Many HBCs pre-date the civil right changes and school integration prior to the 1960. Many of them go back to the Civil war and some event pre-dated the war.

There's also HSI, short for Hispanic Serving Institutions. This concept was create in the mid-1960s. Unlike HBCs, institutions could be designated HSI as a result of a federal law. And the law didn't require that these were primarily representing hispanics. Instead the law allowed general institutions to be labeled HSI if they enrolled a certain percentage of latina/latino students along with some additional socio/economic pre-conditions.

As you can see HBCs / HSIs are somewhat different concepts and have a different history. Additionally, in recent years there's been an iflux of hispanic students to HBCs as well.

I hope that other large organizations like Google have more partnerships with HBCs/HSI/Native/Tribal educational organizations. This seams like a start, no real to not cheer it on.

There's no reason to pit groups against one another... it's much better to work together. There's a great datapoint in the history of the VRA (Voting Rights Acts) the people who became enfranchised with the first passing of it fought for expanding the VRA via the 1975 amendment to expand the VRA to other groups including Hispanic/Native/Tribal & Asian minorities. Prior to that states and manipulates in Texas, New Mexico, Arizona, south California were actively working to suppers the Hispanic (such as the Chicanos) vote.

While Hispanics have faced disadvantages and discrimination, they have not faced the kind of outright exclusion that blacks faced for about a century under Jim Crow.

However, there are Hispanic Serving Insitutions: https://en.wikipedia.org/wiki/Hispanic-serving_institution

I also wonder how much you cared about Hispanic schools before you heard about someone helping a Black school. Why the sudden interest?
