The Polish Institute of Arts and Sciences of America (PIASA) in its eight decades of history frequently collaborated with organizations of other ethnic groups in the U.S., particularly with academic and cultural organizations of East and Central Europe diasporas. Among them strong ties have been established with Ukrainian organizations, especially the Shevchenko Scientific Society and the Ukrainian Academy of Arts and Sciences. The paper describes levels and forms of institutional cooperation. It tries to answer the following questions: was this collaboration accidental or rather resulting from PIASA’s long-term vision and goals? In what fields partners managed to build joint representation?
