What is "batiar"

Batiar (also sometimes spelled as baciar), a popular name for a certain class of inhabitants of the formerly Polish city of Lwów. It used to be a part of the city's subculture, Lviv's "knajpa" lifestyle, and became a phenomenon at the beginning of the twentieth century although its roots go back to the mid nineteenth century. It declined after the Soviet occupation of Eastern Poland and its annexation to the Soviet Union as part of the Ukrainian SSR in 1939 and again in 1945. The Soviet authorities expelled most of the Polish inhabitants and suppressed the local Polish culture, although it seems to be recovering at the turn of the 21st century.
