The 1956 law and later constitutional changes in Sri Lanka played a key role in causing friction between the Sinhala and Tamil populations.
- 1956 Sinhala Only Act: This law established Sinhala as the only official language, excluding Tamil, which marginalized the Tamil-speaking people.
- Employment and Education Bias: Tamils faced barriers in government jobs and education due to Sinhala's dominance. This caused Tamil resentment, resulting in protests and unrest.
- Limited Tamil Political Voice: Tamils felt politically excluded, as their calls for equal rights went unanswered, fueling ethnic tensions and conflict.
