By 1660, Barbados generated more trade than all the other English colonies combined. This remained so until it was eventually surpassed by geographically larger islands like Jamaica in 1713. But even so, the estimated value of the colony of Barbados in 1730–1731 was as much as £5,500,000. Bridgetown, the capital, was one of the three largest cities in English America (the other two being Boston, Massachusetts and Port Royal, Jamaica.) By 1700, the English West Indies produced 25,000 tons of sugar, compared to 20,000 for Brazil, 10,000 for the French islands and 4,000 for the Dutch islands. This quickly replaced tobacco, which had been the island's main export.
