It was first in Helsinki, and then in Vienna at the 9th World Congress of the ITI in June 1961 that President Arvi Kivimaa proposed on behalf of the Finnish Centre of the International Theatre Institute that a World Theatre Day be instituted. The proposal, backed by the Scandinavian centres, was carried with acclamation.
Ever since, each year on the 27th March (date of the opening of the 1962 "Theatre of Nations" season in Paris), World Theatre Day has been celebrated in many and varied ways by ITI National Centres of which there are now almost 100 throughout the world.
Each year a figure outstanding in theatre or a person outstanding in heart and spirit from another field, is invited to share his or her reflections on theatre and international harmony. What is known as the International Message is translated into more than 20 languages, read for tens of thousands of spectators before performances in theatres throughout the world and printed in hundreds of daily newspapers.
