PEPS stands for Protest Events, Photos, and Slogans, and is the name of a novel kind of protest event database. It includes data about the Russian protest wave of 2011-13, which centered on the topic of electoral fraud. As of November 2016, it contains data on 967 protest events from 237 locations, most of them between November 2011 and January 2013, but also including a few election-themed protests from earlier in 2011 and in the period from 2013 to 2016.
PEPS was created by Mischa Gabowitsch at the Einstein Forum in Potsdam/Germany, and is currently maintained by Olga Sveshnikova and Felix Herrmann at the Research Center for East European Studies at Bremen University. Others also participated in data collection at various stages, most notably Manarsha Isaeva (Berlin Social Science Center).
