Mulattoes were the direct offspring of plantation rapes. Slave masters often threat the female slaves if they resist the masterâs desire of having intercourse. If they fought back, the female slaves will be whipped, will be beaten up, or worse of all, will be killed.

In English, the term is today generally confined to historical contexts. English speakers of mixed white and black ancestry seldom choose to identify themselves as mulatto.
