Social-media amplification can transform a local incident into multi-city disorder.
Europe’s violent episodes belong on the map.
A closer casebook: what triggered unrest, when smaller groups used violence, where peaceful crowds gathered, and how events evolved.
Why were these episodes missing?
The first atlas version used a small set of causal case studies, not an exhaustive European event register. We have added the previously missing UK, Northern Irish, Irish and French events, with individual source-linked histories.
France in 2026: an unusually confrontational cycle
ACLED measured about 66 demonstrations per day versus a five-year average of 20.5; 24.2% of events in this cycle were classified as riots versus a 1.9% median in earlier cycles. Many small-town events remained peaceful while smaller groups clashed in big cities.
These are specifically France cycle-level shares, not a Europe-wide indicator. Riot classification concerns the event, not every attendee.
