To revitalize the economy, from 1971 the Gierek regime introduced wide-ranging reforms that involved large-scale foreign borrowing. These actions initially caused improved conditions for consumers, but in a few years the strategy backfired and the economy deteriorated. Another attempt to raise food prices resulted in the June 1976 protests. The Workers' Defence Committee (KOR), established in response to the crackdown that followed, consisted of dissident intellectuals determined to support industrial workers, farmers and students persecuted by the authorities. The opposition circles active in the late 1970s were emboldened by the Helsinki Conference processes.
