What measures did the radical republicans take to make reconstruction harder for the white south

The Radical Republicans were the driving force behind several legal changes that allowed African-Americans to gain more rights in American society. This made life for white farmers in the south much more difficult. Here are two examples:

1) 14th amendment- This stated that all individuals born on American soil were citizens. This granted all the rights that white citizens had to African-American citizens.
2) 15th amendment- This gave former slaves and all black men the right to vote. This negatively affected the white south, as the newly freed slave population now had significant political power.

The growth of the empire continued to increase their confidence.
