Rising Sinhalese nationalist sentiment in Ceylon, partly fuelled by the Official Language Act debates of 1956, created communal tensions between the Sinhalese majority and Tamil minority. This atmosphere of ethnic rivalry set the conditions for organised violence against Tamil communities.
Beginning with anti-Tamil rioting in Colombo and counter-rioting in Batticaloa, the worst violence unfolded in the Gal Oya valley, where Sinhalese colonists and Gal Oya Development Board employees used commandeered government vehicles, dynamite, and weapons to massacre Tamil minorities. Over 150 people died before police and army restored order.
The pogrom marked a turning point in Sinhalese-Tamil relations, establishing a pattern of ethnic violence in Ceylon and deepening Tamil distrust of the state. It is widely regarded as a precursor to the prolonged civil conflict that would eventually engulf Sri Lanka in subsequent decades.
