This article resumes the information gained during the fie ld reserach in the Nova Ves locality in Bosnia in September 2000. We were interested in the Czech community that has lived in this region since 1894. They left Ukraine in order not to have convert to the Orthodox faith. Bosnia, thanks to its religious composition o f the time, offered them religious freedom. The Czech emigrants gained their living mainly from agriculture and trades. From their mother country they brought with themselves m any innovations and cultural traits. This text follows the history of the coming of the Czechs, their old and contemporary customs and usages, thier way of living, habitations, health care, economic conditions, social andfamily life. In the village today lives only a small Czech enclave, composed mainly of old couples or widows. This is being caused by the migration of the youth to the big cities, by the mixed marriaghes and the migration of the Serbs to the village. We were interested to what degree the Czech community had preserved their customs, traditions and usages that were brought to the region more then a hundred years ago by their ancestors, what principies are governing their coexistence with other ethnic groups in the region and the innovations brought to the Czechs by these interetnic contacts.
