He was born on 5 May 1879 in Kharkiv where he attended secondary school. He studied law at Kharkiv University, but before he had graduated, he was arrested for socialist activities and sent to Saint Petersburg where he spent fourteen months in prison. After his release he was subject to police supervision and prohibited from living in academic cities and thus he could not finish his studies in Russia. It was only in 1904 that he went to Paris and started political and social studies. At that time, his first brochure Po co człowiek żyje [“Why a Man Lives”] was published by the Alliance of Polish Free Thinkers. After his return to Russia, he passed a state examination in law. From 1910, he wrote for the "Russkiye Vedomosti" newspaper. His articles, which were also published in other newspapers, were devoted, among others, to Polish literature. In 1914, he joined the editorial team of the Moscow-based Echo Polskie weekly, which later became a daily. He spent the war years in Russia, actively promoting the Polish cause. In 1918, he was appointed to the Representative Office of the Polish Regency Council, which was soon closed down by the Bolsheviks. In July 1919, Kozłowski was arrested by the Bolsheviks and imprisoned for six months. In January 1920, after his release, he arrived in Warsaw. He worked as editor at the "Tydzień Polski" weekly and then at the "Kurier Poranny" daily. By that time, he had progressed from his youthful fascination with socialist radicalism. Instead, he turned to religion, and as a columnist he attacked the Bolshevik ideology, presenting a description of Soviet reality in a number of articles. He died on 3 September 1927. Among those who appreciated Kozłowski’s journalistic talent and personality was Marian Zdziechowski who wrote an introduction to Kozłowski’s writings published in the Półksiężyc i czerwona gwiazda [“Crescent and the Red Star”] collection. The article presented here comes from this volume.
