Who had the right to vote first women or black men?

The 15th amendment in 1870 gave black men the right to vote first. Women got the right to vote in 1919, a half century later.

Even though former female, white abolitionists had organized and fought diligently alongside black male and black female abolitionists, several famous black male abolitionists abandoned the suffragettes in order to achieve their vote first. This caused a falling out between the two groups. Ultimately, black women, white women, and all women including those who had fought for abolition all had to wait a half century before getting the right to vote. Many black and white female abolitionists died before any woman was given the right to vote which was a disappointment to them for the rest of their lives.

Similarly, black men held office for the first time right after the Civil War while women of all ethnicities' political opportunities, right to have property, and rights to divorce took decades longer to achieve than that of black men. The 14th and 15th amendments deliberately included language that would keep women of any ethnicity from enhanced rights.
