Ludwik Tadeusz Waryà Âski (24 September 1856 at Martynówka â 2 March 1889 in Shlisselburg) was an activist and theoretician of the socialist movement in Poland.
Waryà Âski was born at Martynówka, Kiev Governorate (ÃÂðÃÂÃÂøýÃÂòúð in present-day Kaniv Raion, Cherkasy Oblast, Ukraine), the son of a January Uprising insurrectionist. In 1865, he began his education at the gymnasium in Bila Tserkva. Beginning in 1874 he studied in Saint Petersburg at the Technological Institute, where he met other socialists, and joined the Polish Socialist Youth. Student disturbances at the Institute in 1875 led to Waryà Âski being forced to leave. He returned to his father's residence under police surveillance, and spent the next year educating himself.
Early in 1877, he arrived in Warsaw and dedicated himself to furthering socialism in Polish. He founded the first socialist magazine in the lands of the Russian-occupied Poland. He then joined the Agronomical School in Puà Âawy while still a leader of Warsaw's workers movement. In 1879 Tsarist police found him in Warsaw and forced him to leave Russia.
He moved to Lvov, and, one year later, to Kraków, where he continued his socialist work. He was arrested by Austro-Hungarian police in February 1879 and jailed until his trial in February 1880, at which he was acquitted (after making a long speech defending the socialist ideas). Nevertheless, he was forced to leave for Switzerland, where his socialist ideas and international contacts developed further. Waryà Âski was the author of the Brussels Program, an ideological declaration of Polish socialists. During his stay in Switzerland, he also met his future wife Anna Sieroszewska (sister of Wacà Âaw Sieroszewski), with whom he had a son, Tadeusz.
In 1882, Waryà Âski returned to Warsaw, where he created the first Polish workers' party, called The Proletariat. In 1883 he was arrested by the Tsarist secret police and, after a trial with 29 co-defendants in 1885, sentenced to 16 years in prison in Shlisselburg. He died there of tuberculosis 4 years later.
During the times of the People's Republic of Poland, the socialist movement pioneered by Waryà Âski was conventionally presented as the starting point of the Polish socialist tradition. Countless Polish schoolchildren memorized Elegia o à Âmierci Ludwika Waryà Âskiego, the powerful poem of Waryà Âski's death by Wà Âadysà Âaw Broniewski.
He was commemorated on the Polish 100 zloty banknote between 1975 and 1996.
In 1952 a Warsaw factory was named after Waryà Âski and became a large producer of excavators, bulldozers, cranes and other building equipment (pl: Warszawskie Zakà Âady Budowy Urzàdzeà  Przemysà Âowych, en: Warsaw Industrial Machinery Construction Works). Today, after privatisation and transformation, it is the core of the Waryà Âski Holding Group.
A 1979 Polish movie Biaà Ây mazur is a biography of Waryà Âski.
There are several monuments to Waryà Âski in Poland and Ukraine.
