A British commission led by Lord Soulbury reviewed proposals for constitutional reform in Ceylon and recommended a parliamentary system with safeguards for minority representation. Its work set the blueprint for the late-colonial transition to self-government. These recommendations later shaped the constitution used at independence.
Nationwide elections for the House of Representatives were held from August 23 to September 20, 1947. They produced the first legislature of the independence-era system and established the United National Party (UNP) as the main governing force. This parliament would guide the final steps to independence.
On February 4, 1948, Ceylon became an independent dominion within the Commonwealth, with the 1947 constitution coming into force. The new system featured a bicameral parliament (House of Representatives and Senate) and a prime minister and cabinet responsible to the legislature, while a governor-general represented the British monarch. This created a constitutional monarchy with parliamentary government.
The Ceylon Citizenship Act established rules for citizenship soon after independence. In practice, it left many Indian Tamil plantation workers and their families without citizenship, creating a large stateless population. The issue became a long-running political and diplomatic problem for early postcolonial governments.
S. W. R. D. Bandaranaike formed the Sri Lanka Freedom Party (SLFP) on September 2, 1951, after breaking with the UNP. The party promoted a more nationalist and socially reformist platform than the UNP. Its rise helped reshape the two-party competition that dominated early post-independence politics.
On August 12–13, 1953, a nationwide hartal (mass strike and shutdown) protested government austerity measures, including cuts to the rice subsidy. The unrest exposed deep public anger and weakened confidence in the UNP’s post-independence policy direction. It became a major turning point that helped set the stage for the opposition’s gains later in the decade.
Ceylon joined the United Nations on December 14, 1955. UN membership strengthened the country’s international standing and reflected its growing role as a newly independent state. It also signaled a foreign-policy shift toward broader global engagement beyond colonial-era ties.
Parliamentary elections held from April 5 to 10, 1956 brought S. W. R. D. Bandaranaike’s alliance to power, ending an era of UNP dominance. His victory marked a major shift toward Sinhalese-majority cultural nationalism and new state-led reforms. The election reshaped political debate around language, identity, and the meaning of independence.
The Official Language Act (No. 33 of 1956) made Sinhala the country’s sole official language, replacing English. It became a central symbol of the new government’s agenda but also intensified tensions with Tamil-speaking communities. The language policy would strongly influence later protests, negotiations, and political conflict.
On July 26, 1957, Prime Minister Bandaranaike and Tamil leader S. J. V. Chelvanayakam signed an agreement proposing regional councils and limited autonomy measures. It aimed to reduce rising ethnic and language-related tensions through negotiated reforms. Strong opposition from Sinhalese nationalists undermined the pact, and it did not deliver a stable settlement.
Bandaranaike was shot on September 25, 1959 and died the next day, abruptly ending a pivotal reform-minded and nationalist administration. The killing triggered political instability and rapid government changes. It also opened the path for his widow, Sirimavo Bandaranaike, to enter frontline politics.
The March 19, 1960 general election did not give any party a workable majority, making stable government difficult. The result highlighted fragmentation after the 1959 assassination and the limits of short-lived cabinets. Political deadlock led quickly to another election later the same year.
On July 20, 1960, the SLFP won the general election, and Sirimavo Bandaranaike became prime minister on July 21. Her appointment made her the world’s first woman prime minister in the modern era. This marked a major transition in leadership style and consolidated the Bandaranaike family’s political influence.
On October 30, 1964, Prime Minister Sirimavo Bandaranaike and India’s Prime Minister Lal Bahadur Shastri signed an agreement on the status of people of Indian origin in Ceylon. The pact aimed to resolve the long-standing problem created by earlier citizenship laws that left many residents stateless or without clear nationality. It became a major diplomatic step in managing a sensitive post-independence legacy issue.
The March 22, 1965 general election defeated the SLFP-led government and returned the UNP under Dudley Senanayake as prime minister. The outcome reflected voter concerns about governance and shortages, and it showed how coalition-building had become essential to forming governments. This election closed the first major phase of post-independence politics, shaped by language policy conflicts and repeated leadership transitions.
