ENThe article deals with the traders of Wystiten and with the border as a modernization factor for Litvaks in transnational space in 19th century. The Litvak Jews at the East Prussian border represented a constitutive factor in the border region. In the 19th century they were able to distinguish themselves within the economic and social space.
