From the 1970s to mid-1990s, there was a clear trend across the Western democracies toward the increased recognition and accommodation of diversity through a range of multiculturalism policies (MCPs) and minority rights. These policies were endorsed both at the domestic level in some states and by international organizations, and involved a rejection of earlier ideas of unitary and homogeneous nationhood. Since the mid-1990s, however, we have seen a backlash and retreat from multiculturalism, and a reassertion of ideas of nation building, common values and identity, and unitary citizenship — even a call for the “return of assimilation”.
