Although the coffee plant originated in Ethiopia, allegedly it was the Sufi monks of Yemen who made the first coffee drink in the 15th century. They needed a way to stay awake all night while meditating, and no doubt—caffeine must have come in handy. Then in 1517, the Ottoman Empire invaded Yemen. They brought some coffee back to the palace and the Ottomans were hooked. The very first public place serving coffee in the world is reported to be in Istanbul, by the name “Kiva Han”—which loosely translates into “coffee house” in Turkish. The culture spread quickly. Throughout the Ottoman Empire, kahvehane (modern Turkish) became a place for men to socialize, and to eventually plan a revolution.
