Kurbas' next major project was Haydamaks (several stagings from 1920 on), a poem on the eighteenth-century Ukrainian upsurge against Polish occupation by Ukrainian poet laureate Taras Shevchenko. The production was the most important Ukrainian theater production of the twentieth century and went on to be staged even after Kurbas' death (without mention of his name, though). Kurbas integrated all the techniques of the Molody era, most notably in his treatment of the choir.
