Self-Defence Social Movement

Self-Defence Social Movement (Polish: Samoobrona Ruch Społeczny, SRS) was a political faction within Self-Defence of the Republic of Poland (Polish: Samoobrona Rzeczpospolitej Polskiej, SRP) and later an independent political party. Social Movement emerged as a political faction within SRP in early 2000s amongst the local activists of the party in Mazowsze. The faction placed particular emphasis on agrarianism and rural interests. It also fought for social justice and defended people against evictions. In 2006, Social Movement entered into conflict with party leader Andrzej Lepper over the party's electoral lists for the 2006 Polish local elections, which included many newcomers and non-members at expense of long-serving members of the party. The conflict came to a head when the leader of the faction Sławomir Izdebski demanded expulsions of Krzysztof Filipek from the party.

Lepper responded by expelling Izdebski from the party instead, prompting Social Movement to break away from SRP and become an independent political party in February 2006. The new party was registered and held its founding convention in March 2006, which took place in Czosnów near Warsaw. The convention was attended by 100 former members of SRP, including those expelled and disaffected with the leadership of the party. The new party then grew to 2300 members, and wanted to challenge SRP in upcoming local elections. However, Lepper filed a lawsuit against the breakaway party, accusing it of being a plagiarism of his party; Social Movement was ruled to be a plagiarized party, which made it unable to participate in the elections. The party dissolved in 2007 and joined Self-Defence Rebirth, a larger Christian socialist SRP breakaway.
