Answer and Explanation: Fifteenth amendment was passed by congress on February 26, 1886 and was ratified in February 3, 1870. This amendment stated that skin color must not come in the way of right to vote. Every man was allowed to vote whether he was African-American, Chinese or of any color. The main reason of this amendment was to make sure that the right to vote should not be denied on the basis of race or color.
Success:
1) 15th amendment was a success because it took away the racial segregation from voting. People belonging from every color were allowed to exercise their right to vote.
2) It was a symbolic amendment as it was a founding stone for other laws passed in future to avoid segregation on the basis of Race.
Failure:
1) As we talked about the success of 15 amendment, history says that it was originally a failure. So, yes it was because some of the obstacles such as pole taxes and literacy tests were placed in the way of voting because colored people could not afford paying taxes or were not literate to be eligible for voting. So they were technically allowed to vote but actually they were unable to vote because of the obstacles.
2) It is said that it was very much ignored as Federal government was unable to hold the amendment for longer time period which proved that it was not considered because of its weakness.
