The COVID-19 crisis has fundamentally gendered effects, on intimate partner violence, the division of care labour, healthcare and more. This, and other COVID-19-related changes, may have important consequences for the gendered practice of diplomacy. This essay therefore discusses COVID-19 to highlight the need to pay better attention to gender in the study of diplomacy. For instance, what are the gender dimensions of diplomacy moving online? What are the gendered implications of the increased pressures on consular diplomacy? Turning to longer-term issues, how do gender justice organisations that respond to COVID-19 target diplomats and embassies? How, in turn, do diplomats respond to such advocacy and the underlying problems they address, and does the recent increase in women diplomats make any difference? Gender and diplomacy are intimately interwoven, this essay contends, and understanding the implications of COVID-19 on diplomacy necessitates examining this connection.
