during World War I, most of the Lutosławski family fled to Russia after Poland was occupied by German forces. There, he and his brother Józef organized Polish military forces hoping to liberate Poland with the help of Tsarist Russia. He represented the Central Committee of the PKPS in Moscow in order to help Poles expelled from Congress Poland return to their re-emerging nation. His activities included setting up Polish day care, workshops, hospitals, and centers of assistance and medical care abroad. In 1917, the Russian Revolution broke out. The National Democratic Party, to which Marian and Józef Lutosławski belonged, was strongly opposed to Bolshevik rule. Marian helped evacuate Polish refugees through Murmansk to France and England. He also supported a revolt by Polish forces in Murmansk against the communists. For this, Marian Lutosławski was arrested by the Bolsheviks in Murmansk on 23 April 1918 on suspicion of being a counterrevolutionary. He was taken to Moscow along with his brother Józef, who was arrested two days after him. Marian was executed without trial in a mass execution on 5 September 1918 in Vsekhsvyatskoye, a secluded village outside of Moscow, together with his brother, several days before his trial was supposed to take place. Family His marriage to Maria née Zielinska produced two sons, Franciszek and Zbigniew, and two daughters, Hanna and Zofia. Witold Lutosławski, one of the major European composers of the 20th century, was Lutosławski's nephew. Witold Lutosławski was five years old when his father Józef (born 1882) and Marian were killed.
