Institutional racism (also known as structural racism,
state racism or systemic racism) is racial discrimination by governments, corporations, educational institutions or other large organizations with the power to influence the lives of many individuals.
Stokely Carmichael is credited for coining the phrase
institutional racism in the late 1960s. He defined the term as "the collective failure of an organization to provide an appropriate and professional service to people because of their colour, culture or ethnic origin".<sup class="reference" id="cite_ref-4">
