Post-independence era
The Barrow government sought to diversify the economy away from agriculture, seeking to boost industry and the tourism sector. Barbados was also at the forefront of regional integration efforts, spearheading the creation of CARIFTA and CARICOM. The DLP lost the 1976 Barbadian general election to the BLP under Tom Adams. Adams adopted a more conservative and strongly pro-Western stance, allowing the Americans to use Barbados as the launchpad for their invasion of Grenada in 1983. Adams died in office in 1985 and was replaced by Harold Bernard St. John; however, St. John lost the 1986 Barbadian general election, which saw the return of the DLP under Errol Barrow, who had been highly critical of the US intervention in Grenada. Barrow, too, died in office, and was replaced by Lloyd Erskine Sandiford, who remained Prime Minister until 1994.
Owen Arthur of the BLP won the 1994 Barbadian general election, remaining prime minister until 2008. Arthur was a strong advocate of republicanism, though a planned referendum to replace Queen Elizabeth as Head of State in 2008 never took place. The DLP won the 2008 Barbadian general election, but the new Prime Minister David Thompson died in 2010 and was replaced by Freundel Stuart. The BLP returned to power in 2018 under Mia Mottley, who became Barbados's first female prime minister.
The Government of Barbados announced on 15 September 2020 that it intended to become a republic by 30 November 2021, the 55th anniversary of its independence, resulting in the replacement of the Barbadian monarchy with a president elected through an electoral college. Barbados would then cease to be a Commonwealth realm, but could maintain membership in the Commonwealth of Nations, like Guyana and Trinidad and Tobago.
On 20 September 2021, just over a full year after the announcement for the transition was made, the Constitution (Amendment) (No. 2) Bill, 2021 was introduced in the Parliament of Barbados. Passed on 6 October, the Bill made amendments to the Constitution of Barbados, introducing the office of the president of Barbados to replace the role of Elizabeth II as Queen of Barbados. The following week, on 12 October 2021, incumbent Governor-General of Barbados Sandra Mason was jointly nominated by the Prime Minister and the Leader of the Opposition as candidate to be the first president of Barbados, and was subsequently elected on 20 October. Mason took office on 30 November 2021. Prince Charles, the heir apparent to the Barbadian Crown at the time, attended the swearing-in ceremony in Bridgetown at the invitation of the Government of Barbados.
Queen Elizabeth sent a message of congratulations to President Mason and the people of Barbados, saying: "As you celebrate this momentous day, I send you and all Barbadians my warmest good wishes for your happiness, peace and prosperity in the future."
A survey that was conducted between 23 October 2021 and 10 November 2021, by the University of the West Indies showed 34% of respondents being in favour of transitioning to a republic, while 30% were indifferent. Notably, no overall majority was found in the survey; with 24% not indicating a preference and the remaining 12% being opposed to the removal of Queen Elizabeth.
On 20 June 2022, a Constitutional Review Commission was formed and sworn in by Jeffrey Gibson (who at the time was serving temporarily as Acting President of Barbados) to review the Constitution of Barbados.
The commission was given a 15-month timeline to complete its work, which included consulting the public about the new republic and drafting a constitution. Thus, the CRC engaged the public in a number of public meetings, lectures, and Twitter Spaces. The report was announced delayed by August 2023, with the final report submitted 30 June 2024.
In February 2026, prime minister Mia Mottley won her third consecutive election victory by landslide, meaning her Barbados Labour party won again all the 30 seats in the House of Assembly.
