Today, Sri Lanka commemorates its 53rd Republic Day, marking over five decades since the nation officially became a Republic on May 22, 1972. This historic transition followed the adoption of a new, locally-drafted Constitution that replaced the British-imposed Soulbury Constitution.
Though Sri Lanka—then known as Ceylon—gained independence on February 4, 1948, it remained a British Dominion. It wasn’t until May 22, 1972 that the country truly gained full sovereignty, officially severing colonial ties and becoming the Democratic Socialist Republic of Sri Lanka.
This day is recognized as a key milestone in the island nation’s history, symbolizing its complete political independence and the beginning of self-determined governance. While Republic Day is commemorated each year, no state-led ceremonies have been held since 2009.
Sri Lanka, with a proud history spanning over 2,500 years, continues to reflect on this momentous occasion as a symbol of national identity, independence, and resilience.
