Barbados is the island most historically associated with the origins of rum as a commercial spirit. While sugar cultivation and rudimentary fermented cane drinks existed elsewhere in the Caribbean from the early 1600s, Barbados is where the technological transition to distillation was first documented systematically, where the word "rumbullion" (later shortened to rum) first appears in written records, and where the oldest continuously operated rum distillery in the world — Mount Gay — has been documented since 1703.
The island is tiny — 34 kilometres long, 23 kilometres wide. Yet its role in the history of rum is disproportionate to its size. In the 17th century, Barbados was the wealthiest colony in the British Empire per capita, its wealth built entirely on sugar and the enslaved people who produced it. Rum was the by-product of sugar — the fermented and distilled molasses left over after sugar crystals were extracted. It was initially given to enslaved workers, used as currency in the African slave trade, traded with North American colonies for food, and eventually exported to Britain and Europe as a luxury product.
