We examine diversity ideologies in the United States across four distinct eras: White supremacy/
sanctioned exclusion of racioethnic minorities before the 1960s, the equal opportunity–Civil
Rights era of the 1960s, the diversity management/multiculturalismera of the 1980s and 90s, and
today's inclusion/post-race era. Our examination provides insight into how changes in societal
beliefs and attitudes about non-dominant racioethnic groups and their status and incorporation
into society have influenced the trajectory of diversity practice and research. Based on a content
analysis of HRM articles published on diversity from 2000 to 2011 and demographic trends, we
speculate on the next era of diversity in HRM.
