Power sharing is a technique used in democracies to distribute power between different entities to prevent concentration of power in one place and allow for checks and balances. In Sri Lanka after independence, a series of majoritarian policies established Sinhalese supremacy over Tamils, including making Sinhala the only official language. This caused conflicts and distrust between Sinhalese and Tamil communities, eventually leading to a civil war as Tamil groups demanded an independent state in the north and east of the country.
