The correct answer is the major motivation behind the passage of the 13th, 14th, and 15th Amendments is that the Amendments were designed to give male African Americans equal rights of citizenship to white American men. The passage of the 13th, 14th, and 15th amendments was to abolish slavery and establish rights to previous slaves.
The 13th Amendment abolished slavery. The 14th Amendment includes citizen rights and equal protection of the law to everyone. The 15th Amendment did not allowed the states to deny citizens the right to vote, no matter the age, the race or if he was a former slave.
