After the fall of the Polish–Lithuanian Commonwealth in 1795, most of Lithuania was incorporated into the Russian Empire. The beginnings of industrialization and commercial agriculture based on Stolypin's reforms, as well as the abolition of serfdom in 1861, freed the peasants and turned them into migrant-laborers. The pressures of industrialization, Lithuanian press ban, general discontent, suppression of religious freedom and poverty drove numerous Lithuanians, especially after the famine in 1867–1868, to emigrate from the Russian Empire to the United States continuing until the outbreak of the First World War. The emigration continued despite the Tsarist attempts to control the border and prevent such a drastic loss of population. Since Lithuania as a country did not exist at the time, the people who arrived to the U.S. were recorded as either Polish, German or Russian; moreover, due to the language ban in Lithuania and prevalence of Polish language at that time, their Lithuanian names were not transcribed in the same way as they would be today. As a result, information about Lithuanian immigration before 1899 is not available because incoming Lithuanians were not registered as Lithuanians. Only after 1918, when Lithuania established its independence, the immigrants to the U.S. started being recorded as Lithuanians. This first wave of Lithuanian immigrants to the United States ceased when the U.S. Congress passed the Emergency Quota Act in 1921, followed by the Immigration Act of 1924. The Immigration Act of 1924 was aimed at restricting the Eastern Europeans and Southern Europeans who had begun to enter the country in large numbers beginning in the 1890s.
