The paper expands upon the role of the Czech national movement and the Czech nation or Czech cultural situation in the Kashubian patrioticdiscourse from the first half of the 19th century until the First World War. It focuses primarily on the period in which it had a direct influence on the „initiation“ of the Kashubian patriotic campaign when the founder of the Kashubian movement, Florian Ceynowa, was studying under Czech professors (J. E. Purkyně, F. L. Čelakovský) in Wroclaw (in the 1840s), as well as on Ceynowa’s subsequent contacts with other members of the Czech national movement until the 1860s. Afterwards, the Kashubian campaign paused in its reflection of the Czech movement. The paper thus then concentrates on the next phase of reflection beginning in the early 20th century, especially in the context of the Young Kashubian program (A. Majkowski, J. Karnowski, K. Kantak). Appreciable ambivalences appear: the Czech movement, and Czechs in general, on the one hand was a paradigmatic example of the successful formation of a modern nation by a formerly non-dominant ethnic group as well as of dynamic social, cultural, and economic development, but on the other hand criticisms of the Czech mentality and Czech political strategies were voiced.
