Can someone summarize the 15 amendment for me please?

The 15th Amendment granted the right of any male citizen of the United States to vote regardless of his race, color or if he was a slave

Explanation:

he right of citizens of the United States to vote shall not be denied or abridged by the United States, or by any State, on account of race, color, or previous condition of servitude.

hello,

answer: a federal government has final authority on interstate/inter provincial  and international affairs, a confederation is one where the central/national government or authority is governing body what does not have final say over the same matters. hopefully this and i will try again if you don't like this answer : )

best of luck!
