Lithuanian book smugglers

In the late 19th century, smugglers transported Lithuanian language books printed in the Latin alphabet into Lithuanian-speaking areas of the Russian Empire, defying a ban on such materials in force from 1864 to 1904. Opposing imperial Russian authorities' efforts to replace the traditional Latin orthography with Cyrillic, and transporting printed matter from as far away as the United States to do so, the book smugglers (Lithuanian: knygnešys, or plural knygnešiai, Polish: kolporterzy książek) became a symbol of Lithuanians' resistance to Russification.

After the Polish-Lithuanian insurrection of 1863, the Russian Imperial government intensified its efforts to Russify the Lithuanian population and alienate it from its historic roots, including the Roman Catholic faith, which had become widespread during the years of the Polish-Lithuanian Commonwealth.

During the summer of 1863 Tsar Alexander II issued Temporary Rules for State Junior Schools of the Northwestern Krai, ruling that only Russian-language education would be allowed there. In 1864, the Governor General of the Vilnius Governorate, Mikhail Muravyov, ordered that Lithuanian language primers were to be printed only in the Cyrillic alphabet. Muravyov's successor, Konstantin Kaufman, in 1865 banned all Lithuanian-language use of the Latin alphabet. In 1866, the Tsar issued an oral ban on the printing or importing of printed matter in Lithuanian. Although formally, the order had no legal force, it was executed de facto until 1904. During this time, there were approximately fifty-five printings of Lithuanian books in Cyrillic.
