This article presents the main strategies of political action implemented by the social movements OTPOR (Resistance), KMARA (Enough), PORA (It´s time) and KELKEL (Renaissance) during Serbian´s Black Revolution of 2000, Georgia´s Rose Revolution of 2003, Ukraine´s Orange Revolution of 2004 and Kyrguyzstan´s Tulip Revolution of 2005. These strategies, developed under authoritarian and semi-authoritarian regimens, include the establishment of partnerships with various actors of the West, informative campaigns, electoral education, the monitoring of the elections and mobilization against electoral fraud; all of which were developed in a framework of non-violence.
