Karnad found a new approach of drawing historical and mythological sources to tackle contemporary themes and existentialist crisis of modern man through characters locked in psychological and philosophical conflicts. His next was "Tughlaq" (1964), about a rashly idealist 14th-century Sultan of Delhi, Muhammad bin Tughluq, and allegory on the Nehruvian era which started with ambitious idealism and ended up in disillusionment. This established Karnad, now 26 years old, as a promising playwright in the country. It was staged by the National School of Drama Repertory under the direction of Ebrahim Alkazi, with the actor Manohar Singh, playing the visionary king who later becomes disillusioned and turns bitter, amidst the historic Purana Qila in Delhi. It was staged in London by the National School of Drama for the Festival of India in 1982.
