The KOR Committee for Social Self-Defense (Polish: Komitet Samoobrony Społecznej KOR) was a Polish civil society group that emerged under the communist rule. It was created in 1977-1978 from the Workers' Defense Committee (Komitet Obrony Robotników). It was one of the movements whose activities led to the creation of Solidarity. The KOR was absorbed into Solidarity in 1981.
The Workers' Defense Committee (Polish: Komitet Obrony Robotników pronounced [kɔmitɛt ɔbrɔnɨ rɔbɔtɲikuf], KOR) was a Polish civil society group that was established to give aid to prisoners and their families after the June 1976 protests and ensuing government crackdown. It was a precursor and inspiration for efforts of the Solidarity trade union a few years later.
It was established in September 1976. A year later it was reorganized into the Committee for Social Self-defence KOR (Komitet Samoobrony Społecznej KOR).
