Answer: It placed the former Confederate states under federal control
Explanation:
President Andrew Johnson was a democrat who wanted the Southern States of the Confederacy to be readmitted into the United States as soon as possible. He was also against the protection of former enslaved people in those states and showed this in his Reconstruction policies.
Congress which was controlled by the Radical Republicans at the time, did not appreciate Johnson's views and overruled his veto and imposed harsher restrictions on the former confederate states by placing them under federal control and keeping the army in those states so as to ensure the protection of formerly enslaved people.
I can say maybe either trade or language. I lean more on trade because majority of native Americans didn’t speak the same language as the Europeans.
