HBCUs provide a stable and nurturing environment for those most at risk of not entering or completing college: low-income, first-generation college students. Many of these students are academically underprepared for college, yet they're precisely the students that the country most needs to obtain college degrees.
I'm not sure about the Great Britain and Us conflict but I do know that the Mexican American war was the war for the possession of Texas? That may be a contrast you may include. I hope this helps.
