The earliest plays were often based on folk themes or had as their aim the strengthening of nationalism. It was not until the late nineteen twenties that a real sophistication began to be achieved, and even then the work depended largely on the work of gifted amateurs working through dramatic societies and the few available theatres. They were handicapped by the lack of a longstanding dramatic tradition such as existed in English, and it has been argued that, with outstanding exceptions, there was little influence at the time from the European classics.
