The Lacrimosa, dedicated to the trade union leader Lech Wałęsa, was written for the unveiling of a statue at the Gdańsk shipyards to commemorate those killed in the Polish anti-government riots in 1970.  He expanded the work into a requiem, writing other parts to honour different patriotic events over the next four years.  The "Polish Requiem" was first performed in Stuttgart on 28 September 1984.  Penderecki revised and expanded the work in 1993, and expanded it again in 2005 with the additional movement, Ciaccona .  It is called "Polish Requiem" because its parts are dedicated to heroes and victims of Polish history.  One of the better-known works by Penderecki, the mass largely follows the liturgical Latin of the requiem format with the addition of "Święty Boże ", the Polish translation of the Trisagion.
