What was the significance of the fifteenth amendment? *granted the right to vote to all men (this is the answer)

The 15th Amendment to the United States Constitution was one of the three improvements made to the United States Constitution after the Civil War, it was known also as the Civil War Amendment. The motivation of the 15th Amendment was to guarantee that states or communities were not invalidating men the right to vote, simply,  because of their race.

After the Civil War, America needed to be reconstructed socially an structurally. During the reconstruction of the South, some Sothern states still fond ways to discriminate former slaves, and restrict voting to white men only. These restrictions on voting were revoked by the 15th Amendment, which President Jackson tried to reject with no success. Many states tried to deprive the black voters by creating preferential laws. One of such laws was the "Grandfather Clause", which stated that those who had the benefit or the right to vote prior to 1866 or 1867, or their lineal descendants, would be free from educational, property or tax requisites in order to vote.

As the last of the Civil War Amendments the 15th Amendment permit former slaves to congregate and select people to represent them. This amendment is important as an equitable principle, in deciding who has the right to vote; it acts as a significant event in the correction of the United States Constitution tp guarantee civil rights in general and voting rights, specially for its multiple racial population.
