Flag of Antigua and Barbuda, different colours have different meanings. Red is for the energy of the people, black for the African ancestry, and the yellow, blue and white stands for the sun, sea and sand.
HISTORY AND ETYMOLOGY
Antigua means 'ancient' and Barbuda means 'bearded' in Spanish.
The island of Antigua had an ancient name of Wa'ladli and is now called Wadadli by the locals.
It is possible that Christopher Columbus named Antigua after the icon in the Seville Cathedral, Santa Maria la Antigua.
Pre-Columbian Antigua

Antigua was settled by the Ciboney people as early as 3100 BC. The next tribe that ruled in Antigua was the Arawaks, who moved in from what is now Venezuela in South America.
Around 1100 AD, most Arawaks left the island, and it was later raided and annexed by the Caribs, which had much more superior weapons and seafaring skills. However, due to the difficulty differentiating between the local tribal groups, there may have been much more others than the Caribs and Arawaks.
Post-Columbian Antigua and Barbuda

Although the Spaniards had sightings of the island particularly with Christopher Columbus, they did not colonize it due to the lack of good natural resources (like fresh water) and the hostile locals. The British did, however, do so in 1632 with Antigua and in 1684 with Barbuda. Other than a short French period there, all remained until 1981.
Independent sovereign state

Although it being a British colony, most of the currency used before the silver crisis of 1873 were the Spanish and Mexican dollars. In 1838, it was regulated that Antigua and Barbuda should adopt the sterling currency on or by 1847. However, the pieces of eight continued to circulate in the colony.
From 1949, they switched to the British West Indies Dollar until 1955, when the decimal coinage was introduced. $4.80 = £1 was the exchange rate.
Finally, after independence, Antigua and Barbuda joined numerous states to use the Eastern Caribbean Dollar as their official currency.
