They are native to the Malucca Islands but now are certainly cultivated worldwide. Cloves were actually one of the first globally traded spices in the world, going as far back as 1721 B.C.E. They were highly prized by the Romans and the Chinese. The Chinese were known to chew them before an audience with the emperor to make sure their breath was fresh. By the 16th and 17th century they had, along with nutmeg, become the most precious spice on the market. In 1605, the Dutch tried to gain a monopoly on the trade by going to the Maluccas and controlling as much land containing cloves as they could.
