This question asks about the history of why Howard University in Washington, DC, USA has remained a school whose student and faculty bodies are predominantly African-American.
Do "historically [minority ethnic group]" universities exist in a meaningful sense outside the USA? For example, are there universities in Spain which are historically known for targeting or serving the ethnic Basque community? Are there "Historically Italian" universities in Argentina? Do the Ainu of Japan tend to predominate at a specific Japanese university?
This question is not about whether specialized minority-serving academic institutions should exist, or what their social, political, or economic ramifications are, if any.
This question involves something other than a request to churn and process statistical data - it is a question about social realities and social perceptions in academia. For example, if a census of a particular university in the UK happens to reveal that 65% of the faculty and students are Scottish Highlanders, but there is no significant social perception of the school as a "Highlander School" and no particular adherence to Highlander culture, then it would not count under this question. If, however, there is a UK university whose charter specifically says that it was established "for the education of Highlanders", or which inspires mentions of "oh, that Highlander school!" when mentioned casually in pubs, it counts, even if the actual number of Highlanders on campus as of 2018 is 15%.
