Why were Americans males but not females given the right to vote from the fifteenth amendment?

The Fifteenth Amendment, ratified in 1870, granted African American men the right to vote but did not extend this right to women, regardless of race. This exclusion was largely due to the prevailing societal norms and beliefs of the time, which viewed voting as a male prerogative. Women's suffrage movements were gaining momentum, but they faced significant opposition and were often sidelined in favor of more immediate racial equality issues. It wasn't until the Nineteenth Amendment, ratified in 1920, that women gained the right to vote in the United States.
