Aghast the enormity of human suffering and the sea of blood spilled during the years of World War II, towards its end I decided to compose a monumental work which could help impress on human memory the tragic absurdity of wars.
The ''Requiem'' is dedicated to the victims of human ignorance and, in the first place, to the memory of those who have fallen in every war ever fought of who have suffered in tyrans' prisons.
The style of the ''Requiem'' and the musical means employed are closely related to the universally human character of the work written with a view to appealing to as large a number of listeners as possible [...]. I never tried to search for new, experimental tricks in music, those disputable achievements of the avant-garde that only a narrow audience can really understand.
Roman Maciejewski, Warsaw Autumn 1960

The lyrics are based on a liturgical text
