A Romanian episcopate established for serving the United States was established in Detroit in 1929. In 1937 this episcopate, headed by Bishop Policarp Morusca, established a cultural center in Grass Lake. John Radzilowski, the author of an entry on Romanians in The American Midwest: An Interpretive Encyclopedia, wrote that this center "remains the most significant Romanian cultural institution" in the United States.
