Sudhindra Sircar, also known as Badal Sarkar, was an influential Indian dramatist and theatre director, most known for his anti-establishment plays during the Naxalite movement in the 1970s and taking theatre out of the proscenium and into public arena, when he transformed his own theatre company, Shatabdi as a third theatre group. He wrote more than fifty plays of which Ebong Indrajit, Basi Khabar, and Saari Raat are well known literary pieces. A pioneering figure in street theatre as well as in experimental and contemporary Bengali theatre with his egalitarian "Third Theatre", he prolifically wrote scripts for his Aanganmanch performances, and remains one of the most translated Indian playwrights. Though his early comedies were popular, it was his angst-ridden Evam Indrajit that became a landmark play in Indian theatre. Today, his rise as a prominent playwright in 1960s is seen as the coming of age of Modern Indian playwriting in Bengali, just as Vijay Tendulkar did it in Marathi, Mohan Rakesh in Hindi, and Girish Karnad in Kannada.

Theatre of India is one of the most ancient forms of theatre and it features a detailed textual, sculptural, and dramatic effects which emerged in mid first millennium BC. Like in the areas of music and dance, the Indian theatre is also defined by the dramatic performance based on the concept of Nritya, which is a Sanskrit word for drama but encompasses dramatic narrative, virtuosic dance, and music. Historically, Indian theatre has exerted influence beyond its borders, reaching ancient China and other countries in the Far East.
