Ceylon, located in the Indian Ocean, underwent significant changes during the mid-20th century as decolonization movements gained momentum across Asia. The island had been a British crown colony since 1815, and the struggle for independence intensified during World War II, alongside greater political awareness among the residents. In this context, the Ceylon National Congress formed in 1919 and became a crucial player in advocating for self-rule and greater autonomy. The post-war era brought about a series of constitutional reforms, culminating in the passage of the Ceylon Independence Act by the British Parliament in 1947. The formal declaration of independence on February 4, 1948 marked a watershed moment for the island. The ceremony took place in the capital city, Colombo, attended by dignitaries from the British Commonwealth, including the last Governor-General, Henry Monck-Mason Moore. D.S. Senanayake, a prominent leader of the independence movement, was sworn in as the first Prime Minister of the newly sovereign state, instilling hope for self-determination and governance.
