World Theatre Day was initiated in 1961 by the International Theatre Institute ITI. It is celebrated annually on the 27th March by ITI Centres and the international theatre community. Various national and international theatre events are organized to mark this occasion. One of the most important of these is the circulation of the World Theatre Day Message through which at the invitation of ITI, a figure of world stature shares his or her reflections on the theme of Theatre and a Culture of Peace. The first World Theatre Day Message was written by Jean Cocteau in 1962.
