In 1762 and 1763, manifestos were issued by Catherine II, and later were extended further by her son Paul I, inviting foreign artisans and others to settle in far-flung rural areas of the Russian Empire in order to help strengthen the economy. Under a policy somewhat similar to the later US Homestead Act, under the manifestos German and other foreign-national settlers and their descendants were offered Russian citizenship, land ownership after three years, religious tolerance (including, in the case of Germans, German clergy and German-language churches), and exemption from the military draft—although by the end of the nineteenth century the last of these had been rescinded. The call was not restricted to Germans, but Germans comprised the largest group to take advantage of it, settling for the most part in Ukraine, Bessarabia, and the mid-Volga region. Those who participated in the migration, known as the Auswanderung, and their descendants are often referred to in English as “Russian Germans” or “Germans from Russia” (rossiiskie nemtsy). A second wave of German immigration occurred in 1894, when some Germans who had settled in Prussia moved across the border into Russia. By 1897, there were over 2 million German immigrants and descendants in the Russian Empire.
