In May 1981 the burning of the Jaffna library, in the presence of two Sinhalese cabinet members, by what witnesses described as uniformed police and Sinhalese mobs, resulted in the destruction of more than 90,000 books, including palm leaf scrolls of immense historical value. This violent example of ethnic biblioclasm was a major turning point in convincing the Tamil people that the government could not protect them or their cultural heritage and persuaded many of them to back a separate state.
