The global spread of coffee growing and drinking began in the Horn of Africa, where, according to legend, coffee trees originated in the Ethiopian province of Kaffa. It is recorded that the fruit of the plant, known as coffee cherries, was eaten by slaves taken from present day Sudan into Yemen and Arabia through the great port of its day, Mocha. Coffee was certainly being cultivated in Yemen by the 15th century and probably much earlier. In an attempt to prevent its cultivation elsewhere, the Arabs imposed a ban on the export of fertile coffee beans, a restriction that was eventually circumvented in 1616 by the Dutch, who brought live coffee plants back to the Netherlands to be grown in greenhouses.
