Accordnig to some scholars the earliest form of classical theatre of India was the Sanskrit theatre which came into existence after the development of Greek and Roman theatres in the west. One theory describes this development as an offshoot of Alexander the Great's Indian conquest. The invading army staged Greek-style plays and Indians picked up the performance art. While some scholars argue that traditional Indian theatre predated it, there is a recognition that classical Greek theatre has helped transformed it. The Greek origin of Indian theatre has not received popular acceptance.
