The Preamble to the US Constitution speaks of “We the People”—but who counts as “We the People” is a hotly contested question. In Citizenship Under Siege, a project organized by AAC&U and The Democracy Commitment with funding from the National Endowment for the Humanities, seven community colleges used the humanities to explore this topic. Featuring the efforts of project participants and educators engaged in similar work, this issue of Diversity & Democracy illustrates the potential of the humanities to illuminate issues of identity and belonging.
