When did all men get the right to vote?

Why this is the answer

All men got the right to vote with the 15th Amendment, ratified in 1870, which says the vote cannot be denied because of race, color or having been enslaved. It came during Reconstruction, the years right after the Civil War and the end of slavery. Any of the four official answers is accepted: after the Civil War, during Reconstruction, the 15th Amendment, or 1870. Women had to wait another fifty years, until the 19th Amendment in 1920. Memory hook: 15th in 1870 for men of every race, 19th in 1920 for women.
