Summary: Lessons from other historic pandemics show social tension accumulated throughout epidemics lead to significant episodes of rebellion.

If you have not been hearing much of the French Gilets Jaunes or of the Italian Sardines in the last few months, it’s because “the social and psychological unrest arising from the epidemic tends to crowd-out the conflicts of the pre-epidemic period, but, at the same time it constitutes the fertile ground on which global protest may return more aggressively once the epidemic is over,” writes Massimo Morelli, Professor of Political Science at Bocconi, in a paper recently published in Peace Economics, Peace Science and Public Policy.
Professor Morelli and Roberto Censolo (University of Ferrara) argue that we can get an informed opinion about the possible effects of COVID-19 on protest and future social unrest by looking at the great plagues of the past, so they analyze 57 epidemic episodes between the Black Death (1346-1353) and the Spanish Flu (1919-1920). They state that while the epidemic lasts the status quo and incumbent governments tend to consolidate, but warn that a sharp increase in social instability in the aftermath of the epidemic should be expected.
Revolts not evidently connected with the disease are infrequent within an epidemic period, but epidemics can sow other seeds of conflict. Government conspiracy, “the filth of the poor”, foreigners and immigrants have often been singled out as the cause of an epidemic.
“Overall, the historical evidence shows that the epidemics display a potential disarranging effect on civil society along three dimensions,” the authors write.

“First, the policy measures tend to conflict with the interest of people, generating a dangerous friction between society and institutions. Second, to the extent that an epidemic impacts differently on society in terms of mortality and economic welfare, it may exacerbate inequality. Third, the psychological shock can induce irrational narratives on the causes and the spread of the disease, which may result in social or racial discrimination and even xenophobia.”
Focusing on five cholera epidemics, Morelli and Censolo count 39 rebellions in the 10 years preceding an epidemic and 71 rebellions in the 10 years following it.
On the other hand, the authors note that, in the short-term, the necessary restrictions of freedom during an epidemic may be strategically exploited by governments to reinforce power.

Abstract
COVID-19 and the Potential Consequences for Social Stability
Epidemics create risks of social unrest. The great plagues of the past show that social tensions, accumulated over the epidemic and before, often erupted in serious uprisings in the years after the epidemic. Based on historical evidence, we predict that the protests inherited from the pre-COVID-19 period should be crowded out by epidemic-related unrest as long as the epidemic lasts, whereas in the aftermath of the epidemic we should expect the unresolved pre-epidemic grievances to resume even stronger, boosted also by the incremental social grievances related to the epidemic period. While the epidemic lasts, the status quo and incumbent governments tend to consolidate, but a sharp increase in social instability in the aftermath of the epidemic should be expected.
