Janez Evangelist Krek (1865–1917) evoke with his Westphalian letters that were being published in the Slovene Catholic gazette Slovenec in May and June 1899 in Slovenes interest in their compatriots in Germany. Until then they were in the shadow of the mass emigration to the United States of America. Krek visited them as a Catholic missionary. He associated with them, discussed with German priests the circumstances in comparison to those in Austria. The emigration problematic is only a part of his contemplations; simultaneously he compares religion (Catholic vs. Protestant), political and ideological relations (Catholicism vs. liberalism vs. socialism), economic and social development (Slovene lands vs. Germany) etc. The author analyses in his contribution only Krek’s relation towards Slovene migration situation at the turn into the 20th century, particularly from social-economic aspects and the standpoint to emigration.
