Although American Jews are arguably more assimilated than ever before, Yiddish-and by extension Yiddish culture- is enjoying a bit of a renaissance. Young Jews are increasingly studying the guttural tongue of their ancestors and seeking out live Yiddish entertainment in an attempt to reconnect with their immigrant heritage. While the early-20th century heyday of Yiddish theatre is long gone, there are a handful of companies still working in the form, notably Folksbiene Yiddish Theatre, which has been producing Yiddish shows since 1915. And this year, Brooklyn’s avant-garde Target Margin Theater is also picking up the torch by launching a two-season exploration of the genre, which the producers have the chutzpah to bill as “not your grandpa’s Yiddish theatre.”Yiddish culture has produced a wealth of music, from lullabies to love songs, from mournful songs of loss and exile to the wild dance music of Klezmer. Yiddish literature encompasses all belles letters written in Yiddish, the language of Ashkenazic Jewry which is related to Middle High German. The history of Yiddish, with its roots in central Europe and for centuries in Eastern Europe, is evident in its literature as letters written in Yiddish, the language of Ashkenazic Jewry which is related to Middle High German.
