What were common beliefs held by many white people?

Many white people historically held beliefs rooted in racial superiority, viewing themselves as inherently superior to other races. This often manifested in support for systemic racism, segregation, and discriminatory practices. Additionally, there was a widespread belief in the idea of manifest destiny and the notion that white civilization was destined to expand and dominate. These beliefs contributed to social, political, and economic inequalities that persist in various forms today.
