Racism is the belief in the superiority of one race
over another, which often results in discrimination and prejudice towards
people based on their race or ethnicity. Today, the use of the
term "racism" does not easily fall under a single definition.
The ideology underlying racist practices often
includes the idea that humans can be subdivided into distinct groups that are
different due to their social behavior and their innate capacities as well as
the idea that they can be ranked as inferior or superior. The Holocaust is
a classic example of institutionalized racism which led to the death
of millions of people based on race.
