Globalization implies increases in the frequency and range of interactions among individuals, organizations, societies and cultures across borders. A growing number of such interactions will involve actors from diverse backgrounds and with varying values and differing expectations. Greater frequency, broader range and higher diversity may well invite frictions and tensions, and even bring violent conflicts. To counteract, even prevent, the potential for differences to escalate into disappointment, disengagement or conflict, a set of norms and behaviours well beyond simple acts of courtesy — that is, civility — should govern and guide such interactions, especially across borders. Identifying these norms and behaviours and understanding the meaning and functions of civility as well as the institutions and organizations involved can thus be seen as key tasks for research on globalization. However, ‘civility’, like the term ‘civil society’, with which it shares close linguistic and historical affinity, remains under-researched, as does the link between the two concepts generally.
