What amendments to the Constitution radically changed American lives between 1864 and 1872? Be specific as to how they changed American life.

Those were Thirteenth, Fourteenth and Fifteen Amendments. They were also known as Reconstruction Amendments.

Explanation:

First, of the three, Thirteenth Amendment abolished slavery and involuntary servitude with exception to punishment for crime.

The Fourteenth Amendment addresses citizenship rights and equal protection of the laws for all persons. And last but not least Fifteen Amendment spoke about the prohibition of discrimination in voting rights of citizens based on their race, color or previous condition of servitude.

Reconstruction Amendments were the roots of American society as we know it today. They reshaped American society to become one of the freest, most democratic and very multicultural ones in the modern world.
