The party was formed in July 2007 from a merger of the
Self-Defence Social Movement () party and several other marginal groups formed by splitters from the Self-Defence of the Republic of Poland. Other parties that participated in the founding of the party were
Self-Defence of the Polish Nation (),
Patriotic Self-Defence, as well regionalist Self-Defence factions of Gorzów and Radom. The main reason behind the creation of Self-Defence Rebirth was to protest the concept of
League and Self-Defence, which would be a merger of Self-Defence with far-right
League of Polish Families. SO also seceded over the promissory notes scandal; the issue of promissory notes () in Self-Defence became notorious in late 2006, when several MPs left the Samoobrona parliamentary club. The party then announced the "launch" of promissory notes against the defectors, which the MPs had signed before the election. This obliged the defectors to pay compensation to the party, which often amounted to several hundred thousand PLN. The faction also focused on rural and agrarian issues, and organized local rural trade unions. This made the faction be considered a
peasant movement, which became popular in the countryside. Conflict between Social Movement and original Samoobrona emerged in early 2006, as electoral lists that the party would register for the
2006 Polish local elections excluded many long-time party activists in favour of new but connected members or independent candidates that the party established cooperation with. Ultimately, Izdebski confronted the leader of the party
Andrzej Lepper, demanding removal of Filipek from the structures of the party. Lepper dismissed the demand and expelled Izdebski from the party, which sparked the exodus of Social Movement faction from the party. Soon, the problem of SRP's electoral lists turned into a scandal, as it was alleged that Lepper promised places on electoral lists and would exclude those who did not have enough money; this turned into a practice of candidates buying positions on the party's list. Izdebski declared that he was one of the victims to the party's electoral list trading, as it was demanded of him to be included in the list only to be excluded when someone paid more for his place. The faction then decided to form a separate political part, gathering 2300 members in total. The party also included
Sławomir Izdebski, a prominent agrarian trade unions activists related to
Polish People's Party and the
peasant movement. In the
parliamentary elections in 2007, Alfred Budner and
Sławomir Izdebski ran for the
Sejm from the
Law and Justice list, but did not obtain a seat as an MP. In
Konin electoral district, Alfred Budner received 6736 votes, and Sławomir Izdebski in
Siedlce electoral district received 3838 votes. In November 2007, another new party that split from Samoobrona was created - the
Party of Regions created out of the regionalist wing of Samoobrona. As Self-Defence Rebirth itself was closely aligned to Samoobrona regionalist, the party postponed their convention in order to start merger talks with the Party of Regions. Following the suicide of Andrzej Lepper in 2011, Self-Defence Rebirth under the leadership of Henryk Dzido sought to revitalise the Samoobrona movement by uniting various minor fractured parties and movements under the single banner of Self-Defence Rebirth. Dzido was considered a conciliatory figure acceptable to all former factions and wings of Samoobrona. After an unsuccessful attempt to take over
Samoobrona following the death of
Andrzej Lepper in 2011, Henryk Dzido decided to relaunch Samoobrona Odrodzenie. An application for party registration was submitted in 2012, and as a result of a court order of 10 January 2013, the party was again listed in the register of political parties. The party tried to re-organize and revive the Samoobrona movement after the death of its leader - in an interview, Henryk Dzido stated that many sympathizers of Samoobrona became active after Lepper's and were interested in making it a political force again. SO stated its belief that while Polish political scene was becoming consolidated between two major parties (right-wing
Law and Justice and centre-right
Civic Platform), this situation would be temporary as "the dominance of two right-wing parties is not normal". In 2011, the party became active in regional farmer councils, with party members such as Stanisław Izdebski becoming members of the Council of the Chamber of Agriculture in Siedlce. However, the planned coalition was cancelled a few days later because the activists of Polish Independence Assembly and the Organisation of the Polish Nation - Polish League withdrew from coalition-talks. As such, the electoral committee "Self-Defence ONP-LP" was annulled. In the second round of the
2015 Polish presidential election, the SO supported
Andrzej Duda of
PiS (against incumbent President
Bronisław Komorowski). In the
2015 Polish parliamentary election, the party did not run. The party extended its cooperation with agrarian trade unions in 2015, organizing the congress of Farmers and Agricultural Organisations at the Warsaw University of Life Sciences. The congress was attended by around 300 farmers, and several road blockades by agrarian activists were subsequently planned and carried out. SO demanded financial compensation to farmers by the government due to declining prices, compensation for crops destroyed by wild boards, as well as speeding up the payment of EU subsidies. Political commentators focused on the emergence of Stanisław Izdebski as a prominent figure within the party, portraying him as "growing into a Lepper". The new organization was founded together with the far-left
Social Justice Movement, and was to be an alternative to centre-left parties such as Democratic Left Alliance and Palikot Movement; it represents the interests of farmers, trade unions, disabled, unemployed and regionalist activists. On 7 October of the same year, the chairman of the grouping, Henryk Dzido, died. The party formulated "The Farmers' Twelve Points" for the 2023 election in cooperation with representatives of agrarian trade unions. The points included long-term loans for farmers, land-leasing, increased investment in animal husbandry research and reduced imports of agricultural products from abroad. Three of main political parties agreed to these demands -
Law and Justice,
Confederation Liberty and Independence and
Polish People's Party. The party spoke particularly warmly of Polish People's Party (PSL), but it refrained from making an endorsement because the coalition partner of PSL,
Poland 2050, rejected the twelve points. Original Samoobrona (SRP) also made no endorsement and asked its supporters to vote with their conscience, although it criticized Law and Justice in its statement, arguing that the party betrayed Lepper and SRP back in 2007. In 2024, Sławomir Izdebski and the party supported the
2024 Polish farmers' protests, and Izdebski's trade union also voted in favour of joining the protests. Izdebski criticized individual farmer groups that signed an agreement with the government, arguing that the agreements signed are worthless and do not take into account most of the problems that forced the farmers to protest in the first place. Izdebski demanded that the EU-imposed restrictions on fur farming be lifted, along with special subsidies to farmers. The demands of Self-Defence Rebirth farmers also included protectionist measures against the Ukrainian grain. ==Ideology==
