The earliest inhabitants of Barbados were Amerindian nomads. Three waves of migrants moved north toward North America. The first wave was of the Saladoid-Barrancoid group, who were farmers, fishermen, and ceramists that arrived by canoe from South America (Venezuela's Orinoco Valley) around 350 CE. The Arawak people were the second wave of migrants, arriving from South America around 800 CE. Arawak settlements on the island include Stroud Point, Chandler Bay, Saint Luke's Gully, and Mapp's Cave. According to accounts by descendants of the aboriginal Arawak tribes on other local islands, the original name for Barbados was Ichirouganaim. In the 13th 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 name "Barbados" comes from a Portuguese explorer named Pedro Campos in 1536, who originally called the island Los Barbados ("The Bearded Ones"), upon seeing the appearance of the island's fig trees, whose long hanging aerial roots he thought resembled beards. Between Campos' sighting in 1536 and 1550, Spanish conquistadors seized many Caribs on Barbados and used them as slave labor on plantations. Other Caribs fled the island, moving elsewhere.

British sailors who landed on Barbados in the 1620s at the site of present-day Holetown on the Caribbean coast found the island uninhabited. 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.

Large numbers of Celtic people, mainly from Ireland and Scotland, went to Barbados as indentured servants. Over the next several centuries the Celtic population was used as a buffer between the Anglo-Saxon plantation owners and the larger African population, variously serving as members of the Colonial militia and playing a strong role as allies of the larger African slave population in a long string of colonial rebellions. The modern descendants of this original slave population are sometimes derisively referred to as Red Legs and are some of the poorest inhabitants of modern Barbados. There has also been large scale intermarriage between the African and Celtic populations on the islands. Because the Africans could withstand tropical diseases and the climate much better than the white slave population, and also because those poor whites who had or acquired the means to emigrate often did so, Barbados turned from mainly Celtic in the 17th century to overwhelmingly black by the 20th century.

As the sugar industry developed into the main commercial enterprise, Barbados was divided into large plantation estates that replaced the small holdings of the early British settlers. Some of the displaced farmers relocated to British colonies in North America, most notably South Carolina. To work the plantations, West Africans were transported and enslaved on Barbados and other Caribbean islands. The slave trade ceased in 1804. Thirty years later slavery was abolished in the British Empire 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 six years.

Plantation owners and merchants of British descent dominated local politics. 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 in 1938.

Progress toward more democratic government for Barbados was made in 1951, when universal adult suffrage was introduced, followed by steps toward increased self-government, and in 1961, Barbados achieved internal autonomy.

From 1958 to 1962, Barbados was one of the ten members of the West Indies Federation, and Sir Grantley Adams served as its first and only prime minister. When the federation was dissolved, Barbados reverted to its former status as a self-governing colony. Following several attempts to form another federation composed of Barbados and the Leeward and Windward Islands, Barbados negotiated its own independence at a constitutional conference with the United Kingdom in June 1966. After years of peaceful and democratic progress, Barbados became an independent state within the Commonwealth of Nations on November 30, 1966.
