The founder of the left-wing and Sinhalese nationalist Sri Lanka Freedom Party, his tenure saw the country's first left-wing reforms.   Born to a wealthy, political family, he studied philosophy, politics, and economics at Christ Church, Oxford, and was called to the bar at the Inner Temple. Returning to Ceylon, he entered local politics by joining the Ceylon National Congress. Having been elected to the Colombo Municipal Council in 1926, he was elected from his family seat in Veyangoda to the State Council of Ceylon for two terms between 1931 and 1947, while serving in the second term as Minister of Local Administration in the Board of Ministers. Having founded the Sinhala Maha Sabha in 1936 on Sinhalese nationalist lines advocating for self-rule in Ceylon, he joined D. S. Senanayake by dissolving the Sinhala Maha Sabha and merging it with the United National Party at its formation in 1947. He was elected to the House of Representatives in 1947 representing the United National Party from Attanagalla, which would become the political seat of his family for the next fifty years. Since the Sinhala Maha Sabha formed the largest segment of the United National Party, D. S. Senanayake appointed Bandaranaike as Minister of Health and Local Government and he was elected as the Leader of the House. Following several disagreements, Bandaranaike resigned from the government and crossed the floor to the opposition, forming the Sri Lanka Freedom Party in 1951. Following D. S. Senanayake's sudden death and the elections that followed, Bandaranaike was elected leader of the opposition. Mustering a powerful coalition called the Mahajana Eksath Peramuna and contesting on the lines of Sinhalese nationalism and socialism, he was able to achieve a landslide victory over the United National Party in the general elections in 1956 thereby becoming the fourth Prime Minister of Ceylon.
