Similarly, religious plays were banned in the Netherlands in 1539, the Papal States in 1547 and in Paris in 1548. The abandonment of these plays destroyed the international theatre that had thereto existed and forced each country to develop its own form of drama. It also allowed dramatists to turn to secular subjects and the reviving interest in Greek and Roman theatre provided them with the perfect opportunity.",  answer the following question.
