Abstract
Mass emigration of Ukrainians to the United States of America and Canada ran in four main streams – first for the social and economic reasons, then for the political ones. For the entire period of its existence, the local Ukraine community, which identifies profoundly with its roots, has tried to maintain their national traditions.
Particular attention is paid to the third and most important wave of Ukrainian emigration to North America, because it involved the community of Ukrainian politicians, artists, and scientists who found their home in Czechoslovakia in the inter-war period. The contribution introduces the most valuable collections of Ukrainian museums in the USA and Canada and essential social and scientific institutions as well as ethnographic studies of Ukrainian Diaspora.
