Which term established the first schools for african americans in texas

The first school for the African American community - the Paul Laurence Dunbar High School, was opened during the tenure of Ulysses Grant, the then President of the United States of America, in 1870.

This was seen as an act of reformation to empower the black community. However the graduation rates of the school were very less as it hovered at around only sixty percent. They were called coloured schools and were exclusive for the black community.
