DESCRIPTION:How does the nature of social media content shape the diffusion
  of protest? This paper provides causal evidence from the 2023 Nahel riots 
 in France\, a nationwide wave of unrest triggered by a police killing and p
 ropelled by online mobilization. Using data on 537 protest events and more 
 than 50\,000 geolocated Instagram interactions\, we construct a municipalit
 y-by-day panel of social media exposure. Our identification strategy levera
 ges exogenous variation in pre-riot Instagram connectivity—measured via r
 esidualized comment flows on a network seeded on football celebrities’ po
 sts—to isolate the diffusion of protest through online ties. We find that
  digital exposure to protest in connected municipalities significantly incr
 eases the probability of local protest\, with effects concentrated the foll
 owing day. Beyond volume\, we show that protest diffusion is content-depend
 ent. Pro-movement\, emotionally salient\, and visually prominent posts are 
 particularly effective at promoting both online engagement and offline acti
 on\, while exposure to fear-inducing or repressive imagery discourages prot
 est despite increasing attention. Posts with coordination cues (explicit ca
 lls to action or protest logistics) have the strongest mobilizing effects. 
 Our findings show that image-based social media accelerate protest diffusio
 n not only by lowering coordination barriers but also by amplifying emotion
 al cues. They reveal how emotional tone\, political alignment\, and visual 
 structure jointly condition the spread of digital protest.\\n\\nContact: SÃ
