Early history
The first indigenous people were Amerindians who arrived here from Venezuela around approximately 350-400 B.C. The Arawak people were the second wave of migrants, arriving from South America around 800. In the thirteenth century, the Caribs arrived from South America in the third wave, displacing both the Arawak and the Salodoid-Barrancoid. For the next few centuries, the Caribs — like the Arawak and the Salodoid-Barrancoid — lived in isolation on the island.

The Portuguese then briefly claimed Barbados from the mid 1500s to the 1600s, their conquistadors may have seized the indigenous Caribs on Barbados and used them as slave labour. Other Caribs are believed to have fled the island to neighbouring islands. Apart from possibly displacing the Caribs, the Portuguese left little impact and by the 1610s, they left for South America leaving the island uninhabited.

British colonial rule

British sailors who landed on Barbados in 1625 arrived at the site of present-day Holetown. At the time only feral pigs which were left behind from the Portuguese. From the arrival of the first British settlers in 1627–1628 until independence in 1966, Barbados was under uninterrupted British control. Nevertheless, Barbados always enjoyed a large measure of local autonomy. Its House of Assembly began meeting in 1639. Among the initial important British figures was Sir William Courten.

With the increased implementation of slave codes, which created differential treatment between Africans and the white settlers, the island became increasingly unattractive to poor whites. Black or slave codes were implemented in 1661, 1676, 1682, and 1688. In response to these codes, several slave rebellions were attempted or planned during this time, but none succeeded. However, an increasingly repressive legal system caused the gap between the treatment of typically white indentured servants and black slaves to widen. Imported slaves became much more attractive for the rich planters who would increasingly dominate the island not only economically but also politically. Some have speculated that, because the Africans could withstand tropical diseases and the climate much better than the white slave population, the white population decreased. This is inconsistent with the fact that many poor whites simply migrated to neighbouring islands and remained in tropical climates. Nevertheless, as those poor whites who had or acquired the means to emigrate often did so, and with the increased importation of African slaves, Barbados turned from mainly Celtic in the seventeenth century to overwhelmingly black by the nineteenth century.

Barbados eventually had one of the world's biggest sugar industries after migrant Brazilian Jews introduced the sugarcane to the island in the 1800s. This quickly replaced tobacco plantations on the islands which were previously the main export. As the sugar industry developed into its main commercial enterprise, Barbados was divided into large plantation estates that replaced the smallholdings of the early British settlers. Some of the displaced farmers moved to British colonies in North America, most notably South Carolina, Panama and British Guiana. To work the plantations, West Africans were transported and enslaved on Barbados and other Caribbean islands. The British abolished the slave trade in 1807. In 1816, the continuation of slavery caused the largest major slave rebellion in the island's history. 20,000 slaves from over 70 plantations rebelled. Whites were driven off of plantations, yet mass killings were avoided. Later termed “Bussa’s Rebellion” after the slave ranger Bussa who with his assistants hated slavery, found the treatment of slaves on Barbados to be “intolerable,” and believed the political climate in Britain made the time ripe to peacefully negotiate with planters for freedom (Davis, p. 211, Northrup, p. 191). Brussa’s Rebellion failed. 120 died in combat or were immediately executed; another 144 were brought to trial and executed; remaining rebels were shipped off the island (Davis, pp. 212-213). Slavery was abolished in the British Empire 18 years later in 1834. In Barbados and the rest of the British West Indian colonies, full emancipation from slavery was preceded by an apprenticeship period that lasted four years.

In 1884, the Barbados Agricultural Society sent a letter to Sir Francis Hincks requesting his private and public views on whether the Dominion of Canada would favourably entertain having the then colony of Barbados admitted as a member of the Canadian Confederation. Asked of Canada were the terms of the Canadian side to initiate discussions, and whether or not the island of Barbados could depend on the full influence of Canada in getting the change agreed to by Britain. Then in 1952 the Barbados Advocate newspaper polled several prominent Barbadian politicians, lawyers, businessmen, the Speaker of the Barbados House of Assembly and later as first President of the Senate, Sir Theodore Branker, Q.C. and found them to be in favour of immediate federation of Barbados along with the rest of the British Caribbean with complete Dominion Status within five years from the date of inauguration of the West Indies Federation with Canada.

However, plantation owners and merchants of British descent still dominated local politics, owing to the high income qualification required for voting. More than 70% of the population, many of them disenfranchised women, were excluded from the democratic process. It was not until the 1930s that the descendants of emancipated slaves began a movement for political rights. One of the leaders of this movement, Sir Grantley Adams, founded the Barbados Labour Party, then known as the Barbados Progressive League, in 1938. Though a staunch supporter of the monarchy, Adams and his party demanded more rights for the poor and for the people. Progress toward a more democratic government in Barbados was made in 1942, when the exclusive income qualification was lowered and women were given the right to vote. By 1949 governmental control was wrested from the planters and, in 1958, Adams became Premier of Barbados.

From 1958 to 1962, Barbados was one of the ten members of the West Indies Federation, an organisation doomed by nationalistic attitudes and by the fact that its members, as colonies of Britain, held limited legislative power. Adams served as its first and only "Premier", but his leadership failed in attempts to form similar unions, and his continued defence of the monarchy was used by his opponents as evidence that he was no longer in touch with the needs of his country. Errol Walton Barrow, a fervent reformer, became the new people's advocate. Barrow had left the BLP and formed the Democratic Labour Party as a liberal alternative to Adams' conservative government. Barrow instituted many progressive social programmes, such as free education for all Barbadians, and the School Meals system. By 1961, Barrow had replaced Adams as Premier and the DLP controlled the government.

With the Federation dissolved, Barbados had reverted to its former status, that of a self-governing colony. The island negotiated its own independence at a constitutional conference with the United Kingdom in June 1966. After years of peaceful and democratic progress, Barbados finally became an independent state within the Commonwealth of Nations on November 30,1966, with Errol Barrow its first Prime Minist
