Across the Theravada Buddhist countries of Southeast Asia, the Vessantara Jataka has long been the most famous of the stories (jatakas) of the previous lives of the Buddha. However, little attention has been paid to the jataka's historical vicissitudes. Drawing on comparisons with neighbouring Thailand, this essay suggests there have been significant differences in the jataka's performances and interpretations in Burma (Myanmar), Cambodia and Laos. This essay seeks to historicise understandings of the Vessantara Jataka, showing how social movements, state policies and global pressures have shaped understandings of the jataka differently in each country.
