Under British colonial rule, modern Indian theatre began when a theatre was started in Belgachia. One of the earliest plays composed and staged during this period was Buro Shalikher Ghaare Roa (1860) by Michael Madhusudan Dutt, both in Bengali. Around the same time, Nil Darpan (1858–59, first commercial production in 1872, by Girish Chandra Ghosh at the national theatre in Calcutta) a Bengali play by Dinabandhu Mitra garnered both accolades and controversy for depicting the horror and tragedy of indigo cultivation in rural Bengal, and played a major role in the indigo revolt. Rabindranath Tagore was a pioneering modern playwright who wrote plays noted for their exploration and questioning of nationalism, identity, spiritualism and material greed. His plays are written in Bengali and include "Chitra" ("Chitrangada", 1892), "The King of the Dark Chamber" ("Raja", 1910), "The Post Office" ("Dakghar", 1913), and "Red Oleander" ("Raktakarabi", 1924).
