ESSA organises annual conferences. They continue a series of conferences which go back to 1992 when the first SimSoc conference was held in Guildford, UK, and to the first international conference on computer simulation and the social sciences (ICSS&SS) held in Cortona, Italy, in 1997. Starting in 2014, this conference series was renamed in "Social Simulation Conference".
The Second ESSA Conference in Social Simulation was held in Valladolid, Spain on 16-19, September 2004.
The first ESSA Conference in Social Simulation was held in Groningen, NL on 18-21 September 2003.
