slavery. The 13th Amendment forever abolished slavery as an institution in all U.S. states and territories. In addition to banning slavery, the amendment outlawed the practice of involuntary servitude and peonage

i think the answer is : the declaration of rights and grievances
