his first year in school twice, while his eighth year he was not able to finish. Dzerzhinsky received a school diploma which stated: "Dzerzhinsky Feliks, who is 18 years of age, of Catholic faith, along with a satisfactory attention and satisfactory diligence showed the following successes in sciences, namely: Divine law—"good"; Logic, Latin, Algebra, Geometry, Mathematical geography, Physics, History (of Russia), French—"satisfactory"; Russian and Greek—"unsatisfactory". Political affiliations and arrests Two months before he expected to graduate, the gymnasium expelled Dzerzhinsky for "revolutionary activity" and for posting signs with socialist slogans at the school. He had joined a Marxist group, the Union of Workers (Socjaldemokracja Królestwa Polskiego "SDKP"), in 1895. In late April 1896 he was one of 15 delegates at the first congress of the Lithuanian Social Democratic Party (LSDP). In 1897 he attended the second congress of the LSDP, where it rejected independence in favor of national autonomy. On 18 March 1897 he was sent to Kaunas to take advantage of the arrest of the Polish Socialist Party (PPS) branch. He worked in a book-binding factory and set up an illegal press. As an organizer of a shoemakers' strike, Dzerzhinsky was arrested for "criminal agitation among the Kaunas workers"; the police files from this time state: "Felix Dzerzhinsky, considering his views, convictions and personal character, will be very dangerous in the future, capable of any crime." Dzerzhinsky envisioned merging the LSDP with the Russian Social Democratic Labour Party (RSDLP) and took the same position as influential Social Democrat Rosa Luxemburg on what was referred to in contemporary writings as "The National Question," i.e., the right of nations to self determination. He was arrested on a denunciation for his revolutionary activities for the first time in 1897, after which he served almost a year in the Kaunas prison. In 1898 Dzerzhinsky was exiled for three years to the Vyatka Governorate (city of Nolinsk) where he worked at a local tobacco factory. There Dzerzhinsky was arrested for agitating for revolutionary activities and was sent north to the village of . In August 1899 he returned to Vilnius. Dzerzhinsky subsequently became one of the founders of Social Democracy of the Kingdom of Poland and Lithuania (, SDKPiL) in 1899. In February 1900 he was arrested again and served his time at first in the Alexander Citadel in Warsaw and later at the Siedlce prison. In 1902 Dzerzhinsky was sent deep into Siberia
