On 3 December 1981, Nowa Huta became the scene of dramatic events when the communist regime declared Martial Law in Poland. A series of repressions began, aimed at suppressing the growing social discontent. This day, both symbolic and tragic, left an indelible mark on the history of this industrial suburb of Kraków.
Although Martial Law was officially declared at 6 a.m., militia officers raided the homes of Kraków opposition activists during the night of 12–13 December. That one night, 94 people were interned! The residents of Nowa Huta, known for their spirit of solidarity and resistance, did not remain indifferent.
That very same night, the largest opposition strike in the Małopolska region began — approximately 15,000 people went on strike across two shifts! The action started with a strike at the crusher at around 2:30 a.m., and by morning it had spread to all consultation departments of HiL. The Lenin Steelworks, the heart of industrial might, became a witness to workers uniting in defence of shared values.

In those days, the people of Nowa Huta demonstrated not only their opposition to repression, but also their ability to act together in defence of freedom and democracy. 13 December 1981 was written in golden letters in the history of Nowa Huta as a time not only of repression, but also of the heroic resistance of the community. These events, although painful, reveal the strength of human bonds and courage in the face of adversity. Let us therefore remember these moments, to honour the legacy of those who bravely stood up to persecution.
