It prohibits the federal government and each state from denying a citizen the right to vote based on that citizen's "race, color, or previous condition of servitude."
The Fifteenth Amendment (Amendment XV) to the United States Constitution prohibits the federal government and each state from denying a citizen the right to vote based on that citizen's "race, color, or previous condition of servitude."
The Constitution limited the power of government and protect the rights
of citizens by instituting a "balance of power" system in which each of
the three branches of government would be unable to become too powerful
and thus tyrannical.
Hope this helps!!
